Showing image before PHP 100% done

Anon

Hi,

I have an image I want to display in an HTML table, the table being in my PHP file. I want the image to show as soon as the PHP file is called from an HTML form, and I want the image displayed at the top of the page (so I have put it at the top of my PHP file).

In other words, the image should be displayed in the browser before the PHP code is done processing (i.e. it is displayed while the PHP is being processed, instead of waiting for it to finish processing and then display).

As it is now, the image doesn't display until the PHP file has been 100% processed.

How can I achieve this?

Thanks.

You can try to use output buffering to acheive what you want. But, it is going to be heavily dependant on the web server you are using and the browser the client is using. In short, it is a difficult thing to acheive. You might have better luck using frames and having a bit of client side scripting to update the top frame with the image while the bottom frame is doing the php script....

Thanks for you reply.

I've read up on output buffering, and it seems to me that you can only send header lines, not body content.

I've tried it in my script, and so far, no success.

It was to my understanding that the PHP decoder (server) combs through everything first and foremost without any interruption... then the HTML (client) gets to do their work. If it were any other way the server might be reading something that the client has already interpretted.
