Is there any way of knowing where the function was called?

If I have a huge project and I realize that somewhere in the code, a function is being called, but I don’t know where it is, is there any way to find out?

Example:

#index.php

// nada aqui nesse script

#config.php

$config['database'] = config('database');

#view.php

$base_url = config('base_name');

I’d like something like:

descubra_onde_a_funcao_foi_chamada('config');

And so return something like:

    array(
      0 => array( 'file' => 'config.php', 'line' => 10),
      1 => array('file'  => 'view.php', 'line' => 15)
   );

You can do something like this, in PHP, in the same way I demonstrated in the example function?

Location where the function was called is different from how many times it was called. Help me out, here!

got it, would you find it too broad to gather this question in the other ? a function that checks where it was called and counts how many times it was executed ?

Yes, they are different subjects. Unless the function does both, without complicating the midfield.

@Gabrielrodrigues, I usually group questions, but sometimes it is impossible (I don’t like giant answers)

The function debug_print_backtrace() displays the call stack to the point where the function is executed.

Although the documentation does not show, this function receives an optional parameter with the constant value DEBUG_BACKTRACE_IGNORE_ARGS, which hides the parameters of the called functions.

<?php
debug_print_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS);

Example of displayed content:

#0  c() called at [/tmp/include.php:10]
#1  b() called at [/tmp/include.php:6]
#2  a() called at [/tmp/include.php:17]
#3  include(/tmp/include.php) called at [/tmp/test.php:3]
