Running a PHP script in the background

Shaggy_FF

Hi, I am new to php scripting.

Here is my situation:

I have an swf file which calls the getUrl command.
getURL("script1.php", "_blank", "POST");

this calls a php file i have on my server called script1.php. This script modifies the contents of several *.txt files, and needs to be called to do this because swf files do not have the capability to write any data to a server, and need to call a server-side script that will write the data for them.

the problem is that i dont know how to run this script in the background. See, when my swf file calls the script, i want the server to run it, and write thge data accordingly, but i dont want a white (blank) page to show up, or any sort of page period. When script1.php is called from the swf file i want the viewer of the webpage to be able to continue viewing their page uninterrupted. The reasoning behind this, is that at times this swf file will call the above code { getURL("script1.php", "_blank", "POST"); } several times.

As I am relatively new to php scripting, i will need a detailed explanation of what needs to be done. (perhaps there is some sort of command i can run at the beginning of my php script that will make it so that the server tells the client not to open a browser window)

i think your problem is actually with flash's getURL in this case and not php. php code is server side therefore there are no functions or methods to tell the client not to open a browser.

i dont know flash but maybe there is an alternate function that can just call a script without displaying the output.

Hi, this is on a related note to my previous post. Is there a way for a php script to remove a specific cached file. Here's my situation: My swf file now calls a php script to run on the server. My previous dilemma has been resolved, however... the problem is the file m.txt that my php script is modifying gets cached on the clients computer. Because this file is modified several dozen times a day the clients computer ends up using an outdated cached version of m.txt rather than the servers version.

Does anyone have any thoughts on how i can resolve this issue. I thought perhaps the php script could remove the cached file from the clients computer when the php script modifies the servers file (m.txt).

any help would be appreciated

if it was a php script that the client was viewing you can send headers telling their browser not to cache the file, but there is no way to make their browser delete anything from their cache.
