str_getcsv
My apologies. I'm a PHP newbie and the count function on my script below didn't work right if you have more than one "keyword". I searched and spent a long time to get this to work right, so wanted to share it.
This is very easy to use by doing the following.
$text - is the text to search
$words - are the words to highlight (search text)
$the_place - is so that you can tell your users what "area" was searched.
<?php
function highlight_this($text, $words, $the_place) {
$words = trim($words);
$the_count = 0;
$wordsArray = explode(' ', $words);
foreach($wordsArray as $word) {
if(strlen(trim($word)) != 0)
//exclude these words from being replaced
$exclude_list = array("word1", "word2", "word3");
// Check if it's excluded
if ( in_array( strtolower($word), $exclude_list ) ) {
} else {
$text = str_ireplace($word, "<span class=\"highlight\">".strtoupper($word)."</span>", $text, $count);
$the_count = $count + $the_count;
}
}
//added to show how many keywords were found
echo "<br><div class=\"emphasis\">A search for <strong>" . $words. "</strong> found <strong>" . $the_count . "</strong> matches within the " . $the_place. ".</div><br>";
return $text;
}
//example of how to use
$text_to_highlight = highlight_this($text_to_highlight, $search_text, "Place you searched");
?>
Περιγραφή
mixed str_ireplace
( mixed $search
, mixed $replace
, mixed $subject
[, int $&count
] )
Η συνάρτηση αυτή επιστρέφει ένα string ή έναν πίνακα, στον οποίο η κάθε εμφάνιση της παραμέτρου search στο string subject (ignoring case) έχει αντικατασταθεί από την τιμή replace . Εάν δε θέλετε περίπλοκους κανόνες αντικατάστασης, θα πρέπει να χρησιμοποιείται αυτή τη συνάρτηση αντί της eregi_replace() ή της preg_replace() με τον modifier i.
Εάν η παράμετρος subject είναι ένας πίνακας, τότε η έρευνα και η αντικατάσταση υλοποιούνται με κάθε στοιχείο του subject , και η επιστρεφόμενη τιμή είναι ένας πίνακας.
Εάν οι παράμετροι search και replace είναι πίνακες, τότε η συνάρτηση str_ireplace() πέρνει μία τιμή από κάθε πίνακα και τη χρησιμοποιεί για έρευνα και αντικατάσταση επί του subject . Εάν ο πίνακας replace έχει λιγότερες τιμές από τον search , τότε χρησιμοποιείται ένα κενό string για τις υπόλοιπες τιμές αντικατάστασης. Εάν η search είναι ένας πίνακας και η replace ένα string, τότε αυτό το string αντικατάστασης χρησιμοποιείται για κάθε τιμή του search .
Example#1 Παράδειγμα χρήσης της str_ireplace()
<?php
$bodytag = str_ireplace("%body%", "black", "<body text=%BODY%>");
?>
Η συνάρτηση αυτή είναι binary safe.
Note: Από την PHP 5.0.0 ο αριθμός των ταιριασμένων και αντικατεστημένων needles θα επιστρέφεται με την παράμετρο count , η οποία θα περνάται με αναφορά. Στις εκδόσεις πριν την PHP 5.0.0 η παράμετρος αυτή δεν είναι διαθέσιμη.
Ανατρέξτε επίσης στις: str_replace(), ereg_replace(), preg_replace(), και strtr().

I modified a script from notes on the eregi_replace() function page. This is a highlight script that worked good for me.
$text - is the text to search
$words - are the words to highlight (search text)
$the_place - is so that you can tell your users what "area" was searched.
<?php
function highlight_this($text, $words, $the_place) {
$words = trim($words);
$wordsArray = explode(' ', $words);
foreach($wordsArray as $word) {
if(strlen(trim($word)) != 0)
$text = str_ireplace($word, "<span class=\"highlight\">".strtoupper($word)."</span>", $text, $count);
}
//added to show how many keywords were found
echo "<br><div class=\"emphasis\">A search for <strong>" . $words. "</strong> found <strong>" . $count . "</strong> matches within the " . $the_place. ".</div><br>";
//end script modification
return $text;
}
?>

Here are some minor tweaks to-n00b-at-battleofthebits-dot-org's excellent function.
1) The token was set to an ASCII value 1 (which could be changed as was previously noted)
2) The $c++ was not needed
3) The while statement is not necessary for the final replacement
4) Note that this does not allow use of arrays for search and replace terms. That could be implemented using loops.
<?php
if(!function_exists('str_ireplace')){
function str_ireplace($search,$replace,$subject){
$token = chr(1);
$haystack = strtolower($subject);
$needle = strtolower($search);
while (($pos=strpos($haystack,$needle))!==FALSE){
$subject = substr_replace($subject,$token,$pos,strlen($search));
$haystack = substr_replace($haystack,$token,$pos,strlen($search));
}
$subject = str_replace($token,$replace,$subject);
return $subject;
}
}
?>

Dreamhost hasn't upgraded to PHP 5.0 -- I came up with my own alternative, trying to make it run as much like str_ireplace() as possible. Adjust the switch-a-roo token if you think it may conflict with your needle in teh haystack.
## HOMEBREW str_ireplace() FOR PRE-PHP 5.0
if (!function_exists('str_ireplace') {
function str_ireplace($search,$replace,$subject) {
$token = '^[[term^]';
$haystack = strtolower($subject);
$needle = strtolower($search);
while (($pos=strpos($haystack,$needle))!==FALSE) {
$c++;
$subject = substr_replace($subject,$token,$pos,strlen($search));
$haystack = substr_replace($haystack,$token,$pos,strlen($search));
}
while (($pos=strpos($subject,$token))!==FALSE) {
$subject = substr_replace($subject,$replace,$pos,strlen($token));
}
return $subject;
}
}

There appears to be a "bug" with this function in at least version 5.2.1.
If you attempt to use the function while replacing special characters, such as new lines, it will cause your entire scripts to fail. It resulted in my browser (Firefox 2) trying to download the file instead of parsing it.
Here is example code which will cause problems:
<?php
$sometext = "this is some text\n";
$sometext .= "that has a new line in it";
echo break_lines($sometext);
function break_lines ($text)
{
return str_ireplace("\n", "<br/>", $text);
}
?>
However, if you simply get rid of the "i" and use the normal str_replace, the page will load just fine.
I have also tried the same code on 5.2.3 and this version does NOT have the same problem, so it does appear to be an issue that was resolved with the newest builds of php.
I don't think it was a result of my personal environment, but I am running Debian-Sarge, Apache 2 and PHP 5.2.1/5.2.3.

Yet another one str_ireplace ireplacement, this one will take arrays as $search and $replace
<?php
function make_pattern(&$pat, $key) {
$pat = '/'.preg_quote($pat, '/').'/i';
}
if(!function_exists('str_ireplace')){
function str_ireplace($search, $replace, $subject){
if(is_array($search)){
array_walk($search, 'make_pattern');
}
else{
$search = '/'.preg_quote($search, '/').'/i';
}
return preg_replace($search, $replace, $subject);
}
}
?>

str_ireplace for php below version 5. :)
if(!function_exists('str_ireplace')) {
function str_ireplace($search,$replace,$subject) {
$search = preg_quote($search, "/");
return preg_replace("/".$search."/i", $replace, $subject); } }

Note that character case is being defined by your server's locale setting, which effects strings containing non-ASCII characters.
See strtolower() - http://www.php.net/strtolower and comments - internally str_ireplace converts $search and $replace to lowercase to find matches.

here's a neat little function I whipped up to do HTML color coding of SQL strings.
<?php

* @return void. prints HTML color coded string of the input $query.
* @param string $query The SQL query to be executed.
* @author Daevid Vincent [daevid@LockdownNetworks.com]

* @date 04/05/05
* @todo highlight SQL functions.

function SQL_DEBUG( $query )
{
if( $query == '' ) return 0;

if( !isset($SQL_INT) ) $SQL_INT = 0;
//[dv] this has to come first or you will have goofy results later.

If you want to do string highlighting, for example highlighting search terms, try str_highlight().
