trying to store data on external ipfs node via http api , ipfs.infura.io refusing my connection

Question

I'm trying to store data to ipfs via PHP, I use curl to communicate with API , it works fine on my local node, but I want to use an external node from infura.io

but for some reason, ipfs.infura.io is refusing my connection via php even a simple command like ... I've tried it on my localhost as well as a couple of servers

here is a simple endpoint that you can open in the browser and get the output

https://ipfs.infura.io:5001/api/v0/pin/add?arg=QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn

but when I try to open it via php i get

Failed to connect to ipfs.infura. io port 5001: Connection refused

or when using another method like file_get_contents

file_get_contents(ipfs.infura.io:5001/api/v0/pin/add?arg=QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn): failed to open stream: Connection refused

i've tried it on local host and multiple server , i get the same result even via ssh command line

any idea why is this happening ?

here is a simplified version n of my code

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL,"https://ipfs.infura.io:5001/api/v0/pin/add?arg=QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn");
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($curl, CURLOPT_FAILONERROR, true);
    $res = curl_exec($curl);
    if (curl_errno($curl)) {
        $error_msg = curl_error($curl);
        echo ('error ...');
        echo ($error_msg);
       exit();
    }

    curl_close($curl);
    echo($res);

In order to connect ipfs node, you need to have a client library. client libraries automatically format API responses to match the data types used in the programming language and also handles other specific communication rules.

In javascript,

import { create as ipfsHttpClient } from "ipfs-http-client";
const client = ipfsHttpClient("https://ipfs.infura.io:5001/api/v0");

then this client makes request:

const added = await client.add(file, {
        progress: (prog) => console.log(`received:${prog}`),

In php, you can use this package: https://github.com/cloutier/php-ipfs-api

Check this to interact with infura: https://github.com/digitalkaoz/php-ipfs-api

This library requires the cURL module:

$ sudo apt-get install php5-curl
$ composer require cloutier/php-ipfs-api
$ composer install

  $ export IPFS_API=http://somehost:5001/api/v0

to use this Driver from the commandline simply provide the option (or leave it away since its the default):

$ bin/php-ipfs version --driver=IPFS\\Driver\\Http
$ bin/php-ipfs version

Client this Driver is intended for programmatically usage:

$driver = $container[IPFS\Driver\Cli::class];
//$driver = $container[IPFS\Driver\Http::class];
$client = new IPFS\Client($driver);

$response = $client->execute((new \IPFS\Api\Basics())->version());

var_dump($response);
