Which is the newer or more recommended use?

$a = (int)\"3 euros\";
         


        

Answer 1

This is not quite true, there is actually a difference between int and integer. Here a simple example:

//print_r('PHP version: '.phpversion().'
');
//PHP version: 5.5.23

$i = '1';

function testme(int $j){
  print_r ($j);
}
testme(intval($i));

This little portion of code will print an "E_RECOVERABLE_ERROR" since testme function is expecting 'int' and get 'integer' instead.
