PHP curl questions - php

Question

<?php
ini_set('display_errors',1);
$url = 'www.google.com.my';
$header = true;
$returntransfer = true;
$connecttimeout = 3;
$timeout = 60;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, $returntransfer);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $connecttimeout);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
$execute = curl_exec($ch);
$info = curl_getinfo($ch);
header('Content-Type: text/plain');
echo $execute;
echo "\n\ncurl_getinfo() said:\n", str_repeat('-', 31 + strlen($url)), "\n";
foreach ($info as $label => $value)
{
printf("%-30s %s\n", $label, $value);
}
echo str_repeat('-', 31 + strlen($url));
?>
Here is my questions:
(1) I want to test the web services using PHP curl. Am I missing something based from the above code?
(2) If I have 2 URLs, should I use curl_setopt or curl_multi_init?
I really hope that someone will answer my questions.

It's a simultaneous requests:
$ch_1 = curl_init('http://url.one.com/');
$ch_2 = curl_init('http://url.two.com/');
curl_setopt($ch_1, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch_2, CURLOPT_RETURNTRANSFER, true);
// build the multi-curl handle, adding both $ch
$mh = curl_multi_init();
curl_multi_add_handle($mh, $ch_1);
curl_multi_add_handle($mh, $ch_2);
// execute all queries simultaneously, and continue when all are complete
$running = null;
do {
curl_multi_exec($mh, $running);
} while ($running);
// all of our requests are done, we can now access the results
$response_1 = curl_multi_getcontent($ch_1);
$response_2 = curl_multi_getcontent($ch_2);
echo "$response_1 $response_2"; // same output as first example
