array_helper.php

Searches an array through dot syntax. Supports wildcard searches, like foo.*.bar

Returns the value of an element at a key in an array of uncertain depth.

Sorts a multidimensional array by its elements values. The array columns to be used for sorting are passed as an associative array of key names and sorting flags. Both arrays of objects and arrays of array can be sorted. Example: array_sort_by_multiple_keys($players, [ 'team.hierarchy' => SORT_ASC, 'position' => SORT_ASC, 'name' => SORT_STRING, ]); The '.' dot operator in the column name indicates a deeper array or object level. In principle, any number of sublevels could be used, as long as the level and column exist in every array element. For information on multi-level array sorting, refer to Example #3 here: https://www.php.net/manual/de/function.array-multisort.php after and their sorting flags

Flatten a multidimensional array using dots as separators.

Groups all rows by their index values. Result's depth equals number of indexes
