How to trace code execution in PHP?

I would like to see a log of THE WHOLE code execution of PHP script(s). Something like this: http://en.wikibooks.org/wiki/Ruby_Programming/Standard_Library/Tracer (for lack of better example; no flame please).

Is there some way how to obtain the log in PHP?

Note: I know I can use a debugger but that's not the same.

This is what I need to traces all the lines when running php or Laravel framework in windows sub-system for linux (WSL).

Install xdebug in the system then edit /etc/php/7.4/mods-available/xdebug.ini with the following details 

zend_extension=xdebug.so
xdebug.default_enable=1
xdebug.remote_enable=1
xdebug.remote_connect_back=1
xdebug.remote_port = 9001
xdebug.scream=0
xdebug.cli_color=1
xdebug.show_local_vars=1
xdebug.remote_autostart=1

; this part here, above is used for line by line debug in vscode
xdebug.auto_trace=1
xdebug.trace_output_dir = /mnt/c/projects/www/phptraces
xdebug.trace_output_name=trace.%u
xdebug.collect_params=4
xdebug.trace_format = 1

This one here 

xdebug.trace_output_dir = /mnt/c/projects/www/phptraces

is the path where to store logs

For laravel framework it generate very large file most likely 4GB in size. So I used 

split -l 1000 trace.1576842503_368392.xt pieces/traces

to split it into smaller parts containing 1000 lines each and store it into pieces directory.

Then you can use editor find in files what your looking for

Have a look at Kint.

debug backtrace screenshot

It's var_dump() and debug_backtrace() on steroids. Easy to use, but powerful and customizable. An essential addition to your development toolbox.

it also has platform specific extensions here

In any function you can see the whole backtrace by using debug_backtrace(...)

Or you can use Xdebug profiler to profile your PHP scripts.

You can use a PHP extension called : XHProf, developed by Facebook.

It is capable of reporting function-level call counts and inclusive and exclusive wall time, CPU time and memory usage.

Xdebug is definitely what you want, but with something like callgrind from the valgrind suite as well.

Zend blog post here should give you some pointers: http://devzone.zend.com/1139/profiling-php-applications-with-xdebug/
