Description
string
get_parent_class ( [mixed obj] )
If obj is an object, returns the name of the
parent class of the class of which obj is an
instance.
If obj is a string, returns the name of the parent
class of the class with that name. This functionality was added in PHP
4.0.5.
Note:
Since PHP 5, obj is optional if called from the
object's method.
If called without parameter outside object, this function returns
FALSE (or NULL with a warning before PHP 5.1.0).
Example 1. Using get_parent_class()
<?php
class dad {
function dad()
{
// implements some logic
}
}
class child extends dad {
function child()
{
echo "I'm " , get_parent_class($this) , "'s son\n";
}
}
class child2 extends dad {
function child2()
{
echo "I'm " , get_parent_class('child2') , "'s son too\n";
}
}
$foo = new child();
$bar = new child2();
?>
|
The above example will output: I'm dad's son
I'm dad's son too |
