I have one array as
$tmpArr = array('A', 'B', 'C');
I want to process this array and want new array as
$tmpArr[A][B][C] = C
I.e last element becomes the value of final array.
Can anyone suggest the solution? Please help. Thanks in advance

id on't think this makes any sense, too, but if you wan't help, please provide a little more information - what schould happen is the input inrray has more/less than 3 elements? what have you tried till now? why do yau have to do this transformation and can't do it like you need when you're creating the array?oezi– oezi2010-09-27 13:14:50 +00:00Commented Sep 27, 2010 at 13:14

Iterate the array of keys and use a reference for the end of the chain:
$arr = array();
$ref = &$arr;
foreach ($tmpArr as $key) {
$ref[$key] = array();
$ref = &$ref[$key];
}
$ref = $key;
$tmpArr = $arr;

You beat me to it. I had almost exactly the same thing (the only difference is the variable names)... +1
$tmpArr = array('A', 'B', 'C');
$array = array();
foreach (array_reverse($tmpArr) as $arr)
$array = array($arr => $array);
Output:
Array
(
[A] => Array
(
[B] => Array
(
[C] => Array
(
)
)
)
)
