[misson]

Are you looking for variable functions? Other than that, any function that takes a callback (such as array_map) could be used to indirectly call a function. Is this just a puzzle or do you have a use in mind?

Did you write your code in MS Word, by any chance? The smart quotes it generates won't work for PHP. The smart caps look weird, but won't cause problems with the sample you posted. Use a text editor or an IDE to code. When you post code, put it in "

" or "[php]" tags to separate it from the rest of your post.

You've also got an errant ";" after your function declaration.  Here's what your code looks like after corrections and with indentation to improve readabiliy:
[php]$POINTER = 'rebelbar'; 

function rebelbar($what_bar) {
    echo "not just rebelbar, $what_bar rebelbar.\n";
}[/php]

Maybe you missed misson’s link to variable functions, so just in case, here you go:

<?php

$what_bar = 'your bar';
$POINTER = 'rebelbar'; 

$POINTER($what_bar);  // This calls function rebelbar()

function rebelbar($what_bar) {
    echo "not just rebelbar, $what_bar rebelbar.\n";
}  

?>

Best bet Zyreen, is think about getting a PHP IDE, this will syntax check your code for you. There's BluMentals' Rapid PHP or PHP Designer. They do syntax check and display syntax colors.....they're not extremely expensive and do the job

Here are the links, if you're interested in these 2 things.....

@zyreena

We usually don`t close the posts, as somebody migth need to add something, or add precision. We only close them went there is a clear misconduct toward the rules.
