How to get the progress status of the copy function in PHP?
You'll need to write your own copy function. First check the file size through a HTTP HEAD request, for example with this solution:
http://php.net/manual/en/function.filesize.php#92462
Then do this to fetch the file:
$remote = fopen('remote-file', 'r');$local = fopen('local-file', 'w');$read_bytes = 0;while(!feof($remote)) { $buffer = fread($remote, 2048); fwrite($local, $buffer); $read_bytes += 2048; //Use $filesize as calculated earlier to get the progress percentage $progress = min(100, 100 * $read_bytes / $filesize); //you'll need some way to send $progress to the browser. //maybe save it to a file and then let an Ajax call check it?}fclose($remote);fclose($local);
