Look at a multidimensional array sort

<?php
function Sortdata ($data, $col, $order) {
if (count ($data)) $temp _array[key ($data)] = Array_shift ($data);

foreach ($data as $key => $val) {
$offset = 0;
$found = false;
foreach ($temp _array as $tmp _key => $tmp _val) {
if (! $found and Strtolower ($val [$col]) >

Strtolower ($tmp _val[$col])) {
$temp _array = Array_merge ((array)

Array_slice ($temp _array,0, $offset),
Array ($key => $val),
Array_slice ($temp _array, $offset)
);
$found = true;
}
$offset + +;
}
if (! $found) {
$temp _array = Array_merge ($temp _array, array

($key => $val));
}
}
if (Strtolower ($order) = = "ASC") {
$array = Array_reverse ($temp _array);
} else {
$array = $temp _array;
}
return $array;
}

Main function

$data =array (
Array
' Name ' => ' Alice ',
' Key ' => ' 2fc4ab3d639e5400efdfc73bc27e83f1 ',
' Age ' =>20
),
Array
' Name ' => ' Claudia ',
' Key ' => ' 831c2b79c1f19af39c7e3321e11e5f5e ',
' Age ' =>18
),
Array
' Name ' => ' Beatrice ',
' Key ' => ' 6f8512a2066b8f35a27a495ce1228c76 ',
' Age ' =>100
),
Array
' Name ' => ' Denise ',
' Age ' =>25,
' Key ' => ' Ef6de3b178bf9f69a9fef72e4ee7bbe9 '

$arr 1 = sortdata ($data, "name", "ASC");
echo "<pre>";
Var_dump ($arr 1);
