2 dimensional array to sort using PHP - php

Question

MY CODE IS :
$arr = array(
array(
"title" => "Volvo"
),
array(
"title" => "BMW"
),
array(
"title" => "Saab"
),
array(
"title" => "Aam"
)
);
$a = aasort($arr,"title");
echo "<pre>",print_r($a),"</pre>";
function aasort (&$array, $key) {
$sorter=array();
$ret=array();
reset($array);
foreach ($array as $ii => $va) {
$sorter[$ii]=$va[$key];
}
natcasesort($sorter);
foreach ($sorter as $ii => $va) {
$ret[$ii]=$array[$ii];
}
$array=$ret;
return $array;
}
and the output is :
Array
(
[3] => Array
(
[title] => Aam
)
[1] => Array
(
[title] => BMW
)
[2] => Array
(
[title] => Saab
)
[0] => Array
(
[title] => Volvo
)
)

But i want output like :
Array
(
[0] => Array
(
[title] => Aam
)
[1] => Array
(
[title] => BMW
)
[2] => Array
(
[title] => Saab
)
[3] => Array
(
[title] => Volvo
)
)

How to do it ?

Answer 1

You can reindex an array with array_values():
$array = array_values($ret);

Answer 2

Try this it will help you :
$result = array();
$result = sortArray($array,'key');
Here, $array is unsorted array. So you can sort it by call sortArray function.
<?php
function sortArray($arrData, $p_sort_field, $p_sort_type = false )
{
if(!empty($arrData))
{
foreach($arrData as $data)
{
$newData [] = $data;
}
for($i=0; $i<count($newData); $i++)
{
$ar_sort_field[$i]=$newData[$i][$p_sort_field];
}
array_multisort($ar_sort_field, ($p_sort_type ? SORT_DESC : SORT_ASC), $newData);
return $newData;
}
}
?>

Answer 3

Try this..
$arr = array(
array(
"title" => "Volvo"
),
array(
"title" => "BMW"
),
array(
"title" => "Saab"
),
array(
"title" => "Aam"
)
);
$arr = msort($arr, array('title'));
print_r($arr);
function msort($array, $key, $sort_flags = SORT_REGULAR) {
if (is_array($array) && count($array) > 0) {
if (!empty($key)) {
$mapping = array();
foreach ($array as $k => $v) {
$sort_key = '';
if (!is_array($key)) {
$sort_key = $v[$key];
} else {
// #TODO This should be fixed, now it will be sorted as string
foreach ($key as $key_key) {
$sort_key .= $v[$key_key];
}
$sort_flags = SORT_STRING;
}
$mapping[$k] = $sort_key;
}
asort($mapping, $sort_flags);
$sorted = array();
foreach ($mapping as $k => $v) {
$sorted[] = $array[$k];
}
return $sorted;
}
}
return $array;
}
Result
Array ( [0] => Array ( [title] => Aam ) [1] => Array ( [title] => BMW )
[2] => Array ( [title] => Saab ) [3] => Array ( [title] => Volvo ) )`
