Custom function within parallelMap()?

[jeffbotw]

How to call custom php function?

<?php

require __DIR__ . '/vendor/autoload.php';

use function Amp\ParallelFunctions\parallelMap;
use function Amp\Promise\wait;


function myTestFunction($str){
    //returns test
    return substr($test, 0, -1); 
}

$responses = wait(parallelMap([
    'test1',
    'test2',
    'test3',
], function ($str) {
    return myTestFunction($strt);
}));


var_dump($responses);

Define your function in a file that's auto-loaded by Composer.

@kelunik

<?php
require 'vendor/autoload.php';

use function Amp\ParallelFunctions\parallelMap;
use function Amp\Promise\wait;

$arguments = ['argument1', 'argument2', 'argument3'];

$responses = wait(parallelMap($arguments, function ($arg) {
    // Call the custom function based on the argument
    if ($arg === 'argument1') {
        return customFunction1($arg);
    } elseif ($arg === 'argument2') {
        return customFunction2($arg);
    } elseif ($arg === 'argument3') {
        return customFunction3($arg);
    }
}));

create a auto load file that have following code

<?php


function customFunction1($arg) {
    // Simulate a time-consuming operation
    sleep(4);
    return "Result from customFunction1: $arg";
}

function customFunction2($arg) {
    // Simulate a time-consuming operation
    sleep(1);
    return "Result from customFunction2: $arg";
}

function customFunction3($arg) {
    // Simulate a time-consuming operation
    sleep(3);
    return "Result from customFunction3: $arg";
}

but it is waiting for customFunction1 output it is not parallel
