How to mention ip port in random ip curl script - php

Question

I have a random IP script for curl but i don't know how to use port for same random script
function curl_get($kix)
{
$ips = array(
'85.10.230.132',
'88.198.242.9',
'88.198.242.10',
'88.198.242.11',
'88.198.242.12',
'88.198.242.13',
'88.198.242.14',
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $kix);
#curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_INTERFACE, $ips[rand(0, count($ips)-1)]);
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
$html = curl_exec($ch);
curl_close($ch);
return $html;
}
You can see here i have mentioned the ip but i dont know how to mention port for those ip's.
Thanks in advance !

If you have different ports per IP, you can associate the port to the IP with an associative array.
So for the following function I assume that you use PHP >= 7.0 and the following as format of our array.
array('IP'=>'Port');
We also CURLOPT_PORT to assign the alternative IP to connect with.
To quote the documentation:
CURLOPT_PORT: An alternative port number to connect to.
So back to your issue:
I use curl_setopt($ch, CURLOPT_PORT, $port); to assign the port we need to use.
I use array_rand($ips) to get a random key from the newly created associative array (The list of IP)
Finally I get its port with direct access to the array using $port = $ips[$randomIP];
So your function now looks like:
function curl_get($kix)
{
$ips = array(
'85.10.230.132' => '80',
'88.198.242.9' => '8080',
'88.198.242.10' => '5754',
'88.198.242.11' => '80',
'88.198.242.12' => '8888',
'88.198.242.13' => '8989',
'88.198.242.14' => '8080',
);
// We get a random key (IP)
$randomIP = array_rand($ips);
// We get the port according to the random key (IP)
$port = $ips[$randomIP];
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $kix);
#curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_INTERFACE, $randomIP);
// We set the alternative port with the following
curl_setopt($ch, CURLOPT_PORT, $port);
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
$html = curl_exec($ch);
curl_close($ch);
return $html;
}
