How to start session with php code - php

Question

I would like to send request to server. I am using this code for it
$data=[..];
$header=[
"Accept-language: en-US,en;q=0.5",
"Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
"Connection: keep-alive",
"Host: www.rvvi.cz",
"Referer: https://www.rvvi.cz/riv?s=rozsirene-vyhledavani",
"Upgrade-Insecure_Requests:1",
"User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:59.0) Gecko/2010",
"Cookie: PHPSESSID=4ck9tc3vm4prgfubnjvutilgd2",
"Content-type: application/x-www-form-urlencoded"
];
$url = "https://www.rvvi.cz/riv";
$query = http_build_query($data);
$ch=curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST,strlen($query));
curl_setopt($ch,CURLOPT_POSTFIELDS,$query);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
$page=curl_exec($ch);
echo($page);
but problem is with PHPSESSID in header. To access that, i have to manually go to this server with my browser ( this that probably start my SESSION ), copy PHPSESSID and paste it into my script. But, i would like to make this script automatic. I need to to active them from my server without using browser or copying something.
Is there any way how can i start this session just with my php code?

$curl = curl_init( 'https://httpbin.org/post' );
curl_setopt( $curl, CURLOPT_POST, true );
curl_setopt( $curl, CURLOPT_POSTFIELDS, array( 'field1' => 'some data', 'field2' => 'some more data' ) );
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
$response = curl_exec( $curl );
curl_close( $curl );
