Checking Contributions for PHP 5.3 Compatibility

You may have noticed the new dropdown box on the Contribution Add/Update page which asks about PHP 5.3 compatibility.

To determine whether your contribution is compatible, you need to check for the use of functions which are deprecated in PHP 5.3; here's a list:

http://php.net/manual/en/migration53.deprecated.php

The most likely offenders are:

* split/spliti
* ereg/ereg_replace/eregi/eregi_replace

If you can write your code in such a way as to not use these deprecated functions, users will have an easier time when their hoster upgrades. Thank you!
