[2.7] CakePHP on PHP7

[davidsteinsland]

• Warning about srand wanting an integer, got string:

https://github.com/cakephp/cakephp/blob/2.7/lib/Cake/Utility/Security.php#L190

// Warning (2): srand() expects parameter 1 to be integer, string given
srand(Configure::read('Security.cipherSeed'));

This should be cast to int, no?

• Sessions:
  I have a basic DatabaseSession configuration.
  Warning (4096): session_regenerate_id(): Failed to create(read) session ID: user (path: /var/lib/php/sessions)

CakeSession::renew() - APP/Vendor/cakephp/cakephp/lib/Cake/Model/Datasource/CakeSession.php, line 756
SessionComponent::renew() - APP/Vendor/cakephp/cakephp/lib/Cake/Controller/Component/SessionComponent.php, line 150
AuthComponent::login() - APP/Vendor/cakephp/cakephp/lib/Cake/Controller/Component/AuthComponent.php, line 612

• Warning (2): session_write_close(): Session callback expects true/false return value in [Vendor/cakephp/cakephp/lib/Cake/Network/CakeResponse.php, line 1462]

Fixed by casting return values of DatabaseSession::write() to bool. The return value was model->save().

Is CakePHP 2.7 even tested on PHP 7 ... ?

@davidsteinsland As you can see from the travis files, only 2.8+ is PHP7 compatible.
Please upgrade to that if you need PHP7 compatibility.

Please also see http://book.cakephp.org/2.0/en/appendices/2-8-migration-guide.html#php7-compatibility

[davidsteinsland]

No, I'm not upgrading to a non-stable RC version in our production environments.

No it is not. One of the goals for 2.8 is to resolve PHP7 compatibility issues. The 2.8 release is API stable, and we're hoping that people using 2.x and PHP7 try it out in non-production setups and help us flush out any remaining issues.
