Prev---&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Internal metrics for moving the array backwards

Syntax: Mixed prev (array array);

Description:

Returns the array element that the internal metric of the previous array refers to, and returns false if there are no previous elements.

Warning: If an array contains empty elements, this function returns FALSE, and you can use each () function to process an array containing empty elements.

This function is similar to next (), and Prev () moves the internal metric of the array backwards to replace the forward movement of next ().

Reference: Current () End () Next () Reset ()
