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.

Return Values

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

$pattern 
'(>[^<]*)('quotemeta($_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_DEPRECATED notice. See the list of differences for help on converting to PCRE.
