str_getcsv
If you want to keep the original capitalization when replacing some text (e.g. for highlighting the search-string in the the search result), you can use this code I wrote:
<?php
// http://devboard.viathinksoft.de/viewtopic.php?f=34&t=771
// Bugfix-Release #3 (June, 22th 2009)
function ext_str_ireplace($findme, $replacewith, $subject)
{
// Replaces $findme in $subject with $replacewith
// Ignores the case and do keep the original capitalization by using $1 in $replacewith
// Required: PHP 5
$rest = $subject;
$result = '';
while (stripos($rest, $findme) !== false) {
$pos = stripos($rest, $findme);
// Remove the wanted string from $rest and append it to $result
$result .= substr($rest, 0, $pos);
$rest = substr($rest, $pos, strlen($rest)-$pos);
// Remove the wanted string from $rest and place it correctly into $result
$result .= str_replace('$1', substr($rest, 0, strlen($findme)), $replacewith);
$rest = substr($rest, strlen($findme), strlen($rest)-strlen($findme));
}
// After the last match, append the rest
$result .= $rest;
return $result;
}
?>
説明
この関数は、subject の中に現れるすべての search (大文字小文字を区別しない)を replace に置き換えた文字列あるいは配列を返します。 一般に、凝った置換ルールが必要ないのであれば、 preg_replace() で i 修正子を使用するかわりにこの関数を使用すべきです。
パラメータ
- search
-
注意: すべての search 配列による置換は、 直前の置換の結果に対して作用します。
- replace
-
- subject
-
subject が配列の場合は、そのすべての要素に 対して検索と置換が行われ、返される結果も配列となります。
- count
-
needles の中で、マッチして置換を行った数を count に返します。このパラメータは参照渡しとします。
search および replace が配列の場合は、 str_ireplace() はそれぞれの配列から取り出した 値を使用して subject の置換を行います。 replace の要素数が search より少ない場合は、残りの要素は 空の文字列に置き換えられます。もし search が配列で replace が文字列だった場合は すべての search が同じ文字列に置き換えられます。
返り値
置換した文字列あるいは配列を返します。
変更履歴

Here's a different approach to search result keyword highlighting that will match all keyword sub strings in a case insensitive manner and preserve case in the returned text. This solution first grabs all matches within $haystack in a case insensitive manner, and the secondly loops through each of those matched sub strings and applies a case sensitive replace in $haystack. This way each unique (in terms of case) instance of $needle is operated on individually allowing a case sensitive replace to be done in order to preserve the original case of each unique instance of $needle.
<?php
function highlightStr($haystack, $needle, $highlightColorValue) {
// return $haystack if there is no highlight color or strings given, nothing to do.
if (strlen($highlightColorValue) < 1 || strlen($haystack) < 1 || strlen($needle) < 1) {
return $haystack;
}
preg_match_all("/$needle+/i", $haystack, $matches);
if (is_array($matches[0]) && count($matches[0]) >= 1) {
foreach ($matches[0] as $match) {
$haystack = str_replace($match, '<span style="background-color:'.$highlightColorValue.';">'.$match.'</span>', $haystack);
}
}
return $haystack;
}

This function will highlight search terms (Key Words in Context).
The difference between this one and the ones below is that it will preserve the original case of the search term as well. So, if you search for "american" but in the original string it is "American" it will retain the capital "A" as well as the correct case for the rest of the string.
<?php
function kwic($str1,$str2) {
$kwicLen = strlen($str1);
$kwicArray = array();
$pos = 0;
$count = 0;
while($pos !== FALSE) {
$pos = stripos($str2,$str1,$pos);
if($pos !== FALSE) {
$kwicArray[$count]['kwic'] = substr($str2,$pos,$kwicLen);
$kwicArray[$count++]['pos'] = $pos;
$pos++;
}
}
for($I=count($kwicArray)-1;$I>=0;$I--) {
$kwic = '<span class="kwic">'.$kwicArray[$I]['kwic'].'</span>';
$str2 = substr_replace($str2,$kwic,$kwicArray[$I]['pos'],$kwicLen);
}
return($str2);
}
?>

Example for str_ireplace(). It will print "RePlaCeMe" in red color, but after this, it would be written in lower case because of the string $search.
<?php
$search = 'replaceme';
$replace = '<font color="#FF0000">'.$search.'</font>';
$text = 'Please RePlaCeMe, OK?';
echo str_ireplace($search, $replace, $text);
?>
Example for ext_str_ireplace(). It will print "RePlaCeMe" in red color, and will not change the capitalization:
<?php
$search = 'replaceme';
$replace = '<font color="#FF0000">$1</font>';
$text = 'Please RePlaCeMe, OK?';
echo ext_str_ireplace($search, $replace, $text);
?>

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;
}
}
?>

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
/**
* Output the HTML debugging string in color coded glory for a sql query
* This is very nice for being able to see many SQL queries
* @access public
* @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]
* @version 1.0
* @date 04/05/05
* @todo highlight SQL functions.
*/
function SQL_DEBUG( $query )
{
if( $query == '' ) return 0;
global $SQL_INT;
if( !isset($SQL_INT) ) $SQL_INT = 0;
//[dv] this has to come first or you will have goofy results later.
$query = preg_replace("/['\"]([^'\"]*)['\"]/i", "'<FONT COLOR='#FF6600'>$1</FONT>'", $query, -1);
$query = str_ireplace(

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

This functionality is now implemented in the PEAR package PHP_Compat.
More information about using this function without upgrading your version of PHP can be found on the below link:
