eregi_replace - Replace regular expression case insensitive

SYNOPSIS
string eregi_replace (string $pattern, string $replacement, string $string) DESCRIPTION
This function is identical to ereg_replace(3) 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
o $pattern - A POSIX extended regular expression. o $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; 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. o $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(3) is deprecated as of PHP 5.3.0. preg_replace(3) with the i ( PCRE_CASELESS) modifier is the suggested alternative.
