Hi, That's what I was thinking too, Ron. Internally, the functions zend_memory_[peak_]usage() would also get a flag parameter, or separate functions...
There's also the small issue of which size to set Apache's mod_php_mem_usage to. Dmitry, et al., I don't know the details of how the Memory Manager works, but I assume multiple memory blocks can have free space (if something didn't fit, and now block(s) were allocated). So if memory_get_usage() operates like before (reflecting small changes) and it's being used to make sure to stay under memory_limit, for example, memory_limit could be exhasted sooner than expected since the REAL allocated size is compared with heap->limit. Could/should the limit be compared to size that's measured the old way, or might that allow too much to "escape?" Hope you don't mind my random thoughts. :-) Matt ----- Original Message ----- From: "Ron Korving" Sent: Tuesday, July 25, 2006 > Perhaps it'd be a nice alternative to have an optional parameter?
