Here's an autoload function that works both for normal classes as well as for namespaces.
Is there an easier way to do this for namespaces? set_include_path might do the job but it
didn't worked for me so I'll keep using my solution :D
general.php:
<?php
/**
* YES value
* @var int
*/
define('YES',1); //A 'YES' or 'NO' is doc friendly
/**
* NO value
* @var int
*/
define('NO',0);
/**
* Define wether SMARTY template engine is active
* @var int
*/
define('SMARTY_ENABLED',NO); //I use Smarty for some developments so I'll leave it
here
/**
* Define classes directory location
* @var string
*/
define('PHP_CLASSES_PATH','C:/Program
Files/Zend/Apache2/htdocs/project/php/classes'); // Set it to whatever path you like
/**
* Define namespaces location
* @var string
*/
define('PHP_NAMESPACES_PATH',PHP_CLASSES_PATH); //Same as PHP_CLASSES_PATH, set this to
whatever path you like, it's just an example ;)
/**
* If SMARTY is enabled the define the proper path
*/
if(SMARTY_ENABLED===YES){
define('SMARTY_DIR','C:/Program
Files/Zend/Apache2/htdocs/project/Smarty/libs');
}
/**
* Autoload function for classes
* Needs following constants to be set: SMARTY_ENABLED,YES,SMARTY_DIR, PHP_NAMESPACES_PATH and
PHP_CLASSES_PATH
* @param $class Class name, it is set automatically
* @throws Exception
*/
function __autoload($class){
$class = strtolower($class); //I assume all filenames are in lowercase, class name can be
ProjectConfig and the autoload function will look for the file projectconfig
if($class == 'smarty'){
if(SMARTY_ENABLED === YES){
require_once (SMARTY_DIR . DIRECTORY_SEPARATOR . "Smarty.class.php");
}
else{
throw new Exception('SMARTY is not enabled');
}
}
else{
if(strpos('\\',$class)){
$class = preg_replace('/\\/',DIRECTORY_SEPARATOR,$class); //Sometimes the OS
will not recognize namespaces separator as a directory separator
require_once (PHP_NAMESPACES_PATH . DIRECTORY_SEPARATOR . $class . ".php");
}
else{
require_once (PHP_CLASSES_PATH . DIRECTORY_SEPARATOR . $class . ".php");
}
}
}
?>
file.php:
<?php
require_once('./general.php');
use Something/Client; //Change '/' for '\'
$client = new Client();
$client2 = new Something/Client(); //Change '/' for '\'
?>
