while loop help

[solarisuser]

Hi All,

 

I'm trying to figure out if a while loop is what I really need to use.  My goal is to copy a dynamic amount of data from C:\ to D:\.

I have a routine to detect the used hard disk space on C:\ and the free disk space on D:\.  If D:\ does not have enough space for the copy, I delete a folder, then I want to run the code again to detect the used hard disk space on C:\ and the free disk space on D:\.  If I still need more space, I delete another folder, and run the code again, etc.

 

Right now I run the code to detect the hard disk size, and if I need to delete a folder, I have:

while($size_to_copy > $size_free)
{
// delete folder
// run code to update $size_to_copy and $size_free
}

 

However, running code inside the while loop to generate an updated $size_to_copy and $size_free do not seem to tell the while loop of the new values.

 

Any direction on my next steps would be great - thanks!

Changes inside the loop are checked again when the loop starts over.
