分享一个简单数组问题
各位高手下面这段程序有错么？
$myphonebook = array (
"sbabu" => "5348",
"keith" => "4829",
"carole" => "4533"
);
$myphonebook["dean"] = "5397";
$myphonebook["carole"] => "4522"
echo "$myphonebook[0]"; // sbabu
echo "$myphonebook[1]"; // 5348
$myphonebook = array (
"sbabu" => "5348",
"keith" => "4829",
"carole" => "4533"
);
$myphonebook["dean"] = "5397";
$myphonebook["carole"] => "4522"
echo "$myphonebook[0]"; // sbabu
echo "$myphonebook[1]"; // 5348

这个我也不大明白，你可以搜索一下foreach用法
我的理解是一一取出 $key和其相对应的$value的值

应该为$myphonebook["carole"] = "4522"吧？
可我怎么无法输出内容呢？

$myphonebook["carole"] => "4522" 这是什么意思？
