I have to crawl some values from a website. Should I use curl for that or file_get_contents ??
I am getting some warning with file_get_contents at my localhost .
Any help will be appreciated

If you have basic requirements, I would favor file_get_contents. If you need to set headers, and request method etc... I would recommend using curl.
In your case, I think file_get_contents is enough.
Alternatively, you can use file which returns an array of lines from the retrieved file. It works with locally accessible files, and also with remote urls. I often find it more convenient to loop over an array of lines, than to deal with the whole file in one block - so this might be your best option.
<?php
foreach(file('http://example.com/the-file.ext') as $line){
// do something with $line
}
?>

I think Curl is more preferable, as compared to file_get_contents as you can set headers, request methods like POST or GET, follow redirection etc. So, curl will be advisble
<?php
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$data = curl_exec($ch);
curl_close($ch);
echo $data;
?>
