How to add multiple url in "CURLOPT_URL =" - php

Question

I am trying to get response from multiple url using API call and change color based on response. Problem is I want to get response from multiple url at the same time. But the program only can take the last url from the array.
I also tried using array for multiple url and looping but didn't work. Below is my code.
<?php
// An array of URLs to make requests to
$urls = array(
'https://example.com/v1/objects/services?service=1',
'https://example.com/v1/objects/services?service=2'
);
// Create a new cURL multi handle
$mh = curl_multi_init();
$username = "root";
$password = "apipass";
$headers = array(
'Accept: application/json',
'X-HTTP-Method-Override: GET'
// Add each URL to the cURL multi handle
foreach ($urls as $i => $url) {
$ch[$i] = curl_init();
curl_setopt_array($ch[$i], array(
CURLOPT_URL => $url,
CURLOPT_HTTPHEADER => $headers,
CURLOPT_USERPWD => $username . ":" . $password,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYHOST => 0,
CURLOPT_SSL_VERIFYPEER => 0
));
curl_multi_add_handle($mh, $ch[$i]);
}
// Execute the cURL multi handle
do {
$status = curl_multi_exec($mh, $active);
} while ($status === CURLM_CALL_MULTI_PERFORM || $active);
// Get the responses from each handle
foreach ($urls as $i => $url) {
$response[$i] = curl_multi_getcontent($ch[$i]);
}
// Close the cURL multi handle and each individual handle
foreach ($urls as $i => $url) {
curl_multi_remove_handle($mh, $ch[$i]);
}
curl_multi_close($mh);
foreach ($response as $i => $response) {
// check response and change color based on it
if(strpos($response, "Unreachable") !== false) {
$color[$i] = 'red';
// success response
} else {
$color[$i] = 'green';
}
}
print $status;
print $color[$i];
?>
