Optimize PHP scripts

Question

Do you know if there's a way to log how much memory is used in PHP scripts?.

I would like a log that tells me which objects are using more memory, which functions I need to improve, etc.

It would be something like memory_get_usage but for each line of code.

`echo "MEMORY USAGE: ". memory_get_usage()."
";` which is a start. — Funk Forty Niner, May 24 '14 at 13:25
I mean something like that but I won't copy that for each line of code... I was asking if there's a way to do that automatically. — Raul Leaño Martinet, May 24 '14 at 13:27
Maybe there's something in the manual for it http://www.php.net/manual/en/function.memory-get-usage.php and Google the function. You may very well find something. But that's the function you need. — Funk Forty Niner, May 24 '14 at 13:28
Already checked... there's nothing like the thing I'm looking for — Raul Leaño Martinet, May 24 '14 at 13:33
This Q&A http://stackoverflow.com/q/2192657/ and http://blog.gigavoice.com/php-data-structures/ after Googling `"memory_get_usage() for individual items php"` where you'll find more, I am sure. — Funk Forty Niner, May 24 '14 at 13:35
If you're looking to profile your code, look at using xdebug or xhprof — Mark Baker, May 24 '14 at 14:39

Xdebug's execution trace might be closest to what you're looking for. It traces every include, function call and method call to a human-readable file that can optionally (with xdebug.show_mem_delta setting on) show the difference in memory usage between calls.
