How to run a PHP script
If you need to run a php-script in a terminal-session like putty, you can use this command:
mnt/ext/opt/apache/bin/php /path/to/some-php-script.php
Example running the Backup-Dump script from Mediawiki
mnt/ext/opt/apache/bin/php dumpBackup.php --full > /share/Vol2/Wiki-Backup/BWL/YYY-MM-DD.xml
Notice that this command was executed from the maintenace directory, where the php-file is located!
