Sorry to post this again but it's a little urgent.
The preg_replace in my script allocates a little memory every time it is called and
doesn't free it again untill the script ends.
I don't know if it is normal behaviour for preg_replace or if it is my reg. exp.
that causes this.
The problem is that I call preg_replace a little more than 30000 times and that
causes quite a lot of memory to be allocated.
Doesn't anybody know if this is a problem in preg_replace or is there a better
maillist/forum for this kind of questions?
Any answer will be appreciated :)
