Previous Comments: ------------------------------------------------------------------------ [2021-11-08 17:33:42] requinix@php.net 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. https://wiki.php.net/rfc ------------------------------------------------------------------------ [2021-11-08 17:07:05] pooyaestakhry at gmail dot com > > i don't necessarily want php to look like javascript. > Me neither.

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. ------------------------------------------------------------------------ [2021-11-08 17:03:43] pooyaestakhry at gmail dot com 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. ------------------------------------------------------------------------ [2021-11-08 16:41:11] requinix@php.net > but still uses classes under the hood 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. > what i like to see is to have a more functional programming friendly php. "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? ------------------------------------------------------------------------ [2021-11-08 16:28:19] pooyaestakhry at gmail dot com 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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
