Hello,
I have a rather complex set of PHP scripts that make use of some objects
and *sometime* receive a message from PHP saying it has exceeded the 8Mb
memory limit.
Being the code deeply structured, I believe there should be no reason
for having allocated such a memory quantity, so am posing a couple of
questions:
1 - is there a way to check for where *actually* is the memory
allocated? Ideally I would like to know which
variables holds all the memory.
2 - are there any techniques to lower the memory requirement?
The impression I have (and it is only an impression, so I need (1)
above) is there is some kind of memory leakage or objects/variables that
aren't correctly deallocated. I make heavy use of string concatenation
operator, building rather big strings in memory. Does this cause some kind
of memory fragmentation problem?
Is passing return values by reference actually more efficient (it avoids
copying the result) or is it optimized in some way?
Thanks for your help.
