how to Access multiple URL at once in Curl PHP ?

$urls = array(
    'http://example.com/api1',
    'http://example.com/api2',
    'http://example.com/api3'
);

$curl_handles = array();

// create cURL handles for each URL
foreach ($urls as $url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $curl_handles[] = $ch;
}

// create a multi-handle to execute multiple requests in parallel
$multi_handle = curl_multi_init();

// add the cURL handles to the multi-handle
foreach ($curl_handles as $ch) {
    curl_multi_add_handle($multi_handle, $ch);
}

// execute the requests in parallel
$running = null;
do {
    curl_multi_exec($multi_handle, $running);
} while ($running > 0);

// process the responses
foreach ($curl_handles as $ch) {
    $response = curl_multi_getcontent($ch);
    // process the response for each URL
    echo $response;
    curl_multi_remove_handle($multi_handle, $ch);
    curl_close($ch);
}

// close the multi-handle
curl_multi_close($multi_handle);
