i tried the uksort but it only sorts the first array..
uksort($m_array,'sort_function');
function sort_function($a,$b){
if($a>$b){
return true;
}else if($a<$b){
return false;
}else{
return 0;
}
}

Finally Found The Solution:
This is The Unsorted Array
Array
(
[10] => Array
(
[67] => Array
(
[43] => Array
(
[23] => Array
(
[5] => 123
[12] => 321
[8] => 543
[15] => 351
[1] => 323
[13] => 209
)
[65] => 123
[45] => 321
[87] => 543
[56] => 351
[1] => 323
[13] => 209
)
[54] => 123
[41] => 321
[4] => 543
[55] => 351
[1] => 323
[13] => 209
)
[15] => 123
[26] => 321
[37] => 543
[48] => 351
[68] => 323
[13] => 209
)
[5] => Array
(
[43] => Array
(
[23] => Array
(
[5] => 123
[12] => 321
[8] => 543
[15] => 351
[1] => 323
[13] => 209
)
[65] => 123
[45] => 321
[87] => 543
[56] => 351
[1] => 323
[13] => 209
)
[54] => 123
[41] => 321
[4] => 543
[55] => 351
[1] => 323
[13] => 209
)
[15] => Array
(
[23] => Array
(
[5] => 123
[12] => 321
[8] => 543
[15] => 351
[1] => 323
[13] => 209
)
[65] => 123
[45] => 321
[87] => 543
[56] => 351
[1] => 323
[13] => 209
)
[25] => Array
(
[5] => 123
[12] => 321
[8] => 543
[15] => 351
[1] => 323
[13] => 209
)
)
Here Is My Code:
function recursive_sort(&$m_array) {
fs($m_array);
if(is_array($m_array)){
foreach($m_array as $k=> &$v){
if (isset($v)) {
recursive_sort($v);
}
}
}
}
function sortByOrder($a, $b) {
if($a>$b){
return true;
}else if($a<$b){
return false;
}else{
return 0;
}
}
function fs(&$m_array){
if(is_array($m_array)){
uksort($m_array, 'sortByOrder');
}
}
recursive_sort($m_array);
print_r($m_array);
And Here Is The Output:
Array
(
[5] => Array
(
[1] => 323
[4] => 543
[13] => 209
[41] => 321

)
[45] => 321
[56] => 351

[87] => 543
)
[54] => 123
[55] => 351
)

This is a recursive ksort solution:
$m_array = [
2 => [
22 => [
229 => 'i',
221 => 'h'
],
21 => 'g'
],
1 => [
12 => [
122 => 'f',
121 => [
1212 => 'e',
1211 => 'd'
]
],
11 => [
111 => [
1112 => 'b',
1119 => 'c',
1111 => 'a'
]
],
],
];
function ksort_recursive(&$array) {
if (is_array($array)) {
array_walk($array, "ksort_recursive");
ksort($array);
}
}
ksort_recursive($m_array);
print_r($m_array);
Output:
Array
(
[1] => Array
(
[11] => Array
(
[111] => Array
(
[1111] => a
[1112] => b
[1119] => c
)
)
[12] => Array
(
[121] => Array
(
[1211] => d
[1212] => e
)
[122] => f
)
)
[2] => Array
(
[21] => g
[22] => Array
(
[221] => h
[229] => i
)
)
)
