How to get PHP script use more CPU for simple looping task? -


i have simple script tries find md5 collisions via brute force.

// pseudo: while (runtime < 25 seconds) {   random_hash1 = random_hash();   random_hash2 = random_hash();    if (random_hash1 == random_hash2) {     notify_user();   } }

it's working fine around 8 million iterations during 25 second window. during run cpu usage stays @ 0-1%. i'm running on 4 cores @ 3.8ghz. how can utilize cpu more php?

if did java or c++ instantly eat whole cpu while (1) loop , iteration count boost lot php.

ps. know finding collision impropable fun.

how can utilize cpu more php?

you try multi-threading approach using pthreads

from documentation:

pthreads object orientated api allows user-land multi-threading in php. includes tools need create multi-threaded applications targeted @ web or console. php applications can create, read, write, execute , synchronize threads, workers , stackables.
