Free Array

[Anon]

Dear all,

I often allocate a large size of two-dimension array (ex: 1000*1000) with storing short strings as elements. I found that the memory is blocked in our system (SunOS 5.8) even the program has already ended. The memory of "swap in use" is never free until I restart my web server.

How could I destroy or free my large-size array after executing my programs?

Thanks for your help!

Uhm.. allocate memory in PHP? how? any why??

I just insert elements into array and use them. Actually I don't know how PHP implements memory allocation. But I am sure that the value of "swap in use" increases at each time I run my program.

Swap memory on SUN machines is a file stored on disk. I can magine that the OS tries to keep the changes to the size of that file to a minimum for performance reasons.

PHP frees all it's allocated memory when the script exits.

It might be usefull to check for a newer version of PHP/Apache in case there really is a memory-leak under SunOS.
