I want to make a decision whether the program is an integer
Because no matter whether it is a negative number or a positive number, it is not an integer//So try to get a piece of code done. Master

------Solution--------------------

Echo (GetType ($num) = = "integer")? " Integer ":" Is not an integer ";

------Solution--------------------
if (Preg_match ('/^[-+]?\d+$/')) echo ' Integer ';

$a = 50;
return $a = = ($a <<0);
