Why doesnt work the fsockopen if my server called the file? - php

Question

I need little help..
We have a test code which use fsockopen. Code:
<?php
//require_once "../common.php";
$url = "https://xxxxx/xxxx/fsockopen_called_file.php";
$close = true;
echo "<pre>";
error_log("\n\n");
trigger_error("1. fsockopen url meghivasa: ".$url);
$result = call_url($url, $close);
trigger_error("2. eredmény: ".var_export($result, true)."\n\n");
function call_url($url, $close = TRUE) {
$user_agent = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.93 Safari/537.36";
$parts = parse_url($url);
if (#$parts["scheme"] === "https" && (!#$parts["port"] || $parts["port"] == 80)) {
$parts["port"] = 443;
$parts["scheme"] = "ssl";
}
$out = "GET ".$parts["path"]." HTTP/1.1\r\n";
$out.= "Host: ".$parts["host"]."\r\n";
$out.= "User-Agent: ".$user_agent."\r\n";
$out.= "Content-Length: 0\r\n";
if ($close) { $out.= "Connection: Close\r\n"; }
$out.= "\r\n";
$fsock_url = ($parts["scheme"] !== "http"? ($parts["scheme"]."://") : "").$parts["host"];
$fp = fsockopen($fsock_url, isset($parts["port"])? $parts["port"] : 80, $errno, $errstr, 30);
fwrite($fp, $out);
$result = "";
//Ha a kapcsolatot lezárjuk, akkor nem várjuk meg a választ.
if (!$close) {
while (!feof($fp)) {
$result .= fgets($fp, 128);
}
}
fclose($fp);
if (is_bool($fp) && !$fp && !$errno) {
//Az fsockopen false értékkel tért vissza, és nincs az errno változóban hibakód.
$errno = 1;
$errstr = "Nem lehetett a szerverhez kapcsolódni: ".$url." => ".$fsock_url;
}
return ["errno" => $errno, "errstr" => $errstr, "result" => $result];
}
My problem is that the file(fsockopen_called_file.php) that the code calls does not appear in the access log.
accesslog:
x.x.x.x - [19/Jun/2022:20:20:32 +0200] "GET /xxx/fsockopen.php HTTP/1.1" 200 4890 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/102.0.0.0 Safari/537.36"
Thats it. fsockopen_called_file.php file doesnt apper. It's like doesnt work.
Server info:
Ubuntu 20.04
Apache 2.4.54-1+ubuntu20.04.1+deb.sury.org+1

Does anyone have any ideas that can help me?
