So what you actually want is file-level scope? Let's say it reuses the "private"
keyword:
<?php // strings.func.php
private function makeItSafe($text) {
// ...
}
function addHappy($text) {
return "Happy " . makeItSafe($text);
}
var_dump(function_exists("makeItSafe")); // true
?>
<?php // numbers.func.php
private function makeItSafe($number) {
// ...
}
function addOne($number) {
return makeItSafe($number) + 1;
}
var_dump(function_exists("makeItSafe")); // true
<?php // sub.php
require "strings.func.php";
require "numbers.func.php"; // no conflicts
echo addHappy("New Year");
var_dump(function_exists("addHappy")); // true
var_dump(function_exists("addOne")); // true
var_dump(function_exists("makeItSafe")); // false
?>
(note that if you literally want to avoid polluting the root namespace then you can use a namespace
for the "hidden" functions)
I'm going to go out on a limb here and say that the modules paradigm is not an appropriate
feature for PHP, but if you disagree with that strongly enough then check out the RFC process.

Having similarities with javascript is neither a good, nor a bad thing.
but implementing new features that can help using php with different programming paradigms is good.

Ok, here is an example
<?php // strings.func.php
function makeItSafe($text)
{
/// assume some proccess is going on here.
return $text;
}
function concat($t1, $t2)
{
return makeItSafe($t1) . makeItSafe($t2);
}
function addHappy($text)
{
return 'Happy ' . makeItSafe($text);
}
export {concat,addHappy}
<?php //main.php
import {concat as ct} from 'string.func.php';
echo(ct('Birthday','John'));
<?php //sub.php
import {addHappy} from 'string.func.php';
echo(addHappy('New Yeat'));
echo is_callable('makeItSafe'); /// returns false
in this way functions are easy to import when needed without the need to use include/require which
in return pollutes global scope.

So? If you don't want to use a class then don't use a class. But what else was
"Module" supposed to be in your example?
> more importantly, it's complicated,
That's right. But it's how Javascript modules work. You can't pick and choose which
parts of modules you keep and which you don't because everything is interconnected.
What would your version of strings.func.php look like?
> i don't necessarily want php to look like javascript.
Me neither. But if you say "I want modules like Javascript" then you're going to have
something that looks like Javascript.

"Modules" are a separate concept from functional programming.
PHP is not designed to be a functional language but you can still hammer in that screw using
closures and lambdas.
How about a more concrete example of what you want to be able to do with PHP but currently are not?

Hi requinix, your solution while it works but still uses classes under the hood and more
importantly, it's complicated, which goes against one of php's main strengths, it's
simplicity.
i don't necessarily want php to look like javascript. what i like to see is to have a more
functional programming friendly php.
