Sorting an array via user defined function - php

Question

I want a user defined function for sorting a multi dimension array:
<?php
$arr1 = array(
49,
8,
array(
'Muazam',
'Ali',
'Rana',
'Amina',
'Surya',
'Danish',
'Raina',
4,
3,
2,
1,
) ,
7,
6,
5,
4,
3,
2,
1,
0,
);
function abc($arr)
{
$len = count($arr) - 2;
foreach($arr as $key => $value)
{
for ($a = 0; $a <= $len; $a++)
{
if ($arr[$a] > $arr[$a + 1])
{
$temp4 = $arr[$a];
$arr[$a] = $arr[$a + 1];
$arr[$a + 1] = $temp4;
}
}
if (is_array($value))
{
abc($value, $a = $a + 1);
}
}
} //2nd foreach close
echo "<pre>";
print_r($arr);
echo "</pre>";
}

Answer 1

This is a basic usage of a recursive function:
$arr1 = array(49, 8, array(
'Muazam', 'Ali', 'Rana', 'Amina', 'Surya', 'Danish', 'Raina', 4, 3, 2, 1,
), 7, 6, 5, 4, 3, 2, 1, 0);
function recursiveSort(&$array)
{
foreach ($array as &$value) {
if (is_array($value)) {
recursiveSort($value);
}
}
return sort($array);
}
recursiveSort($arr1);
echo '<pre>';
print_r($arr1);
echo '</pre>';
The result would be:
Array
(
[0] => 0
[1] => 1
[2] => 2
[3] => 3
[4] => 4
[5] => 5
[6] => 6
[7] => 7
[8] => 8
[9] => 49
[10] => Array
(
[0] => Ali
[1] => Amina
[2] => Danish
[3] => Muazam
[4] => Raina
[5] => Rana
[6] => Surya
[7] => 1
[8] => 2
[9] => 3
[10] => 4
)
)

Answer 2

Here Is Answer.. Sorting a multi dimensional array without using built in function.
$arr1 = array(1,3,5,'2',array(99,55,array(111,444,array('a','r','p','e','t'),777),66,99),8,9,0,3,1);
function abc(&$arr)
{
$len=count($arr)-2;
foreach($arr as $key => &$value)
{
for ($a=0;$a<=$len;$a++){
if($arr[$a]>$arr[$a+1])
{
$temp4=$arr[$a];
$arr[$a]=$arr[$a+1];
$arr[$a+1]=$temp4;
}
}
if(is_array($value))
{
abc($value,$a=$a+1);
}
}//foreach close
//}//2nd foreach close
echo "<pre>";
return $arr;
echo "</pre>";
}//function close
print_r (abc($arr1));
