Non blocking functions PHP
<p>I have a project in wich a user uploads an image through a form and the server does some thumbnails. The thumbnailing is very slow so I thought that doing the image resizing with a non-blocking function could be a good solution. I mean: the server process the form (wich have more fields) gives the "ok" feedback to the user and then calls the thumbnailing function. How can I do that?</p>

<p>Thanks in advance</p>
