Global variables PHP Gets the code for the global variable

Copy the Code code as follows:

function Cleanglobal ($global _array, $arg, $specialchars = true, $default = null) {
if (Key_exists ($arg, $global _array) && $global _array[$arg]! = null && $global _array[$arg]! = "") {
if ($specialchars) {
Return Htmlspecialchars ($global _array[$arg]);
} else {
return $global _array[$arg];
}
} else {
return $default;
}
}

The above describes the global variables PHP gets the global variables of the code, including the contents of the global variables, I hope the PHP tutorial interested in a friend helpful.
