Why does my php script give this error - "Call to undefined function: hash()"

Last updated: 02/07/2012

This may be that your server is running php 4, and needs to be running php 5. On some hosting providers, you can choose which version you want. You can try adding this .htaccess file to your document root to fix:

AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php

This forces the server to use php5 when running .php scripts. Not all hosting providers support this, so you'll have to experiment or check with them.
