str_split
(PHP 5, PHP 7, PHP 8)
str_split — Konvertiert einen String in ein Array
Beschreibung
str_split(string
$string, int $length = 1): arrayKonvertiert einen String in ein Array.
Parameter-Liste
-
string -
Die Eingabezeichenkette.
-
length -
Maximale Länge eines Teilstücks.
Rückgabewerte
Wenn der optionale Parameter length angegeben ist,
enthält das zurückgegebene Array Elemente mit der in
length definierten Länge, andernfalls enthält jedes
Element ein einzelnes Zeichen.
false wird zurückgegeben, wenn length kleiner als
1 ist. Wenn der Parameter length größer als
string ist, wird der gesamte String als ein erstes
(und einziges) Array-Element zurückgegeben.
Beispiele
Beispiel #1 Beispiel für die Verwendung von str_split()
<?php
$str = "Hallo Freund";
$arr1 = str_split($str);
$arr2 = str_split($str, 3);
print_r($arr1);
print_r($arr2);
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Array
(
[0] => H
[1] => a
[2] => l
[3] => l
[4] => o
[5] =>
[6] => F
[7] => r
[8] => e
[9] => u
[10] => n
[11] => d
)
Array
(
[0] => Hal
[1] => lo
[2] => Fre
[3] => und
)
Anmerkungen
Hinweis:
str_split() trennt in Bytes anstatt Zeichen, wenn Multibyte kodierte Zeichenketten vorliegen.

Version of str_split by rlpvandenberg at hotmail dot com is god-damn inefficient and when $i+$j > strlen($text) [last part of string] throws a lot of notice errors. This should work better:
if(! function_exists('str_split'))
{
function str_split($text, $split = 1)
{
$array = array();
for ($i = 0; $i < strlen($text);)
{
$array[] = substr($text, $i, $split);
$i += $split;
}
return $array;
}
}

The manual don't says what is returned when you parse a different type of variable.
This is the example:
<?php
$str1 = "Long"; // More than 1 char
$str2 = "x"; // Only 1 char
$str3 = ""; // Empty String
$str4 = 34; // Integer
$str5 = 3.4; // Float
$str6 = true; // Bool
$str7 = null; // Null
$spl1 = str_split($str1);
$spl2 = str_split($str2);
$spl3 = str_split($str3);
$spl4 = str_split($str4);
$spl5 = str_split($str5);
$spl6 = str_split($str6);
$spl7 = str_split($str7);
echo count($spl1); // 4
echo count($spl2); // 1
echo count($spl3); // 1
echo count($spl4); // 2
echo count($spl5); // 3
echo count($spl6); // 1
echo count($spl7); // 1
print_r($spl1);
print_r($spl2);
print_r($spl3);
print_r($spl4);
print_r($spl5);
print_r($spl6);
print_r($spl7);

I noticed in the post below me that his function would return an array with an empty key at the end.
So here is just a little fix for it.
<?php
//Create a string split function for pre PHP5 versions
function str_split($str, $nr) {
//Return an array with 1 less item then the one we have
return array_slice(split("-l-", chunk_split($str, $nr, '-l-')), 0, -1);

I needed a function that could split a string from the end with any left over chunk being at the beginning of the array (the beginning of the string).
<?php
function str_rsplit($str, $sz)
{
// splits a string "starting" at the end, so any left over (small chunk) is at the beginning of the array.
if ( !$sz ) { return false; }
if ( $sz > 0 ) { return str_split($str,$sz); } // normal split
$l = strlen($str);
$sz = min(-$sz,$l);
$mod = $l % $sz;
if ( !$mod ) { return str_split($str,$sz); } // even/max-length split
// split
return array_merge(array(substr($str,0,$mod)), str_split(substr($str,$mod),$sz));
}
$str = 'aAbBcCdDeEfFg';
str_split($str,5); // return: {'aAbBc','CdDeE','fFg'}
str_rsplit($str,5); // return: {'aAbBc','CdDeE','fFg'}
str_rsplit($str,-5); // return: {'aAb','BcCdD','eEfFg'}

The documentation fails to mention what happens when the string length does not divide evenly with the chunk size. Not sure if the same behavior for all versions of PHP so I offer the following code to determine this for your installation. On mine [version 5.2.17], the last chunk is an array the length of the remaining chars.
<?php
$da_string = "When number of chars does't divide evenly";
$len = strlen($da_string);
$chunk_size = 8;
echo "<p> Length of <span style='font-family:monospace'>$da_string</span>: $len</p>\n";
echo "<p> Chunck size: $chunk_size</p>\n";
$parts = str_split($da_string, $chunk_size);
$html = "<table border='5' cellpadding='3' cellspacing='4'>\n";
foreach ($parts as $idx=>$part)
{
$html .= "<tr>\n";
$html .= "<td style='font-family:monospace'>$part</td>";
$chars = str_split($part);
foreach ($chars as $char)
{
if ($char === ' ')
{
$html .= "<td> </td>";
}
else
{
$html .= "<td>$char</td>";
}
}
$html .= "</tr>\n";
}
$html .= "</table>\n";
echo $html;
?>

The very handy str_split() was introduced in PHP 5, but a lot of us are still forced to use PHP 4 at our host servers. And I am sure a lot of beginners have looked or are looking for a function to accomplish what str_split() does.
Taking advantge of the fact that strings are 'arrays' I wrote this tiny but useful e-mail cloaker in PHP, which guarantees functionality even if JavaScript is disabled in the client's browser. Watch how I make up for the lack of str_split() in PHP 4.3.10.
<?php
// cloackEmail() accepts a string, the email address to be cloaked
function cloakEmail($email) {
// We create a new array called $arChars, which will contain the individula characters making up the email address. The array is blank for now.
$arChars = array();
// We extract each character from the email 'exploiting' the fact that strings behave like an array: watch the '$email[$i]' bit, and beging to fill up the blank array $arChars
for ($i = 0; $i < strlen($email); $i++) { $arChars[] = $email[$i]; }
// Now we work on the $arChars array: extract each character in the array and print out it's ASCII value prefixed with '&#' to convert it into an HTML entity
foreach ($arChars as $char) { print '&#'.ord($char); }
// The result is an email address in HTML entities which, I hope most email address harvesters can't read.
}
print cloakEmail('someone@nokikon.com');
?>
###### THE CODE ABOVE WITHOUT COMMENTS ######
<?php
function cloakEmail($email) {
$arChars = array();
for ($i = 0; $i < strlen($email); $i++) { $arChars[] = $email[$i]; }
foreach ($arChars as $char) { print '&#'.ord($char); }
}
print cloakEmail('someone@nokikon.com');
?>
In creating this little utility, I demonstrated how the lack of str_split() can be made up in PHP < 5. If you got how it was accomplished, you could write a function to do exactly what str_split() does in PHP 5 and even name it 'str_split()'. :)

It's mentioned in the Return Values section above ("If the split_length length exceeds the length of string, the entire string is returned as the first (and only) array element"), but note that an input of empty string will return array(1) { [0]=> string(0) "" }. Interestingly an input of NULL will also return array(1) { [0]=> string(0) "" }.
Compare this with, say, <?php preg_split('//', $inputString, -1, PREG_SPLIT_NO_EMPTY); ?> which will return array(0) { } for an input of empty string or NULL. I find this to be a bit more intuitive.
Hope this helps.

The previous suggestion is almost correct (and will only working for strlen=1. The working PHP4 function is:
<code>
function str_split($text, $split = 1){
//place each character of the string into and array
$array = array();
for ($i=0; $i < strlen($text); $i++){
$key = "";
for ($j = 0; $j < $split; $j++){
$key .= $text[$i+$j];
}
$i = $i + $j - 1;
array_push($array, $key);
}
return $array;
}

string into and array
function str_split_php4($sText, $iSplit = 1)
{
$iSplit=(integer) $iSplit; // sanity check
if ($iSplit < 1) { return false; }
$aResult = array();
for($i=0, $limit=strlen($sText); $i < $limit; $i+=$iSplit) {
$aResult[]=substr($sText, $i, $iSplit);
}
return $aResult;

the fastast way (that fits my needs) to replace str_split() in php 4 i found is this:
<?php
if(!function_exists('str_split')) {
function str_split($string, $split_length = 1) {
$array = explode("\r\n", chunk_split($string, $split_length));
array_pop($array);
return $array;
}
}
?>
i also tested the provided functions in the comments..
(the differences are 0.001 to 0.00001 sec)

I was looking for a function that would split a string into an array like str_split() and found Razor's function above. Just though that I would simplify the code a little.
<?php
function str_split_php4($text, $split = 1){
//place each character of the string into and array
$array = array();
for($i=0; $i < strlen($text); $i++){
$key = NULL;
for ($j = 0; $j < $split; $j++){
$key .= $text[$i];
}
array_push($array, $key);
}
return $array;
}
?>
Both mine and worksRazor's work well, I just prefer to use less code. I could have written one myself, but I was just being lazy.

if (!is_numeric($split) && $split < 1) return false;
$len = strlen($text);
$array = array();
$s = 0;
$e=$split;
while ($s <$len)
{
$e=($e <$len)?$e:$len;
$array[] = substr($text, $s,$e);
$s = $s+$e;
}
return $array;
}
}

For those it may concern:
We encountered trubble when trying to str_split a UTF-8 encoded string, containing such Swedish letters as å, å and ö.
It seems that this function splits according to byte-length and not character length. So if the letter "Å" takes 2 bytes, then str_split() will only return the first bite of the character "Å".
We ain't 100% sure that this is the case but this was anyhow the result we got. So we used the multi-byte functions instead.

If you use PHP 4 and don't need the split_length parameter, here's the shortest replacement:
<?php
preg_split('#(?<=.)(?=.)#s', $str);
?>

this function can perform a reverse str_split. I write it for PHP4 but you can rename It for other versions..
if ( !function_exists('str_split') ) {
function str_split($string,$split_length=1){
$sign = (($split_length<0)?-1:1);
$strlen = strlen($string);
$split_length = abs($split_length);
if ( ($split_length==0) || ($strlen==0) ){
$result = false;
//$result[] = "";
}
elseif ($split_length >= $strlen){
$result[] = $string;
}
else {
$length = $split_length;
for ($i=0; $i<$strlen; $i++){
$i=(($sign<0)?$i+$length:$i);
$result[] = substr($string,$sign*$i,$length);
$i--;
$i=(($sign<0)?$i:$i+$length);
if ( ($i+$split_length) > ($strlen) ){
$length = $strlen-($i+1);
}
else {
$length = $split_length;
}
}
}
return $result;
}
}

Note that in atleast in PHP 5.5.9 (Zend Engine v2.5.0), str_split with an integer value as an argument may return unpredictable results.
If your number contains leading 0's, the result array is unprdictable as it may contain any number of digits from the argument or (mostly) just a 0.
Here are a list of possible values that might be returned:
-Interger
<?php
print_r(str_split(0080450)); // does not work
print_r(str_split(strval(0080450))); // neither this
/*
* Outputs:
* Array
* (
* [0] => 0
* )
*/
?>
BUT
<?php
print_r(str_split(80450)); // works fine
print_r(str_split(strval(80450))); // so does this
/*
* Outputs:
* (
* [0] => 8
* [1] => 0
* [2] => 4
* [3] => 5
* [4] => 0
* )
*/
?>
Floating point numbers have their leading and trailing 0s cut off:
<?php
print_r(str_split(0080450.0010)); // works but.. print_r(str_split(strval(0080450.0010))); // same here..
/*
Outputs:
* Array
* (
* [0] => 8
* [1] => 0
* [2] => 4
* [3] => 5
* [4] => 0
* [5] => .
* [6] => 0
* [7] => 0
* [8] => 1
* )
*/
?>
I'm not sure if this can be considered a bug, since this is due to how type conversion and casting works, so i just posted it here.
I've notced that this is how strval() works. Can anyone shed light into this?..

*
* @param string $string The input string.
* @param int $split_length Maximum length of the chunk. If specified, the returned array will be broken down
* into chunks with each being split_length in length, otherwise each chunk will be one character in length.
* @return array|boolean
* -
* - If the split_length length exceeds the length of string, the entire string is returned
* as the first (and only) array element.
* - False is returned if split_length is less than 1.

function mb_str_split($string, $split_length = 1)
{
if ($split_length == 1) {
return preg_split("//u", $string, -1, PREG_SPLIT_NO_EMPTY);
} elseif ($split_length > 1) {
$return_value = [];
$string_length = mb_strlen($string, "UTF-8");
for ($i = 0; $i < $string_length; $i += $split_length) {
$return_value[] = mb_substr($string, $i, $split_length, "UTF-8");
}
return $return_value;
} else {
return false;
}
}
}

To split UTF-8 into 16-charcater slices you can use:
<?php
preg_split('/(?=(.{16})*$)/u', $text);
?>
You can also use look-behind instead of look-ahead if you want the first (not the last) chunk to be the shortest.

A good way to use this method to convert CamelCase text into nice text would be-
<?php
/**
Returns a formatted string based on camel case.
e.g. "CamelCase" -> "Camel Case".
*/
function FormatCamelCase( $string ) {
$output = "";
foreach( str_split( $string ) as $char ) {
strtoupper( $char ) == $char and $output and $output .= " ";
$output .= $char;
}
return $output;

I think that the last post by carlosreche at yahoo dot com is too complicated.
It's much easier if you do it like this:

if ($length < 1) return false;
$strlen = strlen($str);
$ret = array();
for ($i = 0; $i < $strlen; $i += $length) {
$ret[] = substr($str,$i,$length);
}
return $ret;
}
}
?>
I hope it helps for those with PHP <5

A good use of str_split is reverse translating an amino acid sequence.
<?php
/* reverse translate an aa sequence using its dna counterpart */
function reverseTranslate($aaSeq,$ntSeq){
$nt=str_split($ntSeq,3);
$aa=str_split($aaSeq,1);
$gapChar=array('*','-');
$numAa=count($aa);
$ntIndex=0;
$newNtSeq="";
for($i=0;$i<$numAa;$i++){
// if the aa is a gap, then just put on a gap character
if(in_array($aa[$i],$gapChar)){
$newNtSeq.='---';

Unicode str_split without use of mbstring. Based on PCRE_UTF8 feature.
function mb_str_split($str, $len){
$chars = preg_split('/(?<!^)(?!$)/u', $str );
$out = array();
foreach( array_chunk($chars, $len) as $a ){
$out[] = join("", $a);
}
return $out;
}

Response to "Richard Ayotte 18-Jan-2008 09:27":
Slight tweak to prevent the need to call another preg_replace, there were also some bugs in this that I'm surprised didn't get noticed (causing duplicate replaces between the preg_replace calls) :)
Please feel free to optimize further. I'm not the best with lookahead/behinds yet. I also removed the :upper/lower: and it seemed to speed things up too.
<?php
$test = 'CustomerIDWithSomeOtherJETWords';
preg_replace('/(?!^)[A-Z]{2,}(?=[A-Z][a-z])|[A-Z][a-z]/', ' $0', $test));
?>
Shaves off a little time anyway. :)

Regarding ricordatis comment on preg_match_all('/./u',...) instead of preg_split('//u',...):
You'll have to use the pattern '/./us' with preg_match_all to get exactly the same behaviour w.r.t. newlines. Don't know if this is still faster, though. Oh, and the expected result is in $array[0].

A little one-liner that came in handy. I thought i'd share for those who want to split a string into two parts by the given offset.
<?php
/**
* Split a string into two parts at offset.
*
* @param string $string
* @param integer $offset
* @return mixed array and bool(false) if offset is out of scope
*/
function str_osplit($string, $offset){
return isset($string[$offset]) ? array(substr($string, 0, $offset), substr($string, $offset)) : false;
}
$str = "Split a string into two parts at offset";
var_dump(str_osplit($str, 12));
/**
* Output:
array(2) {
[0]=>
string(12) "Split a stri"
[1]=>
string(27) "ng into two parts at offset"
}
*/
?>

found this great example on a php board for those not using php5, as an alternative to the posts below this
<?php
if(!function_exists('str_split')){
function str_split($string,$split_length=1){
$count = strlen($string);
if($split_length < 1){
return false;
} elseif($split_length > $count){
return array($string);
} else {
$num = (int)ceil($count/$split_length);
$ret = array();
for($i=0;$i<$num;$i++){
$ret[] = substr($string,$i*$split_length,$split_length);
}
return $ret;
}
}
}
?>
