bool property_exists ( mixed class, string property )

As opposed with isset(),
property_exists() returns TRUE even if the property
has the value NULL.
Parameters
- class
The class name or an object of the class to test for
- property
The name of the property
Return Values
Returns TRUE if the property exists, FALSE if it doesn't exist or
NULL in case of an error.
Examples
Example 388. A property_exists() example
<?php
class myClass {
public $mine;
private $xpto;
static function test() {
var_dump(property_exists('myClass', 'xpto')); // true, it can be accessed from here
}
}
var_dump(property_exists('myClass', 'mine')); //true
var_dump(property_exists(new myClass, 'mine')); //true
var_dump(property_exists('myClass', 'xpto')); //false, isn't public
myClass::test();
?>
