Can this code help to sanitize malicious code in user submit form?
function rex($string) {
$patterns = array();
$patterns[0] = '/=/i';
$patterns[1] = '/javascript:/i';
$replacements = array();
$replacements[0] = '';
$replacements[1] = '';
return preg_replace($patterns, $replacements, $string);
I have included htmlentities() to prevent XSS on client side, is all the code shown is safe enough to prevent attack?
