----
if using pattern modifier "i" with an empty pattern string then this empty pattern matches
any string.
example:
<?
$string = "abcdefg";
$pattern = '';
echo (@preg_match($pattern,$string)) ? "TRUE" : "FALSE" ; // returns FALSE
$pattern = '%%i';
echo (@preg_match($pattern,$string)) ? "TRUE" : "FALSE" ; // returns TRUE
?>
