note 103606 added to language.namespaces

for example, if you use a lot of .php files (once per class) you need to know that require() a lot of files will slow down consistently the page load so you can use namespaces + autoload to implement package-specific initialization handlers i used this to put an entire package (lot of classes) in one php file !!! please note you can't use this as-is but you need to adapt it to your project the file __init.php is placed inside every namespace/folder you want to load there you can startup your namespace, check for environment, debugging, or as i do, you can merge all the package in one php file and require it to load other classes too. <?php class Loader { // here we store the already-initialized namespaces private static $loadedNamespaces = array(); static function loadClass($className) { // we assume the class AAA\BBB\CCC is placed in /AAA/BBB/CCC.php $className = str_replace(array('/', '\\'), \DIRECTORY_SEPARATOR, $className); // we get the namespace parts $namespaces = explode(\DIRECTORY_SEPARATOR, $className); unset($namespaces[sizeof($namespaces)-1]); // the last item is the classname // now we loops over namespaces $current=""; foreach($namespaces as $namepart) { // we chain $namepart to parent namespace string $current.='\\' . $namepart; // skip if the namespace is already initialized if(in_array($current, self::$loadedNamespaces)) continue; // wow, we got a namespace to load, so: $fnload = $current . \DIRECTORY_SEPARATOR . "__init.php"; if(file_exists($fnload)) require($fnload); // then we flag the namespace as already-loaded self::$loadedNamespaces[] = $current; } // we build the filename to require $load = $className . ".php"; // check for file existence !file_exists($load) ?: require($load); // return true if class is loaded return class_exists($className, false); } static function register() { spl_autoload_register("Loader::loadClass"); } static function unregister() { spl_autoload_unregister("Loader::loadClass"); } } Loader::register(); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 87.11.150.180 ---- Manual Page -- http://www.php.net/manual/en/language.namespaces.php Edit -- https://master.php.net/note/edit/103606 Del: integrated -- https://master.php.net/note/delete/103606/integrated Del: useless -- https://master.php.net/note/delete/103606/useless Del: bad code -- https://master.php.net/note/delete/103606/bad+code Del: spam -- https://master.php.net/note/delete/103606/spam Del: non-english -- https://master.php.net/note/delete/103606/non-english Del: in docs -- https://master.php.net/note/delete/103606/in+docs Del: other reasons-- https://master.php.net/note/delete/103606 Reject -- https://master.php.net/note/reject/103606 Search -- https://master.php.net/manage/user-notes.php
