calling functions

gr3gg0r

If i have a function in a file (file.php), and i want to call that function in a seperate file (calling.php), how would i do that if they were in the same directory? Different firectories?
THanks!

Hey,

Here is what you will need to do. First include the file that has all the functions you want. This can be done either by same directory or different ones. I usually setup my structure by having all of my includes in one folder named includes. Thus looking something like this:
Main directory
|--includes
|--images
|--common
|---|--css
|---|--logos
|---|--includes

<?php
// calling.php
// SAME DIRECTORY CALLING FROM MAIN DIRECTORY
include_once("file.php");

CallFunction();
?>

Different directories:

<?php
// calling.php
// DIFFERENT DIRECTORY CALLING FROM MAIN DIRECTORY
include_once("includes/file.php");

CallFunction();
?>

Getting to have the file attached to the file being processed is really the main purpose of the include(), include_once(), require(), require_once() functions. Read up on them at: http://us3.php.net/manual/en/language.control-structures.php

Take care and keep coding!

// file.php ---

<?php

function foo() {
   do_something();
}

?>

// script.php

<?php

include'/path/to/file.php';

$bar=foo();

?>

Note that if "file.php" does anything besides set up some functions, it could adversely affect "script.php", as everything in "file.php" is [man]include[/man]d() in "script.php" (output, other variables, etc., etc.)
