Array_search--Searches the array for a given value and returns the corresponding key name if successful

Array_shift--Move the cell at the beginning of the array to a group

Array_slice--take a paragraph out of an array

Array_splice--Remove part of the array and replace it with other values

Array_sum--computes the and of all the values in the array

ARRAY_UDIFF_ASSOC--the difference set of the computed array with index check, compare data with the callback function

ARRAY_UDIFF_UASSOC--the difference set of an array with an index check to compare data and indexes with a callback function

Array_unique--Removing duplicate values in an array of divisors

Array_unshift-Inserts one or more cells at the beginning of the array

Array_values--Returns all the values in the array

Array_walk_recursive--recursively apply user functions to each member in an array

Array_walk--Applying user functions to each member in an array

Array--Creates a new array

Arsort--To reverse-sort the array and keep the index relationship

Asort--Sort the array and keep the index relationship

Compact--Create an array that includes variable names and their values

Count (sizeof)--counts the number of cells in an array or the number of attributes in an object

Current--Returns the active cell in the array

Each--Returns the current key/value pair in the array and moves the array pointer one step forward

End--Points the array's internal pointer to the last cell

Extract--Import a variable from an array into the current symbol table

In_array--Check if a value exists in the array

Key--Gets the key name from the associative array

Ksort--sorting arrays by key name

List--Assign the values in the array to some variables

Natcasesort--Using the "natural sort" algorithm to sort the case-insensitive letters of the array

Natsort--Sorting the array with the "natural sort" algorithm next--Moves the internal pointer in the arrays forward one

POS--alias Prev of current ()--Returns an array's internal pointer back to a range--creates an array containing the specified range of cells
