Welcome to Findnerd. Today we are going to discuss the return types in php which is improved in PHP7. In php 7 you can set the data type for the return value of the
function. You need to set the declare(strict_types=1) in the file top.
<?php
declare(strict_types=1);
function userCal(int num1, int num2) : int{
if(num2==0){
return 999;
}else{
return ($num1/$num2);
}
}
$data = userCal(90,2);
$data = userCal(4,3);
?>
In above example we have set the strict typing mode. We created a function which should be return the integer type value. We called this function twice. In second
call, we passed two integer which we produce the float value so it will return the error of return type
