$a['id'] = 124;
$b['id'] = '124';

if ($a['id'] == $b['id']) {}

In this case I want id`s are equals. How to properly compare string and int as int? Is there elegant way?

    @searcherforthetrueth Since you are using == instead of ===, PHP will automatically convert the type of the second value as necessary for comparison. What you are doing is fine. Commented Dec 7, 2018 at 4:55

Parse the string value to integer like this:

if($a['id'] == (int)$b['id']) {    
    // notice `(int)` which will make the '124' to int 124
}

Thank you, maybe is there another elegant way with a trick with php standard function something like compare('int', value1, value2)- maybe do you know function like array_reduce or something like these fictional examples for correct comparing two values?
Please just remove inner if condition.its not needed.
