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()."<br>"; which is a start. — Funk Forty Niner

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

Maybe there's something in the manual for it 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

This Q&A stackoverflow.com/q/2192657 and 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

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.
