array values, and returns the differences 4 array_diff_assoc() Compares array keys and values, and returns the differences 4 array_diff_key() Compares array keys, and returns the differences 5 array_diff_uassoc() Compares array keys and values, with an additional user-made function check, and returns the differences 5 array_diff_ukey() Compares array keys, with an additional user-made function check, and returns the differences 5 array_fill() Fills an array with values 4 array_filter() Filters elements of an array using a user-made function 4 array_flip() Exchanges all keys with

selected parts of an array 4 array_splice() Removes and replaces specified elements of an array 4 array_sum() Returns the sum of the values in an array 4 array_udiff() Compares array values in a user-made function and returns an array 5 array_udiff_assoc() Compares array keys, and compares array values in a user-made function, and returns an array 5 array_udiff_uassoc() Compares array keys and array values in user-made functions, and returns an array 5 array_uintersect() Compares array values in a user-made function and returns an array 5 array_uintersect_assoc() Compares array keys, and compares array values in a user-made function, and returns an array 5 array_uintersect_uassoc() Compares array keys and array values in user-made functions, and returns an array 5 array_unique()

function to every member of an array 3 array_walk_recursive() Applies a user function recursively to every member of an array 5 arsort() Sorts an array in reverse order and maintain index association 3 asort() Sorts an array and maintain index association 3 compact() Create array containing variables and their values 4 count() Counts elements in an array, or properties in an object 3 current() Returns the current element in an array 3 each() Returns the current key and value pair from an array 3 end() Sets the internal pointer of an array to its last element 3 extract() Imports variables
