PHP在for循环里怎么给数组修改键值

怎么把键名 改成 键值 如:[0] = >广州始 改成 [广州] = > 0

Answer 1

array_slice($arr,1,-1);截取出来再改;
参考例子，完整写法：
$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);

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
)

)

Answer 2

按照你的图所示，应该这样写

$Line[$huoche[$i]] = $i;

Answer 3

很简单的。稍稍改下就可以了

<?php
$line[str_replace(array('始','终'),'',$huoce[$i])] = $i;

?>

Answer 4

$Line[$huoche[$i]]=$i;[]
