PHP and ecmascript_5_ Common array-related functions

	Php	ECMAScript
Length	$length = count ($array)	Length = Array.Length
Increase	Array_unshift ($array, NEW1,NEW2) adds one or more elements at the beginning, returning the length	Array.unshift (NEW1,NEW2)
	Array_push ($array, new1,new2) The tail adds one or more elements, returning the length	Array.push (NEW1,NEW2)
By deleting	Array_shift ($array) Delete and return the first element	Array.shift ()
	Array_pop ($array) Delete and return the last element	Array.pop ()
Check	In_array (value, $arrary) to see if the element is in the array $arr
Pointer	Key ($array) Gets the subscript that the current array pointer points to
	Array_keys ($array) gets all the subscript of the element, returns the index value
	Current ($array) gets the element that is pointed to by this array pointer
	Array_values ($array) to convert an associative array to an indexed array
	The Pre ($arr) returns the previous element pointed to by the current pointer, and the pointer moves forward
	Next ($arr) returns the last element pointed to by the current pointer, and the pointer moves back
	Reset ($arr) resets the pointer to the first element and returns the first element
	End ($arr) resets the pointer to the end element and returns the end element
Order	Array_reverse ($array, [True/false]) reverses the array, by default true, preserving the original key name	Arr.reverse () array inversion, changing the original array
	Sort ($array, sorttype) sorted in ascending order, regenerate key name, SortType sort mode	Arr.sort (sortby) SortBy Optional sort order, must be a function
	Shuffle ($array) scrambled array
Merge	Implode (separator, $array) array connection is string, default Separateor is empty	Arr.jion (separator) separator that the comma
	Array_merge ($arr 1, $arr 2, $arr 3) index subscript full reset, associated subscript same latter covering the former	Arr1.contact (ARR2,ARR3)
	Note: $arr 1+ $arr 2 array Merge, the subscript is the same, the latter ignores
Intercept	Array_slice ($array, start, [length], [True/false]) returns an array of specified position lengths, by default true to hold the key name	Arr.slice (start, [end]) returns an array of the specified positions
Delete/Add	Array_splice ($array, start, [Length],[array]) deletes the specified position length element and adds a new array	Arr.splice (start, length, [value1,value2]) added as an element, returning the array of elements that were deleted
New	Range (min, max, [step]) generates an array from min to max, increasing the cloth width to step
	Array_rand ($array, N) randomly extracts the subscript of n elements in the specified array
Traverse	foreach ()/list () mates each ()	For in
