)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.
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.
The modified string is returned. If no matches are found in
string, then it will be returned unchanged.
Example #1 Highlight search results
<?php
$pattern = '(>[^<]*)('. quotemeta($_GET['search']) .')';
$replacement = '\\1<span class="search">\\2</span>';
$body = eregi_replace($pattern, $replacement, $body);
?>
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_DEPRECATEDnotice. See the list of differences for help on converting to PCRE.
