Hi all,
Is there any way to auto load a class without using __autoload() function?
As I want to load some classes under different paths, and that caused
redeclare of __autoload function.
a lot of people / frameworks, etc. define their own class loading mechanism
in userspace. heres a simple example,
function _autoload($class) {
include(STD_CLASS_PATH . "/$class.php");
if(!class_exists($class)) {
trigger_error("unable to load class $class.", E_USER_NOTICE);
return false;
} else
return true;
}

that's what I do too.. personally I use _ (underscores) in PHP like .
(periods) in Java to map objects to folders/files..
function __autoload($class) {
if(file_exists( SOME_BASE_DIR . parse_class_name($class) )) {
include_once SOME_BASE_DIR . parse_class_name($class);
} else {
#your error here
}
}
function parse_class_name( $classname ) {
return strtolower( str_replace('_', DIRECTORY_SEPARATOR, $classname) .
'.php' );
}
so:
<?php
$http_handler = new http_handler;
?>
would autoload
SOME_BASE_DIR/http/handler.php
whilst
<?php
$atom_parser = new atom_parser;
?>
would autoload
SOME_BASE_DIR/atom/parser.php
keeps my files all nice and organised and saves me writing map's :)
