is_integer()
(PHP 4, PHP 5, PHP 7)
is_int()的别名
描述
此函数是is_int()的别名函数。
using function : if(is_integer($_POST[mobile_number])){ return true; //// 0-9 }else{ echo "Wrong number"; return false; }
There is no difference, per se. is_integer() is an alias of is_int().
There are two different functions. But, the reason why is beyond the scope of this article!
Could someone explain me, why there are 2 different functions: is_int and is_integer?
