eregi_replace
(PHP 4, PHP 5)
eregi_replace — Replace regular expression case insensitive
Description
This function is identical to ereg_replace() except that this ignores case distinction when matching alphabetic characters.
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.
