i'm trying to get strip/add slashes function working but its coming up with an error on this line...but im sure im doing the right thing...does anyone know where im going wrong please or even if this is possible

 

$function = "add"; // or strip
$value = {$function}slashes($value);

 

thank you destramic

$function = 'add';
if (function_exists($function . 'slashes')) {
  $value = call_user_func($function . 'slashes', $value);
}

sorry im now having an error...i was firstly just setting $function as strip but when setting it in function argument as below im getting the error:

Warning: Missing argument 2 for add_strip_slashes_deep()

strange

<?php
function add_strip_slashes_deep($value, $function)
{
if (function_exists($function . "slashes"))
{
	if (get_magic_quotes_gpc() && 
	    is_array($value))
	{
		$value = array_map("add_strip_slashes_deep", $value);
	}
	else if (is_string($value))
	{
		$value = call_user_func($function . 'slashes', $value);
	}
}
else
{
	echo "An error has occurred.<br />\n";
}

    return $value;	
}


// Example
$array = array("f\\'oo", "b\\'ar", array("fo\\'o", "b\\'ar"));
$array = add_strip_slashes_deep($array, "strip");

// Output
print_r($array);
?>

You could replace:

 

$value = array_map("add_strip_slashes_deep", $value);

 

With:

 

$value = array_map("add_strip_slashes_deep", $value, array_fill(0, sizeof($value), $function));

 

or just:

 

foreach($value as &$element)
{
$element = add_strip_slashes_deep($element, $function);
}

i don't think that is the problem...its not noticing the argument $function when set to strip
