GD module

Anon

Hi,

My host is running php 4.0.3pl1 and when i asked they said they had the GD module installed.

But everytime I try to use a script with gd fuctions i get "Fatal error: Call to undefined function: imagecreate() in test.php on line 19"

I noticed in the docs for imagecreate() on php.net they have $img = @imagecreate(); The @ sign being important. What exactly does that mean? When i try that it doesnt give a fatal error but it doesnt work.

Does anyone have a test script I can try to run to see if it's installed or working. And should I contact their support to ask (tech support there is kinda mean >=( ).

Also I read somewhere php 4 had built in GD support. So is there something else I could be doing wrong? All other php scripts seem to work fine (that i've tried).

The "@" sign means that nothing is sent back to the browser.. All output is discarded..

This is very important when working width images, because images are in binare, text is in ascii.. those two cant be mixed, as they would be if an error occoured..

Call phpinfo() on a page. It will tell you exactly what is installed.

I called phpinfo and didnt see anything about gd...searched the page for GD and nothing showed up. They told me specifically it was installed but i'm guessing they could have made a mistake. Is there anything else i could do before I contact them?

Thanks for all the help btw =)

Check the top section "Configure Command". It should have the option "--with-gd". Somewhere below there should be a section "gd" with info like

GD Support enabled
GD Version between 1.3 and 1.6.1
FreeType Support enabled
FreeType Linkage with TTF library
GIF Support enabled

Since you don't see it, it is safe to say your sys admins are wrong.
