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? ^^ > Arthur Erdös wrote: > > Hello all, > > > > is there a way to free memory allocated by variables in PHP??
