Question

以下PHP函数产生此错误：解析错误：语法错误，意外'（'，期待T_STRING或T_VARIABLE或'$'，在此行：throw new ( '' . 'Illigal name for service name "' . $name . '" is given' );

有谁知道什么是错的？

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

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

改变这个：

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

对此：

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

另外，通常你会在try catch块中抛出一个Exception：

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