1.2.434. Exception Order

When catching exception, the most specialized exceptions must be in the early catch, and the most general exceptions must be in the later catch. Otherwise, the general catches intercept the exception, and the more specialized will not be read.

<?php

class A extends \Exception {}
class B extends A {}

try {
    throw new A();
}
catch(A $a1) { }
catch(B $b2 ) {
    // Never reached, as previous Catch is catching the early worm
}

?>
