Cannot access data from external URL - php

Question

I tried to open an external url. It works fine in my local server. But when i moved to live server it showing time out error.
When i replaced the url by a url in the same domain ,it works fine.
allow_url_fopen is ON in the server.
<?php
if ($fp = fopen('https://www.google.com/', 'r')) {
$content = '';
// keep reading until there's nothing left
while ($line = fread($fp, 1024)) {
$content .= $line;
}
echo $content;
echo 'do something with the content here';
// ...
} else {
echo 'an error occured when trying to open the specified url';
}
?>
Updated
$curl_handle=curl_init();
curl_setopt($curl_handle,CURLOPT_URL,'https://www.google.co.in/');
curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2);
curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
$buffer = curl_exec($curl_handle);
curl_close($curl_handle);
if (empty($buffer)){
print "Nothing returned from url..<p>";
}
else{
print $buffer;
}
I tried cURL too. It returns "Nothing returned from url..". But it works fine in my local and demo server.

You should use curl to get data from third party URL.
please check the below link and example :
What is cURL in PHP?
Example :
$ch = curl_init();
$curlConfig = array(
CURLOPT_URL => "http://www.example.com/yourscript.php",
CURLOPT_POST => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POSTFIELDS => array(
'field1' => 'some date',
'field2' => 'some other data',
)
);
curl_setopt_array($ch, $curlConfig);
$result = curl_exec($ch);
curl_close($ch);
