Error on global.php

[Gajeel]

I am receiving an error on RevCMS hosted on a webhost.

Here is the error

Parse error: syntax error, unexpected T_STRING, expecting T_CONSTANT_ENCAPSED_STRING or '(' in /home/playsafe/public_html/global.php on line 22

And here is the information on the webhost, just incase anyone would answer I should update my PHP version.

And global.php on line 22:

use Revolution as Rev;

Any help please? I am currently making PrivExt so I need help.

Awts. Then I should use localhost for now. But thanks. I thought it's alright as long it is 5.x
