php解析json的问题

	<br />
$a = array(array('a','b','c','f','g'),'a'=>123);<br />
$jsonStr = json_encode($a);<br />
$e = json_decode($jsonStr);<br />
<br />
Copy after login

通过print_r打印为:
stdClass Object ( [0] => Array ( [0] => a [1] => b [2] => c [3] => f [4] => g ) [a] => 123 )
如果我想获取123的值我直接$e->a;
但我想获取0里面的值应该怎么处理啊,对象属性名为0肯定是说不同的,这种情况应该怎么取值呢?


------解决方案--------------------
echo $e->{'0'}[1]; //b

通常用 $e = json_decode($jsonStr, true); 转换成数组就比较容易处理了
echo $e[0][1]; //b
