kmaid Posted February 2, 2009 Share Posted February 2, 2009 Hi I am making a validation function which will strip any dangerus code from an array or string. The problem is when i create a 2D array it screws up function cleanInput($Data) { $Data = mysql_real_escape_string(stripslashes($Data)); $search = array( '@<script[^>]*?>.*?</script>@si', // Strip out javascript '@<[\/\!]*?[^<>]*?>@si', // Strip out HTML tags '@<style[^>]*?>.*?</style>@siU', // Strip style tags properly '@<![\s\S]*?--[ \t\n\r]*>@'); // Strip multi-line comments return preg_replace($search, '', $Data); } function libStripInputSlashes($Data) { if (is_array($Data)) { foreach($Data as $var=>$val) { $output[$var] = cleanInput($val); } } else { return cleanInput($Data); } return $output; } $Data = libStripInputSlashes(array(array('<HTML> \' REALINPUT', '<HTML> \' REALINPUT', '<HTML> \' REALINPUT', '<HTML> \' REALINPUT', '<HTML> \' REALINPUT','<HTML> \' REALINPUT'),array('<HTML> \' REALINPUT', '<HTML> \' REALINPUT', '<HTML> \' REALINPUT', '<HTML> \' REALINPUT', '<HTML> \' REALINPUT','<HTML> \' REALINPUT'))); Echo $Data; Any ideas how I could fix this?

MadTechie Posted February 2, 2009 Share Posted February 2, 2009 try this <?php function libStripInputSlashes($Data) { if (is_array($Data)) { foreach($Data as $var=>$val) { $output[$var] = libStripInputSlashes($val); } }else{ return cleanInput($Data); } return $output; } ?> Quote Link to comment Share on other sites More sharing options...
printf Posted February 2, 2009 Share Posted February 2, 2009 This will handle deep array structures without using recursion... function libStripInputSlashes ( $global ) { while ( list ( $n, $v ) = each ( $global ) ) { foreach ( $v AS $name => $value ) { if ( is_array ( $value ) ) { $global[] =& $global[$n][$name]; } else { $global[$n][$name] = cleanInput ( $value ); } } } return $global; } Quote Link to comment Share on other sites More sharing options...
