multidimensional array sort based on database column value compare - php

Question

I have following multidimensional array
Array
(
[1] => 22
[2] => 12
[3] => Array
(
[0] => 4
[1] => 21
)
[5] => Array
(
[0] => 9
[1] => 3
)
[7] => 7
[8] => 6
[9] => 1
[10] => 2
[11] => 10
[12] => 0
[13] => 23
[14] => 18
[15] => 16
[16] => 19
[17] => 15
[18] => 5
[19] => 8
[20] => 11
[21] => 13
[22] => 17
[23] => 14
[24] => 20
)
I want to sort morethan one value below array from main array.
Array
(
[3] => Array
(
[0] => 4
[1] => 21
)
[5] => Array
(
[0] => 9
[1] => 3
)
)
Each key value compare with database column and sort an array. If not found value then array keep as it is.
For example:
The below key value is 21 have in database column then am expected results as,
[3] => Array
(
[0] => 21
[1] => 4
)
look as next array, the next array key value not found in the database then expected results as it is,
[5] => Array
(
[0] => 9
[1] => 3
)
The final output look for,
Array
(
[1] => 22
[2] => 12
[3] => Array
(
[0] => 21
[1] => 4
)
[5] => Array
(
[0] => 9
[1] => 3
)
[7] => 7
[8] => 6
[9] => 1
[10] => 2
[11] => 10
[12] => 0
[13] => 23
[14] => 18
[15] => 16
[16] => 19
[17] => 15
[18] => 5
[19] => 8
[20] => 11
[21] => 13
[22] => 17
[23] => 14
[24] => 20
)
Could you please help me

Answer 1

Check this.
$dump_array=Array('1' => 2,'2' => 12,'3' => Array
('0' => 8,'1' => 21 ),
'5' => Array ('0' => 9,'1' => 3),
'7' => 7,
'8' => 64,
'9' => 15,
'10' => 22,
);
echo "<pre> Soure :"; print_r($dump_array);echo "</pre>";
sort($dump_array);
$result_array=array();
$array_unlist=array();
foreach($dump_array as $key=>$value){
if(is_array($value)){
sort($value);
array_push($array_unlist,$value);
}
else {array_push($result_array,$value);}
}
foreach($result_array as $index=>$val){
foreach($array_unlist as $key=>$digit){
if($val<$digit[0])
{
$res=$index.".5";
$result_array[$res]=$digit;
}
}
}
ksort($result_array);
echo "<pre> Result :"; print_r(array_values($result_array));echo "</pre>";
output:
Soure :Array
(
[1] => 2
[2] => 12
[3] => Array
(
[0] => 8
[1] => 21
)
[5] => Array
(
[0] => 9
[1] => 3
)
[7] => 7
[8] => 64
[9] => 15
[10] => 22
)
Result :Array
(
[0] => 2
[1] => Array
(
[0] => 3
[1] => 9
)
[2] => 7
[3] => Array
(
[0] => 8
[1] => 21
)
[4] => 12
[5] => 15
[6] => 22
[7] => 64
)

try this
foreach($array as $k => $v){
if(is_array($v)){
rsort($array[$k]);
}
}
print_r($array);
