I want to lazy load class but with no success
<?php
class Employee{
function __autoload($class){
require_once($class);
}
function display(){
$obj = new employeeModel();
$obj->printSomthing();
}
}
Now when I make this
function display(){
require_once('emplpyeeModel.php');
$obj = new employeeModel();
$obj->printSomthing();
}
It works but I want to lazy load the class.
__autoload is a standalone function not a method of a class. Your code should look like this:
<?php
class Employee{
function display(){
$obj = new employeeModel();
$obj->printSomthing();
}
}
function __autoload($class) {
require_once($class.'.php');
}
function display(){
$obj = new Employee();
$obj->printSomthing();
}
UPDATE
Example taken from the php manual:
<?php
function __autoload($class_name) {
include $class_name . '.php';
}
$obj = new MyClass1();
$obj2 = new MyClass2();
?>
__autoload at all
spl_autoload_register. Imagine this code is on a huge website with many criss-crossing dependencies on pages. What if someone has already used __autoload on an app that goes untested that happens to include the file where he is defining the other __autoload.
Change Employee a bit:
class Employee {
public static function __autoload($class) {
//_once is not needed because this is only called once per class anyway,
//unless it fails.
require $class;
}
/* Other methods Omitted */
}
spl_autoload_register('Employee::__autoload');
First if all it's better to use spl_autoload_register() (check the note in php's manual for autoloading).
Then back to your problem; only if the display() function is in the same directory as the employeeModel this will work. Otherwise, use absolute paths (see also include() and include_path setting
