PHP ARRAY FUNCtIONS

PHP has a great deal of support for working with arrays built in. There are many string functions built into PHP-and there are plenty of arrays functions as well. You can see them in below:

Functions	Does This
array_change_key_case	Returns an array with all string keys converted to lowercase or uppercase
array_chunk	Splits an array into chunks
array_combine	Creates an array by using one array for the keys and another for the values
array_count_value	Counts the values in an array
array_diff_assoc	Computes the difference of two arrays with additional index check
array_diff_uassoc	Computes the difference of two arrays with additional index check, performed by a user-supplied callback function
array_diff	Computes the difference of arrays
array_fill	Fill an array with values
array_filter	Filter elements of an array using a callback function
array_flip	Exchange all key with their associated values in an array
array_intersect_assoc	Computes the intersection of arrays with additional index check
array_intersect	Computes the intersection of array
array_key_exists	Check if the given key or index exists in the array
array_keys	Returns the key in an array
array_map	Applies the callback to the elements of the given arrays
array_merge_recursive	Merges two or more arrays recursively
array_merge	Merges two or more arrays
array-multisort	Sort Multiple or Multidimensional arrays
array_pad	Pad array to the specified length with a value
array_pop	Pops the element off the end of array
array_push	Pushes one or more random elements out of an array
array_rand	Picks one or more random elements out of an array
array_reduce	Reduces the array to a single value with a callback function
array_reverse	Returns ana array with elements in reverse order
array-search	Searches the array for a given value and returns the corresponding key
array_shift	Shifts an element off the beginning of an array
array_slice	Extract a slice of the array
array_splice	Remove part of the aray and replace it with something else
array_sum	Calculates the sum of values in an array
array_udiff_assoc	Computes the difference of arrays with an additional index check. Here, the data is compared by using a callback function
array_udiff_uassoc	Computes the difference of arrays with an index check. Here, the data is compared by using a callback function, and the index check is also performed by callback function
array_udiff	Computes the difference between arrays by using a callback function
array_unique	Remove duplicate elements from an arrays
array_unshift	Adds one or more elements to the beginning of an array
array_values	Returns all the values of an array
array_walk	Calls a user-supplied function on every member of an array
array	Create an array
arsort	Sorts an array in order, preserving index association
asort	Sort and array and maintains index association
compact	Creates array containing variables and their values
count	Counts the elements in an array
current	Returns the current element in an array
each	Returns the current key and values pair an array and advances the array cursor
end	Sets the array pointer to the last elements
extract	Imports variables into the current symbol table from an array
in_array	Check if the value exists in an array
key	Gets a key from an associative array
krsort	Sorts an array by key in reverse order
ksort	Sorts an array by key
list	Assigns variables as if they were an array
natcasesort	Sorts an array using a case-insensitive "natural order" algorithm
natsort	Sorts an array using a "natural order" algorithm"
next	Advances the array pointer of an array
pos	Alias of the current function
prev	Moves the array pointer back on elements
range	Creates an array containing a range of elements
reset	Sets the pointer of an array to its first elements
rsort	Sorts an array in reverse order
shuffle	Shuffles an array's elements
sizeof	Alias of the count function
sort	Sorts an array
uasort	Sorts an array with a user-defined comparison functions, maintaining indexes
uksort	Sorts an array bby keys; uses a user-defined comparison function
usort	Sorts an array by values; uses a user-defined comparison function
