Question

Which is the right way to implement php exception (try{}catch(){}) in a foreach loop that looks like this:

foreach ($apis as $api)
{                 
     $api = '_'.$api;
     $searchResults[$api] = $this->$api($parameters);
}

I want to implement the php exceptions for if one of the $this->api(); returns an error message, than catch it and do a if inside the catch to display the right message for the error message returned.

Edit:
Also, when capturing the error and if the error message is 1 (for example) is it a good way to do:

$searchResults['api'] = $this->_api($parameters);

so it tries to do the function again and see if this time it brings valid data?

Answer 1

foreach ($apis as $api)
{                 
     $api = '_'.$api;
     try {
         $searchResults[$api] = $this->$api($parameters);
     }
     catch(ParameterException $e) {
         // parameterexception handling here
         echo "A ParameterException was thrown";
     }
     catch(Exception $e) {
         // All other exceptions
         echo "Some other Exception was thrown";
     }
}

You can differentiate between more Exception-Types as well.
