Symfony – Standard API for Logging Using __callStatic

Last year I wrote an article on how to write a simple, standard logging class for Symfony (http://melikedev.com/2010/08/25/symfony-standard-api-for-logging/). This article will demonstrate how do to the same functionality in only a few lines of code using __callStatic(). For more info on __callStatic() check out http://melikedev.com/2011/10/31/php-__callstatic-method-overloading/

Before:

// located @ /lib/MyCustom/Api/Log.php
class MyCustom_Api_Log
{
    /**
     * Wrapper method for getting a symfony logger object
     *
     * @return object
     */
    public static function getLogger()
    {
        return sfContext::getInstance()->getLogger();
    }

    /**
     * Wrapper method for logging debug message
     *
     * @param string $message
     */
     public static function logDebug($message)
     {
         self::getLogger()->debug($message);
     }
    /**
     * Wrapper method for logging an error
     *
     * @param string $message
     */
     public static function logError($message)
     {
         self::getLogger()->err($message);
     }
}

// Example Usage
MyCustom_Api_Log::logError('Oh noes something went wrong');

After:

// located @ /lib/MyCustom/Api/Log.php
class MyCustom_Api_Log
{
    /**
     * Wrapper method for getting a symfony logger object
     *
     * @return object
     */
    public static function getLogger()
    {
        return sfContext::getInstance()->getLogger();
    }

    /**
     * Magic method for logging all supported log levels
     *
     * @param string
     * @param array
     */
     public static function __callStatic($level, $params)
     {
         // Only concerned with message at this time
         // However any number of params can be passed in
         $message = shift($params);

        self::getLogger()->$level($message);
     }
}

// All these calls are made to __callStatic, so no need for individual methods
MyCustom_Api_Log::err(array('Oh noes something went wrong'));
MyCustom_Api_Log::warn(array('Oh noes something went wrong'));
MyCustom_Api_Log::notice(array('Oh noes something went wrong'));
