PHP 5.3 generates slew of errors

[craigmj]

Under PHP 5.3 the ereg() method has been deprecated, and a number of other features are changed.

The attached diff allows Piwik to install and run under 5.3. It primarily fixes the deprecated issues in the code, BUT NOT in the Unit Tests: these currently generate a range of warnings about depracation.

Therefore this diff is a starting point, and SHOULD BE CHECKED since in some places it is not immediately obvious that the ereg -> preg replacement is trivial.

In theory, the diff is backwards-compatible, but I've only tested under 5.3, so am unsure about this.

Note too that I've not changed the ereg calls in

libs/PclZip/pclzip.lib.php libs/UserAgentParser/UserAgentParser.php

Since these are libraries, I have left them, and they don't appear to cause a problem on my instance yet (which I've only just installed and started playing with).

Patch to get Piwik running under PHP 5.3

[vipsoft]

craigmj: thanks for the patch. I've extended the changes to libs and tests, and reviewed/applied fixes for the other backward incompatibilities and deprecated functions (e.g., split and magic methods).

Notes:

• I didn't apply the change to config/global.ini.php as it isn't backwards compatible with php 5.2.x
• I reworked the fix for libs/Event/Dispatcher.php to handle the header & footer callbacks.
• the patch to libs/Smarty/plugins/functions.fetch.php comes from Smarty SVN
• the patches to Zend will be reviewed again in #497

(In [1287]) fixes #845 - php 5.3 backward incompatibilities and deprecated functionality; quick fixes #851 - unit tests; also fix redirect error in Installation when deleting existing tables

craigmj & vipsoft, good stuff - Piwik has been fast to be 5.3 compatible.

[matt]

by the way, vipsoft, please let me know when you think it is best to release 0.4.2 to address these changes.

[vipsoft]

(In [1293]) refs #845 - update simpletest (from 1.0.1beta to 1.0.1); apply changes for php 5.3 (i.e., deprecated functionality); change ordering of unit tests (all_tests.php)

[vipsoft]

re-opening: regression with php 5.2.x; all_tests.php broken in trunk

[vipsoft]

Not a regression.
