As far as I know, you can't. Create a function in your page controller class that returns the result of your php code, then place $FunctionName in the template

You can use StuM's answer if you know what your doing, otherwise you could use an iframe linking to the php script, BUT iframes are the devil, so I'd suggest going with StuM's answer.

In mysite/code/Page.php, if you've created it. If not, create one with the following:

<?php

class Page extends SiteTree {
static $db = array();
static $has_one = array();
}

class Page_Controller extends ContentController {
function init() {
parent::init();
}

function MyCustomPHPCode()
{
return 'blah blah blah';
}
}

save it as mysite/code/Page.php

then place $MyCustomFunction in your template

I think that's the correct way to achieve it, I'm a SS n00b still and that's how I've been doing it

you may have to run yoursite/db/build?flush=1 to get it working

Sorry, I put you wrong above, the template variable should be the same as the function name ($MyCustomPHPCode)

I just tried placing php code in the template myself, and it did work(although printed before the html started), so maybe something else is broken

try placing

Director::set_environment_type("dev");

in mysite/_config.php and see if that gives you any hints
