$counter2
= function()

0
;
return ++
$d
;
};
function
dumpReflectionFunction
(

{
// Print out basic information
printf
(
"\n\n===> The %s function '%s'\n"
.
" declared in %s\n"
.
" lines %d to %d\n"
,
$func
->

// Print static variables if existant
if (

}
// Create an instance of the ReflectionFunction class

The above example will output something similar to:
===> The user-defined function 'counter1'
declared in Z:\reflectcounter.php
lines 7 to 11
---> Documentation:
'/**
* A simple counter
*
* @return int
*/'
---> Static variables: array (
'c' => 0,
)
===> The user-defined function '{closure}'
declared in Z:\reflectcounter.php
lines 18 to 23
---> Documentation:
'/**
* Another simple counter
*
* @return int
*/'
---> Static variables: array (
'd' => 0,
