Php Download Html File From Url

2006-12-11: Sometimes linking directly to audio or video files can cause problems because the website isn't fast enough to support 'streaming' video playback on the fly. Or users may have trouble with videos in their browser, but no trouble when they access them from their desktop. Or perhaps you just want to invite the user to save a text file or an image, rather than displaying it in the browser window. It doesn't really matter what kind of file it is - the point is that the browser would normally display it directly, and you want to help the user save it to disk instead. The first and best solution is to use the Content-disposition: header, which tells the browser that regardless of the file's content type, the proper treatment is to save it to disk. This is the best solution because it requires no extra effort on the user's part. However, it does require that you have access to PHP, ASP.NET, Perl/CGI or another dynamic web programming solution.

Which in most cases means it can't be used with free hosting services. But for serious webmasters, it's the right way to go, and I'll discuss it in detail. The second technique, which works nearly as well, is simply to store your file inside a zip file. The vast majority of users today have either Windows XP or MacOS X, both of which include very friendly built-in handlers for zip files. Windows XP displays these as 'compressed folders' and makes it very easy for the user to launch files or extract them to disk. Empire Earth 1 Download Full Version Free.

Still, zip compression probably won't save any additional space when dealing with video and audio files, and there's a performance price - the user must wait for the file to be unzipped (or at least extracted) before it can be played back. So while zipfiles might be the only way for those who don't want to use PHP or a similar language, they definitely aren't the best way. Let's move on and look at how to do it the best way. Forcing Downloads With Content-disposition. The rest of this article assumes that your file is a video file.

Keep in mind that you can use exactly the same techniques for other file types. Just substitute your filename in place of movie.mpg. Those who understand know that the returns several 'headers' along with every object downloaded by the. The best known of these is Content-type:, which tells the browser what kind of file it is dealing with: a web page ( Content-type: text/html), a GIF image ( Content-type: image/gif), and so on. A lesser-known header, Content-disposition:, can be used to tell the browser what should be done with the file. By default, the browser will 'dispose' of the object by displaying it in the browser or launching an appropriate external player, whichever is appropriate. But when Content-disposition: is set to attachment; filename=movie.mpg, the browser instead displays a 'open, save or cancel' dialog box, inviting the user to save the file under the name movie.mpg.

The default may be to open the file in an external player, but that does not happen automatically, and the user is given a clear 'save' option in both major browsers. How can we take advantage of this? In PHP, it's simple. Instead of linking directly to the file as we normally would: See my MPEG movie We create a simple PHP 'page' that delivers the file to the browser for us.

Then we link to the.php file instead, and let it do the work of outputting the correct Content-disposition: and Content-type: headers, then the actual file. I put the word 'page' in quotes here for a reason! Although we'll use a file called movie.php, this PHP file won't be generating a page of HTML. It will be generating an MPEG movie - a different content type entirely.

$content = file_get_contents('?>Another way of resolving slowness issues is to use cURL or fsockopen. Bear in mind that contrary to the behavior of web browsers, file_get_contents doesn't return the result when the web page is fully downloaded (i.e. HTTP payload length = value of the.

PHP can do that, sending images, audio and video directly to the browser, as long as PHP code appears at the very beginning of the file and immediately sets the appropriate Content-type: header. Otherwise, PHP defaults to generating an HTML page. Here's the code for movie.php: NOTE: this file must contain only PHP code and nothing else. Ek Haseena Thi Serial Tone. No blank lines before or after. Blank lines before will cause PHP to default to Content-type: text/html. Blank lines after will be sent as additional 'garbage' data after the video, potentially causing problems.

This attribute is only used if the href attribute is set. The value of the attribute will be the name of the downloaded file. There are no restrictions on allowed values, and the browser will automatically detect the correct file extension and add it to the file (.img,.pdf,.txt,.html, etc.). If the value is omitted, the original filename is used.
