Programming pleasure is priceless

Hello.

Today I found a problem in Zend Framework and his class autoloader, where an class_exists function call fires the Zend Framework autoloader. The function has an option to ignore the autoloader, but any class that I need loaded by Zend_Loader will return false.

Then, if I call class_exists without disable autoloader, I got an file not exists PHP warning, that’s why Zend_Loader doesn’t check if the file exists, just include.

The trick is change Zend/Loader.php to check if file exists before include, and this must be wrote in loadFile method.

    public static function loadFile($filename, $dirs = null, $once = false)
    {
        self::_securityCheck($filename);

        /**
         * Search in provided directories, as well as include_path
         */
        $incPath = false;
        if (!empty($dirs) && (is_array($dirs) || is_string($dirs))) {
            if (is_array($dirs)) {
                $dirs = implode(PATH_SEPARATOR, $dirs);
            }
            $incPath = get_include_path();
            set_include_path($dirs . PATH_SEPARATOR . $incPath);
        }

        /**
         * Try finding for the plain filename in the include_path.
         */
        if (!self::fileExists($filename)) {
            return false;
        }

        if ($once) {
            include_once $filename;
        } else {
            include $filename;
        }

        /**
         * If searching in directories, reset include_path
         */
        if ($incPath) {
            set_include_path($incPath);
        }

        return true;
    }

    public static function fileExists ($filename) {
        $paths = explode(PATH_SEPARATOR, get_include_path());
        foreach ($paths as $path) {
            if (file_exists($path . DIRECTORY_SEPARATOR . $filename)) {
                return true;
            }
        }
        return false;
    }

Bye.
