user functions

[Reimar Bauer]

I am a bit confused by writing or using my user functions.

The only way I know at the moment to call my own functions is to put them in
one file with the main program.

this example comes from http://de.php.net/manual/de/functions.php
<?php

function foo($foo, $bar = "bar")
{
echo $foo.$bar;
}

echo foo("foo");
//gives: foobar

echo foo("foo","bar2");
//gives foobar2

?>

I would prefer one file one function. How could I do this or is this
absolutly wrong to do it this way. How did php know where to look for a
user function.

regards
Reimar

Go look up include(), require() etc.

I usually put my functions in a separate file which I include.

<?php // foo-function.inc.php
function foo($foo, $bar = 'bar') {
echo $foo, $bar;
}
?>
Then I include this file in my scripts. For instance, index.php could be

<?php // index.php
require_once 'foo-function.inc.php';

echo foo('foo');
// gives foobar

echo foo('foo', 'bar2');
// fives foobar2
?>
