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 PHP Sort Array How to sort an array by Key or Value in PHP sort()- Sort Array in Ascending Order rsort()- Sort Array in Descending Order asort()- Sort. 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 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. 'email' => = array_column ( $records, 'first_name' ) Īrray_multisort ( $key_values, SORT_ASC, $records ) Īfter sorting, the $records array is returned in the following order.Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ? This help j Next menu item k Previous menu item g p Previous man page g n Next man page G Scroll to bottom g g Scroll to top g h Goto homepage g s Goto search In this example code snippet, the first_name key is specified to sort the $records array in ascending order. Use PHP array_multisort() function to sort an array by key value.Use PHP array_column() function to get values from a specifc key column in array.The following code helps to sort multi-dimensional arrays by key in PHP. In this example code snippet, we will show you how to sort the order of multi-dimensional array elements by key in PHP. PHP array_multisort() function provides an easy way to sort a multidimensional array by key value. The order of an array elements can sort by key using foreach() loop, but it will be a complicated process, and execution time is high.
