> Hi there.

> I've got a script that's calling another PHP script which creates a

> Simple enough.

> The thing is, the TAR archive is around 178 MB, so it's kinda on the
big side.
> 
> So, I have a simple question.
> 
> Currently, I am building the command to tar the files, and calling it 
> like this:
> 
> $cmd = "php -q /some/other/directory/maketar,php &";
> if( system($cmd) === false){
>   die( "was not able to call the TAR building script");
> }
> else{
>   // do other stuff, like copy it and extract it
> }
> 
> So, my question is...is the above if then construct sufficient to 
> make the calling script wait for the PHP script it is making use of 
> before it goes on and attempts to copy the created file.
> 
> I'm asking this because, to me, it doesn't seem to be, and I want to 
> figure out the "proper" way I can make the script wait for the 
> completion of the other script.
