imagettfbbox
"php at yvanrodrigues dot com" is right...this function is not reliable on extended characters. User beware.
In my case, it produced different results with OpenType vs. TrueType versions of the same font. (Converted my OT font to TT using FontForge as suggested. Strangely, the resulting TT font file was twice as big as the OT version and didn't look the same...heavier weight and slightly different spacing.) While the TT version was more accurate at displaying certain characters, neither was totally reliable, both yielding boxes in place of perfectly valid character glyphs that I could verify existed in the font. (Both fonts showed the same characters perfectly on an HTML page with UTF-8 charset.)
What's more, using this same function with the same font on our development vs. production server also produced different results: some chars worked on dev but not production. Stranger still, the font spacing and size were slightly different between the two. Font file is identical. Dev server is Linux, production server is Windows, but should that matter? Suspect it has more to do with differing versions of FreeType (2.1 vs. 1.9 respectively).
Anyway, careful with this function...best to stick within the rather small range of safe characters and avoid anything else.
imagettftext
(PHP 4, PHP 5)
imagettftext — Write text to the image using TrueType fonts
Description
array imagettftext
( resource $image
, float $size
, float $angle
, int $x
, int $y
, int $color
, string $fontfile
, string $text
)
Writes the given text into the image using TrueType fonts.
Parameters
- image
-
An image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
- size
-
The font size. Depending on your version of GD, this should be specified as the pixel size (GD1) or point size (GD2).
- angle
-
The angle in degrees, with 0 degrees being left-to-right reading text. Higher values represent a counter-clockwise rotation. For example, a value of 90 would result in bottom-to-top reading text.
- x
-
The coordinates given by x and y will define the basepoint of the first character (roughly the lower-left corner of the character). This is different from the imagestring(), where x and y define the upper-left corner of the first character. For example, "top left" is 0, 0.
- y
-
The y-ordinate. This sets the position of the fonts baseline, not the very bottom of the character.
- color
-
The color index. Using the negative of a color index has the effect of turning off antialiasing. See imagecolorallocate().
- fontfile
-
The path to the TrueType font you wish to use.
Depending on which version of the GD library PHP is using, when fontfile does not begin with a leading / then .ttf will be appended to the filename and the library will attempt to search for that filename along a library-defined font path.
When using versions of the GD library lower than 2.0.18, a space character, rather than a semicolon, was used as the 'path separator' for different font files. Unintentional use of this feature will result in the warning message: Warning: Could not find/open font. For these affected versions, the only solution is moving the font to a path which does not contain spaces.
In many cases where a font resides in the same directory as the script using it the following trick will alleviate any include problems.
<?php
// Set the enviroment variable for GD
putenv('GDFONTPATH=' . realpath('.'));
// Name the font to be used (note the lack of the .ttf extension)
$font = 'SomeFont';
?> - text
-
The text string in UTF-8 encoding.
May include decimal numeric character references (of the form: €) to access characters in a font beyond position 127. The hexadecimal format (like ©) is supported as of PHP 5.2.0. Strings in UTF-8 encoding can be passed directly.
Named entities, such as ©, are not supported. Consider using html_entity_decode() to decode these named entities into UTF-8 strings (html_entity_decode() supports this as of PHP 5.0.0).
If a character is used in the string which is not supported by the font, a hollow rectangle will replace the character.
Return Values
Returns an array with 8 elements representing four points making the bounding box of the text. The order of the points is lower left, lower right, upper right, upper left. The points are relative to the text regardless of the angle, so "upper left" means in the top left-hand corner when you see the text horizontally.
Examples
Example #1 imagettftext() example
This example script will produce a white PNG 400x30 pixels, with the words "Testing..." in black (with grey shadow), in the font Arial.
<?php
// Set the content-type
header('Content-type: image/png');
// Create the image
$im = imagecreatetruecolor(400, 30);
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);
// The text to draw
$text = 'Testing...';
// Replace path by your own font path
$font = 'arial.ttf';
// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);
// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>
The above example will output something similar to:
Notes
Note: This function requires both the GD library and the » FreeType library.

After many hours of failure may I suggest:
This function will work on OpenType fonts with Postscript outlines, but from what I can tell, characters > ASCII 127 do not display correctly or at all, even if the text is correctly coded as UTF-8.
Converting the font to truetype or possibly OpenType with truetype outlines; or buying the font as such fixes the problem.
I used FontForge to open the otf and export as ttf and it works perfectly.

I had an image generator where the user could position where they wanted the text to begin - however it kept going off the side of an image. So I made this basic function: it measures if the inputted text and x-position will cause the string to go off the edge, and if so, it will fit as much as it can on the first line, then go down to the next one.
Limitations:
-It only performs this once (i.e. it won't split into three lines)
-I'm pretty sure it won't work with angled text.
<?PHP
function imagettftextwrap($im, $size, $angle, $x_pos, $y_pos, $color, $font, $instr)
{
$box = @imagettfbbox($size, 0, $font, $instr);
$width = abs($box[4] - $box[0]);
$height = abs($box[3] - $box[5]);
$overlap = (($x_pos + $width) - imagesx($im));
if($overlap > 0) //if the text doesn't fit on the image
{
$chars = str_split($instr);
$str = "";
$pstr = "";
for($m=0; $m < sizeof($chars); $m++)
{
$bo = imagettfbbox($fsize1, 0, $font1, $str);
$wid = abs($bo[4] - $bo[0]);
if(($x_pos1 + $wid) < imagesx($im)) //add one char from the string as long as it's not overflowing
{
$pstr .= $chars[$m];
$bo2 = imagettfbbox($fsize1, 0, $font1, $pstr);
$wid2 = abs($bo2[4] - $bo2[0]);
if(($x_pos1 + $wid2) < imagesx($im))

imagettftext($im, $size, $angle, 0, $y_pos + $height, $color, $font, $restof); //and the rest of it

I updated my imagettftextbox function considerably. It fixes the problems of the older imagettftextbox code I uploaded a few months ago (that's now gone).
You can get it here:
http://sk89q.therisenrealm.com/2008/08/ttf-textbox-in-php/
It has both horizontal and vertical alignment, custom line spacing, borders, width, height, etc.

I worked out a script the allows the transfer of alphanumeric data to be placed on an image. The HTML feature is img src and the php feature is imagettftext. This simple code will increment from 1 to 3 on images.
code:
<?php
//ImageCall.php -- This script will call a script to produce the image.
for($next = 1;$next < 4; $next++){
print "Image $next:<br>";
print "<img src = 'Image.php?\$text=$next'>";
print "<br><br>";
}
?>
<?php
//Image.php -- This script creates a square image and places the text on it.
// image size and color
$im = ImageCreate(77,77);
$color1 = ImageColorAllocate($im,0x66,0xCC,0x00);
$color2 = ImageColorAllocate($im,0x33,0x66,0x00);
$color3 = ImageColorAllocate($im,0x00,0x99,0x00);
$color4 = ImageColorAllocate($im,0x3D,0x3D,0x3D);
// image creation
ImageFilledRectangle($im,1,1,76,76,$color1);
ImageFilledpolygon($im, array (76,1,1,76,76,76),3,$color2);
ImageFilledRectangle($im,5,5,72,72,$color3);
// determine numeric center of image
$size = ImageTTFBBox(45,0,'impact',$_GET['$text']);
$X = (77 - (abs($size[2]- $size[0])))/2;
$Y = ((77 - (abs($size[5] - $size[3])))/2 + (abs($size[5] - $size[3])));
//places numeric information on image
ImageTTFText($im,45,0,($X-1),$Y,$color4,'impact',$_GET['$text']);
//returns completed image to calling script
Header('Content-Type: image/png');
Imagepng($im);

If you're looking for easy text alignment, you need to use the imagettfbbox() command. When given the correct parameters, it will return the boundaries of your to-be-made text field in an array, which will allow you to calculate the x and y coordinate that you need to use for centering or aligning your text.
A horizontal centering example:
<?php
$tb = imagettfbbox(17, 0, 'airlock.ttf', 'Hello world!');
?>
$tb would contain:
Array
(
[0] => 0 // lower left X coordinate
[1] => -1 // lower left Y coordinate
[2] => 198 // lower right X coordinate
[3] => -1 // lower right Y coordinate
[4] => 198 // upper right X coordinate
[5] => -20 // upper right Y coordinate
[6] => 0 // upper left X coordinate
[7] => -20 // upper left Y coordinate
)
For horizontal alignment, we need to substract the "text box's" width { $tb[2] or $tb[4] } from the image's width and then substract by two.
Saying you have a 200px wide image, you could do something like this:
<?php
$x = ceil((200 - $tb[2]) / 2); // lower left X coordinate for text
imagettftext($im, 17, 0, $x, $y, $tc, 'airlock.ttf', 'Hello world!'); // write text to image
?>
This'll give you perfect horizontal center alignment for your text, give or take 1 pixel. Have fun!

First of all, thanks sk89q for the func! it was exactly I was looking for.
I made a change. Depending on the letter, the text were incorrect vertical aligned.
I replace the line:
$line_height = $dimensions[1] - $dimensions[7];
for the following:
$line_height = $size+4;
No matter if mama or jeje is written, the vertical position will be the same.

Here is an update to my imagettftextwrapped function. I had posted the old version that cut off lines if it wordwrapped.
Here's a new version with the bug fixed, a list of arguments closer to imagettftext(), and partial angle support (the text is angled, but the left margins for each line are not adjusted for the angle).
It's a function I wrote a few years ago to do unjustified aligned text.
<?php
define("ALIGN_LEFT", "left");
define("ALIGN_CENTER", "center");
define("ALIGN_RIGHT", "right");
function imagettftextbox(&$image, $size, $angle, $left, $top, $color, $font, $text, $max_width)
{
$text_lines = explode("\n", $text); // Supports manual line breaks!
$lines = array();
$line_widths = array();
$largest_line_height = 0;
foreach($text_lines as $block)
{
$current_line = ''; // Reset current line
$words = explode(' ', $block); // Split the text into an array of single words
$first_word = TRUE;
$last_width = 0;
for($i = 0; $i < count($words); $i++)
{
$item = $words[$i];
$dimensions = imagettfbbox($size, $angle, $font, $current_line . ($first_word ? '' : ' ') . $item);
$line_width = $dimensions[2] - $dimensions[0];
$line_height = $dimensions[1] - $dimensions[7];
if($line_height > $largest_line_height) $largest_line_height = $line_height;
if($line_width > $max_width && !$first_word)
{
$lines[] = $current_line;
$line_widths[] = $last_width ? $last_width : $line_width;
/*if($i == count($words))
{
continue;
}*/
$current_line = $item;
}
else
{
$current_line .= ($first_word ? '' : ' ') . $item;
}
if($i == count($words) - 1)
{
$lines[] = $current_line;
$line_widths[] = $line_width;
}
$last_width = $line_width;
$first_word = FALSE;
}
if($current_line)
{
$current_line = $item;
}
}
$i = 0;
foreach($lines as $line)
{
if($align == ALIGN_CENTER)
{
$left_offset = ($max_width - $line_widths[$i]) / 2;
}
elseif($align == ALIGN_RIGHT)
{
$left_offset = ($max_width - $line_widths[$i]);
}
imagettftext($image, $size, $angle, $left + $left_offset, $top + $largest_line_height + ($largest_line_height * $i), $color, $font, $line);
$i++;
}
return $largest_line_height * count($lines);
}

Hi All,
I struggled for moths to do a decent text warp with GD lib. Here is the code that I made use of:
<?php
//word wrap
$warpText = wordwrap($text, 30, "\n");
//display text
imagettftext($image, $fontSize, 0, $x, $y, $fontColor, $font, $warpText);
?>
Hope this helps somebody.

Sorry my English.
I have trouble with using imagettftext under Windows.
I can't used short name of fonts(example "arial","arialbd.ttf" etc). PHP say what not find this font.
Manipulation with environment GDFONTPATH lost.
This is my solution
<?php
$dir=opendir('./font/');//directory with fonts
if($dir)
while($f=readdir($dir)){
if(preg_match('/\.ttf$/',$f)){
$font=explode('.',$f);
define($font[0],realpath('./font/'.$f));
}
}
if($dir)
closedir($dir);
?>
Directory "font" have two file: arial.ttf and arialbd.ttf
Now one can using constant font name by calling imagettftext:
imagettftext($img,12,0,25,28,$color,arialbd,'some text');

Small but very dangerous bug in function ttfWordWrappedText, written by waage, just try ttfWordWrappedText("aaaaa\naa",4) and your script will run into endless loop.
You can fix it with code below:
<?php
function ttfWordWrappedText_fixed($text, $strlen = 8) {
$text = urldecode($text);
$text = explode("\n", $text);
$i = 0;
foreach($text as $text)
{
while(strlen($text) > $strlen && strstr($text, ' ') !== FALSE) {
$startPoint = strpos($text, ' ');
$line[$i][] =substr($text,0,$startPoint);
$text = trim(strstr($text, ' '));
}
$line[$i][] = trim($text);
}
$line[$i][] = trim($text);
$i++;
}
return $line;
}
?>
better solutions is to check input text for lines longer than needed wrap point.

For those trying to disable the font smoothing or font cleartype:ing, take a look at the color parameter for this function. The correct word for what you're looking for is antialiasing.

Just to comment on Sohel Taslims great function...
if anyone needs to add BACKGROUND TRANSPARENCY to this kind of function (which almost does everyone one would want already) then add
$bg_color = imagecolorat($im,1,1);
imagecolortransparent($im, $bg_color);
ABOVE the "if($L_R_C == 0){ //Justify Left" line

I had some issues trying to get both word wrapping and new line detection but with some of the help from the comments below i got this. (thanks to jwe for the main part of the code here)
<?php
function ttfWordWrappedText($text, $strlen = 38) {
$text = urldecode($text);
$text = explode("\n", $text);
$i = 0;
foreach($text as $text)
{
while(strlen($text) > $strlen) {
$startPoint = $strlen - 1;
while(substr($text, $startPoint, 1) != " ") {
$startPoint--;
}
$line[$i][] = trim(substr($text, 0, $startPoint));
$text = substr($text, $startPoint);
}
$line[$i][] = trim($text);
$i++;
}
return $line;
}
?>
This returns an array for each newline entered and subarray for each wordwrapped line to print.
ie.
Array
(
[0] => Array
(
[0] => This is the first long line
[1] => that i entered.
)
[1] => Array
(
[0] => And this is the new line after that.
)
)

If you're having issues with fonts not working... (Could not find/open font) check your permissions on the folder/font files and make sure they're 775, especially if you've just pulled them from a windows box. Hope this helps!

Right align out of "webmaster at higher-designs dot com" code
<?php

$textheight = abs($box[5] - $box[1]);
$xcord = $imagewidth - ($textwidth)-2; // 2 = some space from right side.
$ycord = ($imageheight/2)+($textheight/2);

Creating multiline text with GD is bit complicated, one of the issues I've ran to is how to set line spacing, a normal feature in all type setting (even type writers). By default, line spacing with imagettftext seems to be 150 % or more, too much for me anyhow. Thus I've used the function below to get the lines closer to each other. By default, it appears to create 100 % linespacing, but it has not been tested thoroughly.
null imagettfmultilinetext
(resource $image, float $size, float $angle, int $x, int $y, int $color, string $fontfile, string $text , $spacing)
spacing is a coefficient, comparable to Line spacing in a word processors or graphics software, causing a shift relative to font size in the line spacing
<?php
function imagettfmultilinetext($image, $size, $angle, $x, $y, $color, $fontfile, $text, $spacing=1)
{
$lines=explode("\n",$text);
for($i=0; $i< count($lines); $i++)
{
$newY=$y+($i * $size * $spacing);
imagettftext($image, $size, $angle, $x, $newY, $color, $fontfile, $lines[$i], $spacing);
}
return null;
}
?>

Strangely this function seems to work with adobe post script files (tried .pfb) not sure why this isn't documented or why there is a separate set of functions for dealing with postscript.

Users may note a problem trying to use this function to display the Euro symbol.
The reason is that it is a late addition. Although the operating systems generally recognise code 0x80 (128 decimal) as Euro, this is not where it necessarily appears in the font. Some have it there, but many just have it in the extended character set at position 0x20AC (8364 decimal).
I have yet to find a font with it only at 0x80, so here is the fix:
<?php
$image=imagecreate(135,24);
$bg=imagecolorallocate($image,0,0,0);
$fg=imagecolorallocate($image,0,255,0);
$text = 'coffee - €3.50';
$friendly = eurofix($text);
imagettftext($image,16,0,5,20,$fg,"Papyrus.ttf",$friendly);
imagegif ($image);
imagedestroy ($image);
function eurofix($str) {
$euro=utf8_encode('€');
$str = preg_replace('/\x80/',$euro,$str);
return ($str);
}
?>
You should note, however, this won't help with fonts older than about 1999. It can only make sure the Euro is displayed where available.

Roy van Arem suggested a neat code for listing TTFs on a machine. However, it has some problems (such as lower and upper case distinction of file extension and defective fonts) that I have corrected in the following script, which can be implemented as a single PHP script (name as you like):
<?php //make sure there are no blank lines above
$ffolder="/usr/local/bin/fonts"; //The directory where your fonts reside
if (empty($_GET['f']))
{
$folder=dir($ffolder); //open directory
echo "<HTML><BODY>\n";
while($font=$folder->read())
if(stristr($font,'.ttf')) //only ttf fonts
$fonts[]=
