Here is a function to sort an array by the key of his sub-array.
<?php
function sksort(&$array, $subkey="id", $sort_ascending=false) {
if (count($array))
$temp_array[key($array)] = array_shift($array);
foreach($array as $key => $val){
$offset = 0;
$found = false;
foreach($temp_array as $tmp_key => $tmp_val)
{
if(!$found and strtolower($val[$subkey]) > strtolower($tmp_val[$subkey]))
{
$temp_array = array_merge( (array)array_slice($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 => $val));
}
if ($sort_ascending) $array = array_reverse($temp_array);
else $array = $temp_array;
}
?>
Example
<?php
$info = array("peter" => array("age" => 21,
"gender" => "male"
),
"john" => array("age" => 19,
"gender" => "male"
),
"mary" => array("age" => 20,
"gender" => "female"
)
);
sksort($info, "age");
var_dump($info);
sksort($info, "age", true);
var_dump($ifno);
?>
This will be the output of the example:
/*DESCENDING SORT*/
array(3) {
["peter"]=>
array(2) {
["age"]=>
int(21)
["gender"]=>
string(4) "male"
}
["mary"]=>
array(2) {
["age"]=>
int(20)
["gender"]=>
string(6) "female"
}
["john"]=>
array(2) {
["age"]=>
int(19)
["gender"]=>
string(4) "male"
}
}
/*ASCENDING SORT*/
array(3) {
["john"]=>
array(2) {
["age"]=>
int(19)
["gender"]=>
string(4) "male"
}
["mary"]=>
array(2) {
["age"]=>
int(20)
["gender"]=>
string(6) "female"
}
["peter"]=>
array(2) {
["age"]=>
int(21)
["gender"]=>
string(4) "male"
}
}
