eregi_replace

(PHP 4, PHP 5)

eregi_replaceReplace regular expression case insensitive

Description

string eregi_replace ( string $pattern , string $replacement , string $string )

This function is identical to ereg_replace() except that this ignores case distinction when matching alphabetic characters.

Warning

This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

Parameters

pattern

A POSIX extended regular expression.

replacement

If pattern contains parenthesized substrings, replacement may contain substrings of the form \digit, which will be replaced by the text matching the digit'th parenthesized substring; \0 will produce the entire contents of string. Up to nine substrings may be used. Parentheses may be nested, in which case they are counted by the opening parenthesis.

string

The input string.

Return Values

The modified string is returned. If no matches are found in string, then it will be returned unchanged.

Examples

Example #1 Highlight search results

<?php
$pattern 
'(>[^<]*)('quotemeta($_GET['search']) .')';
$replacement '\\1<span class="search">\\2</span>';
$body eregi_replace($pattern$replacement$body);
?>

Notes

Note:

As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED notice. See the list of differences for help on converting to PCRE.

Tip

eregi_replace() is deprecated as of PHP 5.3.0. preg_replace() with the i (PCRE_CASELESS) modifier is the suggested alternative.
