Can't use ipc from apache (Pipeline)

[jonathan-rodan]

Very simple script. (NOTE, the function getRandomString just creates a random string, its not important)

The sender.php:

<?php

function getRandomString($valid_chars, $length) {
     // start with an empty random string
    $random_string = "";

    // count the number of chars in the valid chars string so we know how many choices we have
    $num_valid_chars = strlen($valid_chars);

    // repeat the steps until we've created a string of the right length
    for ($i = 0; $i < $length; $i++) {
         // pick a random number from 1 up to the number of valid chars
         $random_pick = mt_rand(1, $num_valid_chars);

        // take the random character out of the string of valid chars
        // subtract 1 from $random_pick because strings are indexed starting at 0, and we started picking at 1
        $random_char = $valid_chars[$random_pick-1];

        // add the randomly-chosen char onto the end of our string so far
        $random_string .= $random_char;
    }

    // return our finished random string
    return $random_string;
}

$type = ZMQ::SOCKET_PUSH;
$p1 = ($_SERVER['argv'])?'cli':'web').'->'.getRandomString(isset($_SERVER['argv'])?'cli':'web'), 25);
$p2 = getRandomString('qwertyuiopasdfghjklzxcvbnm,1234567890', 500);
$context = new ZMQContext();
$socket = new ZMQSocket($context, $type)
$socket->connect(ipc://mytest.ipc);

$success = $socket->send($p1, ZMQ::MODE_SNDMORE);
$success &= $socket->send('', ZMQ::MODE_SNDMORE);
$success &= $socket->send($p2);

echo $success ? 'YAY  :)' : 'FAIL :(';

receiver.php

<?php
$type = ZMQ::SOCKET_PUSH;
$context = new ZMQContext();
$socket = new ZMQSocket($context, $type)
$socket->bind(ipc://mytest.ipc);
while(true){
    echo $socket->recv();
    echo $socket->recv();
    echo '->msg('.strlen($socket->recv()).')';
}

How to test.

run the receiver.php on the console.

run the sender.php on the console (you will see "YAY")
look at the receiver and it will have: "cli->lciciclciclliclccilcilcil(500)"

open the sender using apache (you will see "YAY" on the browser)
look at the receiver and it will have: "cli->lciciclciclliclccilcilcil(500)" //NOTHING WILL BE RECEIVED
^^^^ERROR^^^^

modify the scripts to use tcp (bind to tcp://*:5555 and connect to tcp://localhost:5555)

(repeat test)

run the receiver.php on the console.

run the sender.php on the console (you will see "YAY")
look at the receiver and it will have: "cli->lciciclciclliclccilcilcil(500)"

open the sender using apache (you will see "YAY" on the browser)
look at the receiver and it will have: "web->wbeebwbebwbebbewbbwewebwb(500)"

Mi mistake, apache and cli use a different folder to create the "file" that's used for the connection.
to solve use the absolute path. (in this case it can be "ipc:///tmp/mytest.ipc")

thanks for posting the solution jonathan-rodan!
this made my day
