Hi everyone!

Im getting stuck with a piece of code that is include below . =( . It may be easy for you to realize the idea for this code ,just a variable validator for 2 types 'Array" and 'String' . Could anyone here help me to make it run and improve it ?

Thank in advance ^.

function input_var(&$var) {

if(gettype($var) == 'array')
{
	reset($var);
	while(list($key,$val)=each($var))
	{
		$var[$key] = input_var($val);
	}
}
else if(gettype($var) == 'string')
{
	$var = trim($var);
	$var = strip_tags($var);
	$var = addslashes($var);
}
return $var;
}

{
	function cleanup($arg)
	{
		$arg = trim($arg);
		$arg = strip_tags($arg);
		$arg = addslashes($arg);
		return $arg; 
	}

if (is_string($var)) {$var = cleanup($var);}
if (is_array($var)) {$var = array_map('cleanup', $var);}

return $var;
}

Hi Thank for reply , the following code seem to not work with the array type. =)

<?
$testString = "This is a String''";
$testArray = array("Key1" => "Value1" , "Key2" => "Value2");
function input_var($var) 
{ 
    function cleanup($arg) 
    { 
        $arg = trim($arg); 
        $arg = strip_tags($arg); 
        $arg = addslashes($arg); 
        return $arg;  

    } 

if (is_string($var)) {$var = cleanup($var);} 
if (is_array($var)) {$var = array_map('cleanup', $var);} 

return $var; 
}  

$output1 = input_var($testString);
echo $output1;
$output2 = input_var($testArray);
echo $output2[0];
?>

And it output the error

This is a String\'\'
Fatal error: Cannot redeclare cleanup() (previously declared in f:\localhost\www\test.php:6) in f:\localhost\www\test.php on line 6

move the cleanup() function definiton outside of the scope of the input_var() function.
