Question

foreach($a as $key => $value),$key不是应该在变么？

我的数组是$a = array([0] => (['name'] => aa) ['id'] => 1)
[1] => (['name'] => bb) ['id'] =>2 )
..
..
[8] =>(['name'] => rr) ['id'] =>9))
foreach($a as $key => $value)之后打印$key的值永远是8 合理么？

我现在想把数组变成
$a = array([0] => (['name'] => aa) ['id'] => 1 ['url'] =>'前面id的对应值')
[1] => (['name'] => bb) ['id'] =>2 ['url'] =>'前面id的对应值')
..
..
[8] =>(['name'] => rr) ['id'] =>9 ['url'] =>'前面id的对应值' ))
因为要用[id]的值 所以选foreach 有没有好办法呢 ？我实在是没分了

哦 应该是这样

你能用var_dump输出一下数组么，再贴图上来看看，这样我实在理解不了数据的结构，

追问

我已经解决的
非常感谢！
