本文这里通过示例给大家简单对比分析了PHP 数组current和next的用法,虽然示例很简单,但是对于我们理解current和next非常有帮助,这里推荐给大家。
1.current
< php $transport = array('foot', 'bike', 'car', 'plane'); $mode = current($transport); //$mode = 'foot'; $mode = next($transport); // $mode ='bike'; $mode = current($transport); //$mode = 'bike'; $mode = prev($transport); // $mode ='foot'; $mode = end($transport); // $mode ='plane'; $mode = current($transport); //$mode = 'plane'; >
2.next
< php $transport = array('foot', 'bike', 'car', 'plane'); $mode = current($transport); //$mode = 'foot'; $mode = next($transport); // $mode ='bike'; $mode = next($transport); // $mode ='car'; $mode = prev($transport); // $mode ='bike'; $mode = end($transport); // $mode ='plane'; >
示例很简单,但是却很实用,希望小伙伴们能够喜欢。
