Previous versions incompatibility
For previous version than 5.3.3 there is a big incompatibility. The methods with the same name as the class name used by the namespace are not anymore considered as the class constructor. This change does not affect the classes those do not use namespaces.
1 2 3 4 5 6 7 8 9 10 | <?php namespace Foo; class Bar { public function Bar() { // Act as constructor in PHP 5.3.0-5.3.2 // Act as a regular method in PHP 5.3.3 } } |
This change does not have impact in migrations from PHP 5.2.x, due to namespaces were introduced from PHP 5.3.0.
