How to compare string and int as int?

Question

$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?

Answer 1

Parse the string value to integer like this:

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