dynamic IF statement.

Anon

I'm making a site, where mysql makes multiple
function functions()
{
site html / content here
}

With the main if statement, to have

if($page=="something_update") { something_update();
}
The problem with this line, is I'd have to write it 10000 times, for a big site, and define every one.

I don't know howto put it, so the $page, which is the index.php?page=something_update
will use whatever the $page is, as the function..

Can't find it anywhere in my php book.

I think variable variables might solve your problem.

Hmm.
I don't know howto get it to be dynamic.

$page_call = "*";
$$page_call = "$page_call";

if($page=="$page_call") { $$page_call(); };

What would I put in the $Page_call for it to be anything?

Okie, I see what you mean now, I think you would want to use eval() for that. Something like this if I understand you correctly.

<?php

function function1() {
echo "this is function 1";
}

function function2() {
echo "this is function 2";
}

if ($page)
eval("{$page} ();");

echo "<a href='$PHP_SELF?page=function1'>Function 1</a>";
echo "<a href='$PHP_SELF?page=function2'>Function 2</a>";

You can eliminate the curly brackets around $page as long as you leave the space after it.

Anon

That doesn't make it dynamic.. I have to enter each page function in there.

what i'm trying to do is eliminate that

Anon

How would you know which function to enter in there when the time came to do so?

Anon

I guess I don't know what you mean then. Are you saying that you want the actual function to be dynamic ? Like you only want the page to have one function in it, and it needs to be the one that the user passes through the URL?
