php改变数组键名的方法：首先创建PHP示例文件；然后通过“array_combine”以及“array_walk”等方法实现修改数组键名的功能；最后用“print_r”方法打印出修改后的结果即可。
php修改数组键名的方法
$ar = array(
array(1 => 'a', 2 => 50, 3 => 60, 4 => 'long', 5 => 'zzz', 6 => 'kkk', 7 => 'ooo'),
array(1 => 'b', 2 => 60, 3 => 70, 4 => 'king', 5 => 'lll', 6 => 'ttt', 7 => 'ppp'),
array(1 => 'c', 2 => 70, 3 => 80, 4 => 'quit', 5 => 'qqq', 6 => 'xxx', 7 => 'ccc'),
);
$kname = array('StaffId', 'Wage', 'Name', 'Work', 'Type');
function foo(&$v, $k, $kname) {
$v = array_combine($kname, array_slice($v, 1, -1));
}
array_walk($ar, 'foo', $kname);
print_r($ar);运行结果为：
Array
(
[0] => Array
(
[StaffId] => 50
[Wage] => 60
[Name] => long
[Work] => zzz
[Type] => kkk
)
[1] => Array
(
[StaffId] => 60
[Wage] => 70
[Name] => king
[Work] => lll
[Type] => ttt
)
[2] => Array
(
[StaffId] => 70
[Wage] => 80
[Name] => quit
[Work] => qqq
[Type] => xxx
)
