How do I disable garbage collection for a long running php cli script? I am handling unsetting of variables in the script.

Unsetting variables does not free memory! It just removes the reference from the variable to the corresponding value. Once any value have a ref-count of 0 the GC collects the value and frees its allocated memory. If it would be possible to completely disable the GC you would break your interpreter (in best case): You will have many many unreferenced data in your memory, that will never get cleaned. Thats called “memory leak”.
