I have a public object Let say X. defined in a config file. How could I use this object in a method within a class. I think when I globalize X in that method its looks within the class. :(
include('config.php'); //the objec X is defined here
class MyClass{
public foo(){
global $X; // I thing It is looking within the class
}
}
I have made a demo...I hope this is what you wanted.. global.php
<?php
$x=5;
?>
index.php
<?php
include('global.php');
class foo{
private $value;
function __construct(){
global $x;
$this->value=$x;
}
function show(){
return $this->value;
}
}
$a= new foo();
echo $a->show();
?>
This works for me:
class LemonSalesman {
public function advertise() {
echo 'Get your fresh lemons here!';
}
}
$LemonSalesman = new LemonSalesman();
class MyObject {
public function foo() {
global $LemonSalesman;
$LemonSalesman->advertise();
}
}
$MyObject = new MyObject();
$MyObject->foo();
Are you sure your $X object is global?
If you defined $x in your config file in this way:
<?php
$x = 'somevalue';
?>
then using the global in the function will work just fine. Alternately you could also use the global array to access the variable $GLOBALS['x'], however I'm not sure how common or suggested that is.
However, if you have your configuration variable defined inside a function or class then it would have to have a global there as well for example:
<?php
function loadConfig(){
// no global here means that $x is not global.
$x = 'somevalue';
}
<?
