Edit report at https://bugs.php.net/bug.php?id=81599&edit=1 ID: 81599 Comment by: pooyaestakhry at gmail dot com Reported by: pooyaestakhry at gmail dot com Summary: adding the ability of modular import and export just like modern javascript Status: Feedback Type: Feature/Change Request Package: *General Issues Operating System: All PHP Version: Irrelevant Block user comment: N Private report: N New Comment: 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.

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. ------------------------------------------------------------------------ [2021-11-08 13:59:23] requinix@php.net (don't mind the syntax error) ------------------------------------------------------------------------ [2021-11-08 13:59:00] requinix@php.net You can already do this. <?php // strings.func.php $Module = get_class(new class { public function whatami() { echo "This is Module\n"; } }); $otherModule = function() use ($Module) { return new $Module(); }; return [ "Module" => $Module, "otherModule" => $otherModule ]; ?> and <?php list["Module" => $Module, "otherModule" => $otherModule] = require "strings.func.php"; $otherModule()->whatami(); ?> But why would you want to, given that PHP is architecturally, technically, and philosophically completely different from Javascript? ------------------------------------------------------------------------ [2021-11-08 13:09:41] pooyaestakhry at gmail dot com Description: ------------ PHP is mostly known as a procedural/OOP language.adding the ability to import and export modules like functions, variables and constants would mean that doors of functional programming would open up to those us who love php but are not a fan of oop. Test script: --------------- import {Module,otherModule as other} from dirname(__dir__,1).'/strings.func.php' ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81599&edit=1
