Automatically Upload Images with PHP Directly from the URI

Stoimen — Fri, 10 Sep 2010 06:49:54 +0000

It is a simple task to upload images on the server with PHP using a simple web form. Than everything’s in the $_FILES array and after submitting the form the file’s on the server. By simply move_uploaded_file you can change its location on the server to the desired folder.

However is there a way to “upload” files without using a web form, but only by telling the PHP script where to find the image. First and most important the image should be web visible and accessible by HTTP.

The solution is quite easy – you can grab the file using file_get_contents, and than put it on the desired server folder with file_put_contents. Here’s some source:

$image = file_get_contents('http://www.example.com/image.jpg');
file_put_contents('/var/www/my.jpg', $image);

Extending the Case

You can go even further by downloading any kind of files with the same approach. What will be the case for an mp4 video is shown in the next example:

$video = file_get_contents('http://www.example.com/video.mp4');
file_put_contents('/var/www/my.mp4', $video);

Usage

This can be quite useful when trying to automate an remote upload process. In this case when somebody uploads an image on his site, you can duplicate this file on your server! However don’t forget the copyrights!

Flex 3 Custom DateChooser

stoimen — Sun, 01 Mar 2009 08:48:55 +0000

I searched so much about a custom DateChooser component in Flex 3, that I decided to make one by myself. My criteria is to have ComboBoxes for both months and years. I simply merged the ComboBox component with DateChooser and there is the beta release. Please fill free to comment and report any bugs or feature requests.

Flex 3 Custom Preloader

stoimen — Fri, 06 Feb 2009 06:26:33 +0000

Before to start I’ll put a link to my post with download and sample of a custom preloader you can use in your applications: /2009/02/25/flex-3-custom-preloader-download/

If there’s a problem with making a custom flex 3 preloader, there is the solution. The problem after that is to place it at the center of the stage. But there is a solution again. Just because the Application is not available yet, doesn’t mean that the preloader cannot be positioned correctly.

Just don’t forget to use the stage.width and height properties, as shown in the example, and use that after added on stage event is fired.

Look carefully at the example!

I recently posted a sample with free donwload of custom datechooser. The sample can be found on:
