split function is deprecated but still used

[Hugh Davenport]

http://php.net/manual/en/function.split.php

One example is htdocs/lib/mahara.php line 1046

According to the tip on PHP.net, split() will be replaced by explode() if using a string as a delimiter and by preg_split() if using regular expression

[Son Nguyen (ngson2000)]

Some deprecated functions should not be in the code.

1. Deprecated functions in Php 5.4: http://php.net/manual/en/migration54.deprecated.php
2. Deprecated features in Php 5.3: http://php.net/manual/en/migration53.deprecated.php

Should we check these as minaccept when committing a code?
