Creating a simple socket

I'm completely new to PHP sockets and I'm gonna use them for one simple purpose at the moment: I want to pass information between a Cron Job and the net one, and since my host prevents me from using putenv, this is the best solution I found.

Reading the official documentation, this is what I tried to do:

$host = "localhost"; //or ssl://mydomain.com
$socket = fsockopen($host, 80, $no, $err,0);
if(!$err)
{
    var_dump(fputs($socket, "random text"));
    var_dump(filesize($socket));
    var_dump(fgets($socket, filesize($socket)));
    fclose($socket);
}

This is the output I get:

int(3)
NULL
bool(false)

So it seems that fput has success, but for some reason it does not actually write anything (same result with fwrite and fread.

UPDATE:

for anyone interested in that, I found out another solution which uses a completely different approach.

Now I just have to test it out; if it does not work for any reason, I'm gonna proceed with peakle's solution

Solution

you have some errors on your script, like: zero timeout in fsockopen, provide resource to filesize function, i fixed some them and if your server on localhost domain works fine it will be output correct response:

<?php
$host = 'localhost';
$socket = fsockopen($host, 80, $no, $err, 30);

if (!$err) {
    var_dump(fputs($socket, "random text"));

    while (!feof($socket)) {
        echo fgets($socket, 4096);
    }

    fclose($socket);
}
