![]() The resulting array contains only the values in the sorted order. Sort( ) and rsort( ) can be used on associative arrays, but the keys are lost. The rsort() function also takes two parameters, array and sorttype value. The same optional second parameters are allowed that can be used with sort(). PHP rsort() function sorts numerical array in descending order. If you want to sort the elements of the array in reverse order (descending order), use rsort() (r for reverse). sort() can take an array of strings as argument, and sorts the elements in. However, a problem exists if the array contains both numerical and string values (for instance, "2" > "10" but 2 4 To sort an array of strings in PHP, we can use sort() or rsort() array functions. However, it will not maintain any key-value. Note: If two members compare as equal, they retain their original order. Numerical arrays can be sorted rather easily by using sort() or rsort(). You can use the sort(&array, sortflags) function to sort the values of an array from low to high. ksort (PHP 4, PHP 5, PHP 7, PHP 8) ksort Sort an array by key in ascending order Description ksort ( array &array, int flags SORTREGULAR ): true Sorts array in place by keys in ascending order. In the following example, the PHP constant SORT_STRING sorts the numbers as if they were strings: 16 An optional parameter, flag, can be passed to force the string or numeric sorting behavior. Sorts array in place by values in ascending order. The following example shows the rsort( ) function on the same array: 56īy default, PHP sorts strings in alphabetical order and numeric values in numeric order. */ Sorting Arrays in Descending Order – rsort() ![]() Both functions sort the subject array based on the values of each element. In this tutorial, we’ll discuss the sort and rsort functions. The sort function allows for the sorting of array either numerically (for numerical values) or alphabetically (for string values). foreach iterates over the input array without any modifications to the order. Also create an array merely consisting of the averageItemLevelEquipped values, and then use that as the index array when runnning arraymultisort. Because of this behavior, the sort functions must be passed a variable, not an expression. 4 Answers Sorted by: 2 I recommend creating an array out of the data you have there, with a sub-array for each person. ![]() 'email' => = array_column ( $records, 'first_name' ) Īrray_multisort ( $key_values, SORT_ASC, $records ) Īfter sorting, the $records array is returned in the following order.All sorting functions rearrange the elements in the source array itself. This function performs sorting on the given array and arranges the elements of the array in descending array, opposite of what sort() function does. In this example code snippet, the first_name key is specified to sort the $records array in ascending order.
