autoload class

The __autoload() magic function is used to dynamically load classes. Whenever PHP encounters a non-existent class, it will first call the __autoload() function, and only then declare an error. This can be used to load classes on-the-fly. error_reporting (E_ALL); if (version_compare(phpversion(), '5.1.0', '<') == true) { die ('PHP5.1 Only'); } // Constants: define ('DIRSEP', DIRECTORY_SEPARATOR); // Get site path $site_path = realpath(dirname(__FILE__) . DIRSEP . '..' . DIRSEP) . DIRSEP; define ('site_path', $site_path); $registry = new Registry; // Set some data $registry->set ('name', 'Don'); // Get data, using get() echo $registry->get ('name'); // Get data, using array access echo $registry['name'] function __autoload($className) { // Assume that all class files are located in the same dir and subdirs $fname = str_replace('::', DIRECTORY_SEPARATOR, $className) .

MySql Slow Queries

MySQL has a slow query log which can be enabled if you want to identify the queries that are causing problems for a website or application. Checking slow queries is one of the most important steps in optimizing and tuning mysql. This article shows how to identify those 'slow queries' that need special attention and proper optimization. First let’s check on the server if slow query logging is enabled on MySql. On Windows cd c:\xampp\mysql\bin bin>mysqladmin var | find "log_slow_queries" On linux bin>mysqladmin var |grep log_slow_queries Enable the slow query log MySQL prior to 5.1.0 requires a change to the MySQL my.cnf file and a restart in order to log slow queries. From MySQL 5.1.0 you can apparantly change this dynamically without having to restart. Too make the change permanent, you could add the following lines under the [mysqld] section of your my.ini or my.cnf configuration file: >vi /etc/my.cnf [mysqld] # Activate the Slow Q...
