current函数

## PHP current()函数 **(**PHP current() function**)** ##

An array in PHP has a current pointer which points to the first element by default, **current() function** is used to get the current elements of an array. It accepts an array and returns its current element.

PHP中的数组具有当前指针，该指针默认情况下指向第一个元素， **current()函数**用于获取数组的当前元素。 它接受一个数组并返回其当前元素。

**Syntax:**

**句法：**

current(array);

**Note:**

**注意：**

*  In an array which contains keys and values, it returns only value not a key.
    
    在包含键和值的数组中，它仅返回值，而不返回键。
 *  **current()** returns only the current element, it does not move the pointer to next element.
    
    **current()**仅返回当前元素，它不会将指针移动到下一个元素。

        $arr1 = array(10, 20, 30, 40, 50);
