Question

The PHP function below is producing this error: Parse error: syntax error, unexpected ‘(‘, expecting T_STRING or T_VARIABLE or ‘$’, on this line: throw new ( '' . 'Illigal name for service name "' . $name . '" is given' );

Does anyone know what’s wrong?

function registerService($name, $provider) {
    if (strlen( $name ) < 1) {
        Exception;
        throw new ( '' . 'Illigal name for service name "' . $name . '" is given' );
    }

    $this->_Services[$name] = $provider;
}

Thanks

Change this:

    Exception;
    throw new ( '' . 'Illigal name for service name "' . $name . '" is given' );

To this:

throw new Exception('Illegal name for service name "' .$name .'" is given' );

Also, normally you’d throw an Exception in a try catch block:

try {
    throw new Exception('Just testing');
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}
//Output: Caught exception: Just testing
