I am using PHP version 5.1.2. on my dev machine. The same problem with
PHP 5.2.1 on webserver.
I am generating mails based on a HTML Template. After reading the
template with fread() memory_get_usage() says ~386 MB in use...
Then the placeholders in the read template are replaced by customized
values within a loop. The size of the used memory grows permanently in
each loop by approx 30 MB (100 newsletters are generated per loop).
any ideas what i am doing wrong and where i [ab]use php? ^^

Hello all,
is there a way to free memory allocated by variables in PHP?? This is a
very important issue concerning long running scripts...
this is a recurrent problem - not much can be done about it AFAIK ... I'd
be very glad to be proved wrong.
I have a script that generates > 5000 Newsletters and when the script
finishes it uses 1.8 GB (!!) of RAM. Although I am using unset() to
clean up variables (tried with $var = null too).
okay this does suggest your doing something else very wrong - I personally
have code that regularly generates upto 20,000 individualised newsletters without
going anywhere near this ammount of memory - granted I've hit my memory limit
a couple of times and had to jack it up to 128Megs (in practice the script grab just over
64Megs when it's doing it's worst).
what version of php are you [ab]using?
I've read sth about php not giving the allocated memory back to the OS
until a script finishes, is that right?? Is it possible to free the
memory "by hand"?
Any suggestion is appreciated!
thx in advance
