I would like to use Guzzle to check if a remote file exists.
This is an example of how I am currently checking:
/**
* @return boolean
*/
function exists()
{
// By default get_headers uses a GET request to fetch the headers.
// Send a HEAD request instead
stream_context_set_default(
array(
'http' => array(
'method' => 'HEAD'
)
)
);
// Get the file headers
$file_headers = @get_headers($this->file);
// Check file headers for 404
if($file_headers[0] == 'HTTP/1.1 404 Not Found')
return false; // File not available.
return true; // File is available!
}
However, since I'm already using Guzzle elsewhere, I'd think I could make this prettier and more readable.
Am I right in thinking that? How would I accomplish that?
I did manage to find part of the answer in the docs. Guzzle - Request Methods
Combined with a gist that has a similar function, that checks for 404 status.
/**
* @return boolean
*/
function exists()
{
$client = new GuzzleHttp\Client();
try {
$client->head($this->file);
return true;
} catch (GuzzleHttp\Exception\ClientException $e) {
return false;
}
}
