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); } } ?>

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: http://pear.php.net/package/PHP_Compat

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", " ", $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.

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.

If you want to do string highlighting, for example highlighting search terms, try str_highlight(). http://aidanlister.com/repos/v/function.str_highlight.php

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", "'$1'", $query, -1); $query = str_ireplace( array ( '*', 'SELECT ', 'UPDATE ', 'DELETE ', 'INSERT ', 'INTO', 'VALUES', 'FROM', 'LEFT', 'JOIN', 'WHERE', 'LIMIT', 'ORDER BY', 'AND', 'OR ', //[dv] note the space. otherwise you match to 'COLOR' ;-) 'DESC', 'ASC', 'ON ' ), array ( "*", "SELECT ", "UPDATE ", "DELETE ", "INSERT ", "INTO", "VALUES", "FROM", "LEFT", "JOIN", "WHERE", "LIMIT", "ORDER BY", "AND", "OR ", "DESC", "ASC", "ON " ), $query ); echo "SQL[".$SQL_INT."]: ".$query."; \n"; $SQL_INT++; } //SQL_DEBUG ?>

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; } }
