php in_array check for multiple values

It depend on how many values to check using in_array. If more than two, better way is loops through array and runs an in_array of it on the checking array. Returns true once something is found, else it returns false.

$main_array = array(1,2,3,4,5);
$check_value = array(1,3,6,8);

foreach ($check_value as $value) {

        if (in_array($value, $main_array)) {
             return true;
	     return false;

If only two, probably can use if:

	if(in_array('foo',$arg) && in_array('bar',$arg)){
	    //both of them are in $arg
	if(in_array('foo',$arg) || in_array('bar',$arg)){
	    //at least one of them are in $arg
