How can I handle the warning of file get contents function in PHP

Question

I wrote a PHP code like this

$site="http://www.google.com";
$content = file_get_content($site);
echo $content;

But when I remove "http://" from $site I get the following warning:

Warning: file_get_contents(www.google.com) [function.file-get-contents]: failed to open stream:

I tried try and catch but it didn't work.

Hello @kartik,

This is fairly simple:

if (!$data = file_get_contents("http://www.google.com")) {
      $error = error_get_last();
      echo "HTTP request failed. Error was: " . $error['message'];
} else {
      echo "Everything went better than expected";
}

I found this after experimenting with the try/catch from @enobrev above, but this allows for less lengthy (and IMO, more readable) code. We simply use error_get_last to get the text of the last error, and file_get_contents returns false on failure, so a simple "if" can catch that.

Thank you!!
