- $switching = array(
- 10, // key = 0
- 5 => 6,
- 3 => 7,
- 'a' => 4,
- 11, // key = 6 (整个数组中整型键索引最大的值是5)
- '8' => 2, // key = 8 (字符串健'8'转换为8)
- '02' => 77, // key = '02'(注意不是2)
- 0 => 12
- /*前面值为10的键被赋予0,而后面重新定义了0键的值为12,
- 从而覆盖了前面默认的0键值*/
- );
- // empty array
- $empty = array();
- ?>
-
如果用print_r($switching)打印出来的话结果为:
Array ( [0] => 12 [5] => 6 [3] => 7 [a] => 4 [6] => 11 [8] => 2 [02] => 77 )
注意,两位数的02被排在后面。 |
