PHP include

Hi everyone,

I'm not sure if it's a right place to ask, but I have nowhere else to go to

I'm trying to build a website in PHP and want to have some usefull functions in a separate file, so later I could just reuse then by including.
But, there seems to be a problem here:

file: test.php

PHP Code:



<?php 
function usefull_function1(){ 
 
echo"Some text"; 
 
} 
?>

file: index.php

PHP Code:



<?PHP 
include('test.php'); 
 
usefull_function1(); 
?>

once executed index.php shows an error:
Fatal error: Call to undefined function usefull_function1() in index.php on line 4

I juct don't understand why??? In any other programing languages an 'include' like directive just takes a premade code from a specific file and inserts it AS IS
Does PHP operate otherwise???

Thank you all in advance.

Easy mistake, just put your path in the include statment..
include("/var/www/htdocs/somedirectory/test.php");

syntax is incorrect:

http://us2.php.net/manual/en/function.require.php

Actually, no, the syntax is perfectly fine. If you're refering to the parentheses, they're not required, but you can still use them. They're only an issue when returning a value from a call to include().

I tried copying and pasting the given code into a couple of files in the same directory, and it ran perfectly for me, so the problem isn't there. It's probably a problem with your include_path. It probably just doesn't contain the directory where test.php is located.
