Question

php 修改数组内的值

Array
(
[params] => Array
(

[siteId] => 1
[Html] => 0
[setRss] =>
[logo] => moren.gif
[on_off] => 1
[navId] => 0
[publishNum] => 1
[indexNum] => 10
[pageNum] => 10
[tagNum] => 20
[linkType] => linkTaobao
[publishTime] => 20:00:00
[keyLinkNum] => 2
)

)

logo的值不是固定的，不能用直接替换more.gif的方法！把这个数组里面的 logo 值更改为 touxiang.jpg，

重新返回数组 ，请问咋写 php代码的

Answer 1

你原本的语法错了不少，我帮你改了
$a=array
(
"params" => array
(
"siteId" => "1",
"Html" => "0",
"setRss" =>"",
"logo" => "moren.gif",
"on_off" => "1",
"navId" => "0",
"publishNum" => "1",
"indexNum" => "10",
"pageNum" => "10",
"tagNum" => "20",
"linkType" => "linkTaobao",
"publishTime" => "20:00:00",
"keyLinkNum" => "2",
)
);
$a['params']['logo']="touxiang.jpg";
print_r($a);

Answer 2

$a['params']['logo'] = touxiang.jpg;

Answer 3

$arr = '你的数组'；
$arr[params][logo] = touxiang.jpg;
print_r($arr);
