ARRAY_MULTISORT(3) 1 ARRAY_MULTISORT(3)
array_multisort - Sort multiple or multi-dimensional arrays
SYNOPSIS
bool array_multisort (array &$array1, [mixed $array1_sort_order = SORT_ASC], [mixed $array1_sort_flags = SORT_REGULAR], [mixed $...])
DESCRIPTION
array_multisort(3) can be used to sort several arrays at once, or a multi-dimensional array by one or more dimensions.
Associative ( string) keys will be maintained, but numeric keys will be re-indexed.
PARAMETERS
o $array1
- An array being sorted.
o $array1_sort_order
- The order used to sort the previous array argument. Either SORT_ASC to sort ascendingly or SORT_DESC to sort descendingly. This
argument can be swapped with $array1_sort_flags or omitted entirely, in which case SORT_ASC is assumed.
o $array1_sort_flags
- Sort options for the previous array argument: Sorting type flags:
o SORT_REGULAR - compare items normally (don't change types)
o SORT_NUMERIC - compare items numerically
o SORT_STRING - compare items as strings
o SORT_LOCALE_STRING - compare items as strings, based on the current locale. It uses the locale, which can be changed using
setlocale(3)
o SORT_NATURAL - compare items as strings using "natural ordering" like natsort(3)
o SORT_FLAG_CASE - can be combined (bitwise OR) with SORT_STRING or SORT_NATURAL to sort strings case-insensitively
This argument can be swapped with $array1_sort_order or omitted entirely, in which case SORT_REGULAR is assumed.
o $...
- More arrays, optionally followed by sort order and flags. Only elements corresponding to equivalent elements in previous arrays
are compared. In other words, the sort is lexicographical.
RETURN VALUES
Returns TRUE on success or FALSE on failure.

EXAMPLES
Example #1
Sorting multiple arrays
<?php
$ar1 = array(10, 100, 100, 0);
$ar2 = array(1, 3, 2, 4);
array_multisort($ar1, $ar2);
var_dump($ar1);
var_dump($ar2);
?>
In this example, after sorting, the first array will contain 0, 10, 100, 100. The second array will contain 4, 1, 2, 3. The entries
in the second array corresponding to the identical entries in the first array (100 and 100) were sorted as well.
array(4) {
[0]=> int(0)
[1]=> int(10)
[2]=> int(100)
[3]=> int(100)
}
array(4) {
[0]=> int(4)
[1]=> int(1)
[2]=> int(2)
[3]=> int(3)
}
Example #2
Sorting multi-dimensional array
<?php
$ar = array(
array("10", 11, 100, 100, "a"),
array( 1, 2, "2", 3, 1)
);
array_multisort($ar[0], SORT_ASC, SORT_STRING,
$ar[1], SORT_NUMERIC, SORT_DESC);
var_dump($ar);
?>
In this example, after sorting, the first array will transform to "10", 100, 100, 11, "a" (it was sorted as strings in ascending
order). The second will contain 1, 3, "2", 2, 1 (sorted as numbers, in descending order).
array(2) {
[0]=> array(5) {
[0]=> string(2) "10"
[1]=> int(100)
[2]=> int(100)
[3]=> int(11)
[4]=> string(1) "a"
}
[1]=> array(5) {
[0]=> int(1)
[1]=> int(3)
[2]=> string(1) "2"
[3]=> int(2)
[4]=> int(1)
}
}
Example #3
Sorting database results
For this example, each element in the $data array represents one row in a table. This type of dataset is typical of database
records.
Example data:
volume | edition
-------+--------
67 | 2
86 | 1
85 | 6
98 | 2
86 | 6
67 | 7
The data as an array, called $data. This would usually, for example, be obtained by looping with mysql_fetch_assoc(3).
<?php
$data[] = array('volume' => 67, 'edition' => 2);
$data[] = array('volume' => 86, 'edition' => 1);
$data[] = array('volume' => 85, 'edition' => 6);
$data[] = array('volume' => 98, 'edition' => 2);
$data[] = array('volume' => 86, 'edition' => 6);
$data[] = array('volume' => 67, 'edition' => 7);
?>
In this example, we will order by $volume descending, $edition ascending.
We have an array of rows, but array_multisort(3) requires an array of columns, so we use the below code to obtain the columns, then
perform the sorting.
<?php
// Obtain a list of columns
foreach ($data as $key => $row) {
$volume[$key] = $row['volume'];
$edition[$key] = $row['edition'];
}
// Sort the data with volume descending, edition ascending
// Add $data as the last parameter, to sort by the common key
array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $data);
?>
The dataset is now sorted, and will look like this:
volume | edition
-------+--------
98 | 2
86 | 1
86 | 6
85 | 6
67 | 2
67 | 7
Example #4
Case insensitive sorting
Both SORT_STRING and SORT_REGULAR are case sensitive, strings starting with a capital letter will come before strings starting with
a lowercase letter.
To perform a case insensitive search, force the sorting order to be determined by a lowercase copy of the original array.
<?php
$array = array('Alpha', 'atomic', 'Beta', 'bank');
$array_lowercase = array_map('strtolower', $array);
array_multisort($array_lowercase, SORT_ASC, SORT_STRING, $array);
print_r($array);
?>
The above example will output:
Array
(
[0] => Alpha
[1] => atomic
[2] => bank
[3] => Beta
)
