PHP cURL function is not working on specific site - php

Question

I am new to PHP and trying to use cURL function to fetch the view of a page, but I am unable to fetch for particularly www.zomato.com, while all other websites are working fine using this code.
<?php
set_time_limit(0);
function getSslPage($url) {
$ch = curl_init();
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE);
curl_setopt($ch, CURLOPT_CAINFO, $_SERVER['DOCUMENT_ROOT']."/mypro/cacert.pem");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_REFERER, $url);
//curl_setopt($ch, CURLOPT_PORT, 44455);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12');
$result = curl_exec($ch);
echo curl_error($ch);
echo curl_errno($ch);
curl_close($ch);
return $result;
}
ECHO getcwd();
$a=getSslPage("https://www.zomato.com/ncr/open-house-connaught-place-new-delhi/");
echo ($a);
?>
I get error no.- 056 when trying to use this code.
