Tracking Memory Usage in PHP
I’m trying to track the memory usage of a script that processes URLs. The basic idea is to check that there’s a reasonable buffer before adding another URL to a cURL multi handler. I’m using a ‘rolling cURL’ concept that processes a URLs data as the multi handler is running. This means I can keep N connections active by adding a new URL from a pool each time an existing URL processes and is removed.

If the real_usage argument is set to true the PHP DOCS say it will get the real size of memory allocated from system. If it’s false it will get the memory reported by emalloc()
Memory optimization in PHP array
I’m working with a large array which is a height map, 1024×1024 and of course, i’m stuck with the memory limit. In my test machine i can increase the mem limit to 1gb if i want, but in my tiny VPS with only 256 ram, it’s not an option.
