PHP array_multisort() Function

Hello folks! welcome back to a new section of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP array_multisort() Function.

The built-in PHP array_multisort() function is used for sorting several arrays at once, or a multi-dimensional array by one or more dimensions.


Following below is the syntax to use this function -

array_multisort(array1,sorting order,sorting type,array2...);

Parameter Details

Sr.NoParameter & Description


It specifies an array


Sort order(Optional)

It specifies the sorting order. Possible values −

  • SORT_ASC Default. Sort in ascending order (A-Z)
  • SORT_DESC sort in descending order (Z-A)

Sorting type(Optional)

It specifies the type to use, when comparing elements. Possible values −

  • SORT_REGULAR Default. Compare elements normally
  • SORT_NUMERIC Compare elements as numeric values
  • SORT_STRING Compare elements as string values


It specifies an array

Return Value

This function returns TRUE on success or False on failure.


Try out the below example -

   $input1 = array("10", 100, 100, "a");
   $input2 = array(1, 3, "2", 1);
   array_multisort($input1, $input2);


When the above code is executed, it will produce the following result -

Array ( [0] => 10 [1] => a [2] => 100 [3] => 100 ) Array ( [0] => 1 [1] => 1 [2] => 2 [3] => 3 )
