When submitting a new node that has a free tagging category sassociated,

unitag.module,v 1.1.2.26 2008/01/23 16:52:40

throws error:

Fatal error: Call to undefined function: array_intersect_key() in ..../sites/all/modules/unitag/unitag.module on line 713

I'm on php 4.3.11, drupal 5.7 (recently upgraded from 5.6). This used to work before, not sure what introduced this behavior since the function array_intersect_key has been in unitag from the start it seems.
Php 4 is still a supported release for drupal so I think modules shouldn't use php5 functions like array_intersect_key.

Appreciating this useful module, thanks for your help

just happen to me as well,
was editing an existing content, in this case video, and add a few tags. Upon save the same error as above was showing.

Fatal error: Call to undefined function: array_intersect_key() in /home/.../modules/unitag/unitag.module on line 713

Can anybody share why this happens and how to fix it. Until than I have to stop using that module. Thanks for reading.

I use right now:

Drupal 5.3
MySQL database 4.1.22
PHP 4.4.4
Unicode library PHP Mbstring Extension
Web server Apache/1.3.37 (Unix) mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 FrontPage/5.0.2.2635.SR1.2 mod_ssl/2.8.28 OpenSSL/0.9.7a PHP-CGI/0.1b

Your problem is php4. The unfound function is only present in php5 or greater.

See here for a possible solution:

Seeing as to how nobody should really be using PHP 4, I'm going to won't fix this. I have, however, added a note on the project page mentioning the workaround suggested by lutegrass.
