# array_slice()array_slice()

## 语法Syntax

array_slice( arr , start , end )array_slice( arr , start , end )

## 参数Arguments

• arr ：要从中提取切片的输入数组必须是动态数组。arr : Input array to extract the slice from must be dynamic array.
• start：切片的从零开始（包括零）的开始索引，负值转换为 array_length+start。start : zero-based (inclusive) start index of the slice, negative values are converted to array_length+start.
• end：切片的从零开始（包括零）的结束索引，负值转换为 array_length+end。end : zero-based (inclusive) end index of the slice, negative values are converted to array_length+end.

## 返回Returns

arr 中处于 [start..end] 范围内的值的动态数组。Dynamic array of the values in the range [start..end] from arr.

## 示例Examples

print arr=dynamic([1,2,3])
| extend sliced=array_slice(arr, 1, 2)
arr sliced
[1,2,3][1,2,3] [2,3][2,3]
print arr=dynamic([1,2,3,4,5])
| extend sliced=array_slice(arr, 2, -1)
arr 已切片sliced
[1,2,3,4,5][1,2,3,4,5] [3,4,5][3,4,5]
print arr=dynamic([1,2,3,4,5])
| extend sliced=array_slice(arr, -3, -2)
arr 已切片sliced
[1,2,3,4,5][1,2,3,4,5] [3,4][3,4]
