Couple of questions come to mind... 1. How big is this template that you're loading? Not sure why almost any HTML file would take up 300+ meg of memory when loaded into a variable. Are you loading images and other content in as well or just the HTML file?
2. Replacing the placeholders with actual data increases memory that much? Damn.. maybe I'm just ignorant of how PHP maintains things in memory, but that seems kind of nuts too 3. Do you have to store each newsletter in memory at each loop or can you send them out then move to the next one without storing them in an array or whatever you're doing? 4. Please tell us these 'newsletters' don't contain information on "male enhancement products" or "govt seized puppies"..hah -TG = = = Original message = = = 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? ^^ Jochem Maas schrieb: > Arthur Erd~s wrote: >> Hello all, >> >> is there a way to free memory allocated by variables in PHP??
