PHP - Out of memory - where does the memory go?

Question

PHP

There is a script that throws Out of Memory during operation - it is clear that somewhere something is not released.
How can you determine where? How can I see which variables take up how much memory space at the time of the error?
Xdebug help?

Answer 1

I recommend memtrack . Allows you to display line by line who ate what. If it's a cron, it's better to call the gc_collect_cycles collector instead . And check that the garbage collector is enabled at all.

Answer 2

memory_get_usage but it will only show the memory usage.
unset() in the right place can do a lot.

Answer 3

XDebug will help

Answer 4

Xdebug + KCachegrind + easy XDebug (firefox).

Answer 5

XDebug will help and a lot of luck.
First of all, I would pay attention to recursive functions and resource-intensive queries to the database.

Answer 6

where does the memory go
to which cities
and where can we find a remedy...
