run code in 300+ PHP versions simultaneously
<?php class X {}; class Y implements Serializable{ }; $x = new X(); $y = new Y(); var_dump(serialize($x)); var_dump(serialize($y));
Output for git.master, git.master_jit, rfc.property-hooks
Deprecated: Y implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary) in /in/0HPo0 on line 5 Fatal error: Class Y contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (Serializable::serialize, Serializable::unserialize) in /in/0HPo0 on line 5
Process exited with code 255.
