How to Try Catch in symfony

Question

Situation:

//trollCommand.php
[...]
foreach ($trolltypes as $type) { //$type=={"Frost","RandomBroken","Forest"}
    try {
        $output->writeln($type);
        $troll={"get".$type."TrollType"}();
        $output->writeln("TEST 1");
        $troll->__load();
        $output->writeln("TEST 2");
    } catch (EntityNotFoundException $e) {
        $output->writeln("WARNING: TROLL ENTITY DOES NOT EXIST.");
        continue;
    }
    $output->writeln("TROLLING");
    do_something_with_troll($troll);
}

getFrostTrollType loads ok, getForestTrollType should be loaded ok too, but before that, it is a problem, getRandomBrokenTrollType() deliberately does not exist, and then I see message in console:

 Frost
 Test 1
 Test 2
 TROLLING
 RandomBroken
 Test 1
 [Doctrine\ORM\EntityNotFoundException]  
 Entity was not found. 
 //[EXIT FROM SCRIPT]
 troll@troll-machine ~/trollSandbox/ $ _

it should be: WARNING: TROLL ENTITY DOES NOT EXIST. and then continue; but it does not happen

How to check existing of a object's method?

Answer 1

if you're trying to catch any exception, you should use a backslash before "Exception".

E.g.:

try{
    //do stuff here
}
catch(\Exception $e){
    error_log($e->getMessage());
}

If you don't use a backslash, the exception won't be caught. This is due to how namespaces are used in PHP / Symfony.

Answer 2

the Exception thrown by Doctrine is called Doctrine\ORM\EntityNotFoundException and you are catching EntityNotFoundException.

Thats a difference, the namespace matters.

to debug this, catch Exception instead and observe the type of the actual exception. then replace it.
