我想获取 PHP 数组中的下一个值,例如:
$array = array('a', 'b', 'c', 'd', 'e', 'f');
$current_array_val = 'c';
//so I want to run a code to get the next value in the array and
$next_array_val = 'd';
//And also another code to get the previous value which will be
$prev_array_val = 'b';
请问我如何运行我的代码来实现此目的
最佳答案
http://php.net/manual/ro/function.array-search.php
$index = array_search($current_array_val, $array);
if($index !== false && $index > 0 ) $prev = $array[$index-1];
if($index !== false && $index < count($array)-1) $next = $array[$index+1];
