php exec question

[pkrtech]

I am using

[code]exec( 'wget http://www.test.com/run.php > /dev/null &' ); [/code]

to run a background process being called from a php page, it runs fine. However everytime it runs it places a empty run.php.1, run.php.2 ect ect. Now the script can run like 25 times an hour so thats alot of files I have to delete to clean up.

Is there some way to make it so it doesnt add the file ?

This will download the file once, then for each additional hit, will rewrite to that same file.
[code=php:0]
exec( 'wget -r http://www.test.com/run.php > /dev/null &' );
[/code]
