allows the sort criteria be passed as a separate array (It is possible to use sort order and flags. it prepares the arrays (needed by array_multisort) for you uses PHP's array_multisort function for sorting Purpose: Sort a 2-dimensional array on some key(s) I would like to see the next code snippet to be added to $arr2 = array_msort ( $arr1, array( 'name' => SORT_DESC, 'cat' => SORT_ASC )) įoreach ( $array as $k => $row ) $sorted = array_orderby ( $data, 'volume', SORT_DESC, 'edition', SORT_ASC ) Ī more inuitive way of sorting multidimensional arrays using array_msort() in just one line, you don't have to divide the original array into per-column-arrays:Īrray( 'id' => 2, 'name' => 'aa', 'cat' => 'dd' ),Īrray( 'id' => 3, 'name' => 'bb', 'cat' => 'cc' ),Īrray( 'id' => 4, 'name' => 'bb', 'cat' => 'dd' ) Pass the array, followed by the column names and sort flags Note: If two members compare as equal, they retain their original order. $data = array( 'volume' => 67, 'edition' => 7 ) usort Sort an array by values using a user-defined comparison function Description usort ( array &array, callable callback ): true Sorts array in place by values using a user-supplied comparison function to determine the order. You can update the locale yourself by using setlocale (). SORTLOCALESTRING compare the values as strings based on the current locale. SORTSTRING sort the values by comparing them as strings. SORTNUMERIC sort the values by comparing them numerically. $data = array( 'volume' => 86, 'edition' => 1 ) It can have six different values: SORTREGULAR sort the values without changing their types. The sorted array is now in the return value of the function instead of being passed by reference. This does what example 3 does, except it takes care of creating those intermediate arrays for you before passing control on to array_multisort().Ĭall_user_func_array ( 'array_multisort', $args ) I came up with an easy way to sort database-style results. In other words, the sort is lexicographical. Only elementsĬorresponding to equivalent elements in previous arrays are compared. More arrays, optionally followed by sort order and flags. Or omitted entirely, in which case SORT_REGULAR is assumed. This argument can be swapped with array1_sort_order SORT_NATURAL to sort strings case-insensitively SORT_NATURAL - compare items as strings.SORT_NUMERIC - compare items numerically.Sort options for the previous array argument: Or omitted entirely, in which case SORT_ASC is assumed. This argument can be swapped with array1_sort_flags SORT_ASC to sort ascendingly or SORT_DESC The order used to sort the previous array argument.
