PHP and "modularity"

[Anon]

Having come from a C++ and VB environment, I am used to placing common functions in a module, and then calling them from that module as needed.

Does PHP support this modular concept? IOW, if I develop a function to deal with, say, formatting of phone numbers, is there any way to place this function in a "PHP" module and call it as necessary from that module?

Right now, I must resort to placing the function in every .php file where it is needed. Seems silly to me.

it this wasnt possible, php would suck! 🙂
just keep all your functions in a file, say functions.inc.php (current convention i believe) then include that file into every page that needs its functions:

<? include 'functions.inc.php' ?>

you can also use require, include_once or require_once. check the manual for more info

Thanks, paul.

One thing I like about this forum : You can always get answers rather quickly instead of beating your head against the "programing" wall for hours (or days -- or weeks).

I will try out your solution. And it looks good to me. And it should eliminate a lot of redundant code I have written in the last few weeks!

Thanks again for your input, and to all others here who have taken the time to answer my mundane questions. Well, this is a PHP learning community, right?

Cheers!

Use OO-PHP to encapsulate and modularise functions.

Here is an example:

class MyFunc {

var $avar;

function MyFunc($msg) {
$this->avar = $msg;
}

function writeMessage() {
echo ($this->avar);
}

}

$test = new MyFunc("G'day, Mate!");
$test->writeMessage();

i definately agree in using classes. i use them extensively myself. but if the class is required on multiple pages, youll want to put it in a file that can be used by the pages that need it.
