analyse PHP code function calling

analyse PHP code function calling

I'm writing PHP codes but unlike Visual Studio, you cannot ask PHP to tell
you in what locations is a function called.
suppose I have code in CodeIgniter:
controller.php
class Ccc: CI_Controller
{
...
function myf1()
{
$this->load->model('mmm');
$this->mmm->funcB();
}
}
in model.php
class Mmm : CI_Model
{
...
function funcB()
{
.....
}
}
I need a report which tells me Mmm.funcB is called from Ccc.myf1 and from
which other locations.
