php

Hi,

I don’t understand regular expressions at all – I will make an effort to
learn about them one day, but I need a solution today. I want to use the
__autoload function, but not for all my class only those that finish in
‘Controller’. So for instance,

‘ErrorController’ should load ‘errorcontroller.inc.php’
‘IndexController’ should load ‘indexcontroller.inc.php’
‘FooBar’ should NOT load anything whatsoever.

Can you help me write an __autoload function please??

Have you even tried it? This is not hard, and doesn't need to use any
regular expressions at all.

We're not here to write code for you, we're here to help when you have
problems. Try it, see how far you get and send us the code if/when you
get stuck.

Unless you want to hire me to do it. My rates are pretty reasonable
for simple stuff like this.

Problem solved:
function __autoload($c) {
$m = array();
preg_match('/(?:^[A-Z][a-z]+)Controller/', $c, $m);
if (count($m)) {
require_once(realpath(FS_CONTROLLER . '/' . strtolower($m[0]) .
'.inc.php'));
}
}

However (perhaps a more appropriate question), do you think there is an
easier/better way to do this??

See, that wasn't so hard was it!!

Personally I'd have gone with something more like this...

function __autoload($class)
{
if (substr($class, -10) == 'Controller')
{
// No need for realpath here, it's not doing anything useful
// The _once is probably redundant too, but it may be required
// depending on how your code is arranged.
require FS_CONTROLLER.'/'.strtolower($class).'.inc.php';
}
}

....but there's always more than one solution.

I'd just like to add spl autoload is friendlier since __autoload can
only be defined once.

Please keep the conversation on the list!

If you're going to use regular expressions you need to read the manual
to understand how they work. There's a whole section of the manual
that covers this - go read it to understand what the ^ means!

Awesome website. You should be a veritable RegEx guru after reading that
site for one day. (It'll also tell you what the ^ and $ means, as well
as that (? group).
