Download Remote File
- by Abs
Hello all,
I have a function that will be passed in a link. The link is to a remote image. I thought I could just use the extension of the file in the URL to determine the type of image but some URLs won't have extensions in the URL. They probably just push headers to the browser and therefore I do not have an extension to parse from the URL.
How can I test if the URL has an extension and if not then read the headers to determine the file type?
Am I over complicating things here? Is there an easier way to do this? I am making use of Codeigniter maybe there is something already built in to do this?
All I really want to do is download an
image from a URL with the correct
extension.
This is what I have so far.
function get_image($image_link){
$remoteFile = $image_link;
$ext = ''; //some URLs might not have an extension
$file = fopen($remoteFile, "r");
if (!$file) {
return false;
}else{
$line = '';
while (!feof ($file)) {
$line .= fgets ($file, 4096);
}
$file_name = time().$ext;
file_put_contents($file_name, $line);
}
fclose($file);
}
Thanks all for any help
