How to debug memory leaks in php?

Question

PHP

Hello. There is a demon that spins in an eternal cycle (the doctrine is used there, maybe it doesn’t clean up something). Tell me, can there be any tools for debugging memory leaks? Or how do you find leaks?

Answer 1

Isn't it easier to raise a normal demon? https://daemon.io

Answer 3

Do you clean up the Identity Map ?
And surely some XDebug is not included?
In general, you need a profiler. Above one has already been suggested. There are also xhprof and blackfire.io .

Answer 4

Logging at the first stage is necessary with fixing the size of the used memory. At the second stage, when at least some localization of the problem area will be, really use the profiler.
