Bug description:Extend array_walk_recursive to provide context information to
the callback func
Description:
------------
It is easy to extend the array_walk_recursive function to be more useful in
non-
trivial situations which require information about depth & path in the
array
structure the cursor is in, by adding an optional 4th parameter. This
would
eliminate the need for MANY user-written depth first search traversal
recursive
functions. Which consequently makes PHP a more attractive language for
people
who
fear recursion, but need a tree walk function which provides contextual
information to the callback.
bool array_walk_recursive ( array &$input , callback $funcname [, mixed
$userdata
] [, array $state] )
where $state is a data dictionary having any number of context relevant
data
e.g.
the depth of recursion (int), and the keys traversed to arrive at this node
(a
1-
dimensional list array of string).
This enhancement is low risk: it would not break backward-compatibility.
This enhancement is high reward: it would make Xpath-like operations more
approachable to the average developer.
This enhancement would simplify user code: which tends to increase security
for
websites.
Test script:
---------------
var $state = Array(
$depth => 0
,$path => Array()
);
Expected result:
----------------
N/A
Actual result:
--------------
N/A
