How to call different methods in one PHP file?

[Bruce W...1]

I'm a PHP newbie coming from experience with ASP.NET. I want to have a separate
PHP file to support each HTML PHP page. This would be the equivalent of an
ASP.NET code-behind file but using PHP.

For one page to do a variety of different things I need to call different
methods (or functions) in the PHP code file that is dedicated to this purpose.
How do you do this? How do you call just one method?

Thanks for your help.

I'm not entirely sure what you're asking, if you have a class you
have the choice of either instantiating it as an object and calling
the method on the object like so:

$object =& new ClassName($class_parameters_if_you_have_any);
$object->methodName();

Or if the class is composed of static (stand-alone) methods it can be
called as:

ClassName::methodName();

There is no signature.....

According to the parameters of the page.

If I call my PHP page with example.php?task=2 the code in example2.php
will lokk like that:
$task = (isset($_GET['task']) ? intval($_GET['task']) : 0;
switch ($task) [
case 1:
functionA();
break;
case 2:
functionB();
break;
default:
break;
}

It isn't good programming style to use one PHP file per HTML page. Classes
should be based on functionality, as should PHP files. If all your pages
were to do with a membership system then you should have a Member class with
methods appropriate

methods appropriate to that functionality.

If you've got a group of functions that perform similar actions you should
include them in a functions.member.inc.php file and include them where you
need them. You should group functions/methods by functionality rather than
per page as it will reduce the repetition element, imo.

That makes sense I guess, if the functions are used by more than one page.

That still doesn't answer my original question but thats okay.

I'm also trying to make sense out of the file names. In a system where every
file can be named whatever.php there needs to be some organization. So I was
going to have a codebehind file for each page named whatever.cb.php.

May I ask what are your file naming conventions? functions.member.inc.php is
one of them.

I tend to put my classes in a single file called class.name.php and place
them in a /classes directory on the site. I then usually have two other
files in the site root, globals.inc.php and common.inc.php. Common.inc.php
contains all the basic functions I use on multiple pages and also includes
globals.inc.php. Globals.inc.php is just a list of variables and constants
for the site that contains MySQL information, site URL and paths, etc. Every
PHP file on the site then includes common.inc.php, which in turn includes
globals.inc.php.

I don't use any external files for functions. If a function is required
across pages I write a class otherwise it sits in the actual page. I also
don't have any HTML in my PHP pages, they're pure PHP and all the template
stuff is in a collection of tpl.name.php files that the pages include as
necessary. Separating the design from the logic is a big time saver and big
bug reducer.

Going back to your original question...

To call a method from an included file you need to include it, instantiate
the class and then call the method;

require ("class.name.php");
$myclass = new FunkyClass;
$myclass->method_name ();

If the class was in the same PHP file you wouldn't need the require
statement.

If you wanted to call a function from an included file you need to include
it and call it;

require ("functions.member.php");
funky_function ();

And same again, if the function is in the same PHP file, no require
statement is needed.
