Creating a function????

[Anon]

Could anyone explain in layman terms how I can use the PHP function command.

I have got a script which I want to use several times for different scenarios. For each one of these only 1 variable in the script needs to change - therefore creating a function out of the script makes sense.

I've got a little way to understanding it, but can anyone help me along, and correct me where I'm wrong.

To create a function I do this:

<?php
function my_reusable_function($my_one_changing_variable)
{
//Insert the full script here
}
?>

To run the script with my changing variable I put:

<?php
my_reusable_function(the_variable_that_will_change);
?>

If I want to save my functions in a different directory to the scripts that reference them, how do I get the script to know where the function I want to use is?????

eg If I store my functions in mysite.com/php/functions

and my script that references it is in
mysite.com/scripts/myfirstscript.php

What do I need to insert within the script to find the function?????

Some different way to create a function...

I saw that the you are putting the variable to be change in entry in your function...

Thats good...

But dont forgot to return the value.

function xyz($change_var)
{
...
return($change_var);
}

when you call thise function

$variable_to_change=xyz($variable_to_change);

This is one way to call the function.

the second way is to declare the variable global in your function.

function xyz();
{
static $change_var;
}

In this case, no return is needed.

You can use $change_var every where in your PhP module.

To include a saved function, in the begin of your module, you can use :

require(/.../.../klm.php);

For information, you can also download the PhP manual at : www.php.net

you might want to try

require_once("/path/to/functionfile.inc");

and

include_one("/path/to/functionfile.inc");

rather than just require() and include() to make sure it never gets included twice.
