Bug description: Enhance debug_backtrace to supply the name of parameters.
Description:
------------
Currently, debug_backtrace() supplies details of parameters to the
function/method calls in the current call stack. This is extremely useful
for debugging.
I feel that this could be enhanced by adding the name of the parameters
passed to a function/method.
Currently I have to read the file associated with the function and then
regexp the line to extract the parameters. This is getting more and more
complicated trying to support different users coding practices.
I've supplied an contrived example with the expected output for the new
functionality.
I initially thought that the keys of the 'args' array could be the
parameters, but this would be a BC as currently they are numeric, so a new
array of 'params' (Hmmm - not a great name - would need a better one),
could hold the parameter text. If the parameter is a function call, then
the param value would be the function call with its parameters.
The main purpose is that you can show the actual parameter names the code
is using in addition to the the values.
Reproduce code:
---------------
<?php
function func($m_Param1, $m_Param2)
{
var_export(debug_backtrace());
return True;
}
$s_Foo = 'Foo';
$s_Bar = 'Bar';
func($s_Foo, $s_Bar, func($s_Foo, $s_Bar));
?>
Expected result:
----------------
array (
0 =>
array (
'file' => 'C:\\va.php',
'line' => 10,
'function' => 'func',
'args' =>
array (
0 => 'Foo',
1 => 'Bar',
),
'params' =>
array (
0 => '$s_Foo',
1 => '$s_Bar',
),
),
)array (
0 =>
array (
'file' => 'C:\\va.php',
'line' => 10,
'function' => 'func',
'args' =>
array (
0 => 'Foo',
1 => 'Bar',
2 => true,
),
'params' =>
array (
0 => '$s_Foo',
1 => '$s_Bar',
2 => 'func($s_Foo, $s_Bar)',
),
),
)
Actual result:
--------------
array (
0 =>
array (
'file' => 'C:\\va.php',
'line' => 10,
'function' => 'func',
'args' =>
array (
0 => 'Foo',
1 => 'Bar',
),
),
)array (
0 =>
array (
'file' => 'C:\\va.php',
'line' => 10,
'function' => 'func',
'args' =>
array (
0 => 'Foo',
1 => 'Bar',
2 => true,
),
),
)
