There are some functions not working properly with namespaces
<?php
namespace MyApp;
class Fruit {}
class Apple extends Fruit {}
$apple = new Apple();
$name = 'Apple';
var_dump (is_subclass_of($apple, 'Fruit'));
var_dump (is_a($apple, 'Apple'));
var_dump (new $name);
How can I make this compatible with both php 5.3 and php < 5.3 with no namespace support ? is_subclass_of and is_a are not working like this !
<?php
namespace MyApp;
class Fruit {}
class Apple extends Fruit {}
$apple = new Apple();
$name = 'MyApp\Apple';
var_dump (is_subclass_of($apple, 'MyApp\Fruit'));
var_dump (is_a($apple, 'MyApp\Apple'));
var_dump (new $name);
You need to fully qualify your namespace name in functions that take a class name as a string instead of as a bareword. Classes as barewords are resolved at runtime. Here's the PHP manual on namespace resolution, and here's a page with examples using strings to fully qualify namespaces.
(Also note the single quotes to prevent backslash munching.)
