Php Curl不适用于SMS API URL

Question

URL在浏览器中工作正常，但它不适用于Curl和php的file_get_contents功能。请帮我解决这个问题。

PHP代码：

<?php
$url="http://prygma.maxonlife.com/api/sendmsg.php?user=GORDSK&pass=G@nesh123&sender=GORDSK&phone=1234567890&text=TestSMSfortheday&priority=ndnd&stype=normal";
$ch = curl_init($url);
curl_exec($ch);
print_r(curl_getinfo($ch));
curl_close($ch);
?>
