EXAMPLES
Example #1
Using get_class(3)
<?php
class foo {
function name()
{
echo "My name is " , get_class($this) , "
";
}
}
// create an object
$bar = new foo();
// external call
echo "Its name is " , get_class($bar) , "
";
// internal call
$bar->name();
?>
The above example will output:
Its name is foo
My name is foo
Example #2
Using get_class(3) in superclass
<?php
abstract class bar {
public function __construct()
{
var_dump(get_class($this));
var_dump(get_class());
}
}
class foo extends bar {
}
new foo;
?>
