将字符串转换为JSON

Question

有没有办法让PHP将string视为JSON？ 我有一个string，当然是JSON格式，我想对它执行操作，就像它是一个数组一样。但是我不想使用CJSON::decode，因为它需要很长时间，有办法吗？ 字符串示例：

{"myArray":[{"key1":"val1","key2":"val2","key3":"val3","key4":"val4"},
{"key1":"val2_1","key2":"val2_2","key3":"val2_3","key4":"val2_4"}]}

Answer 1

json_decode()怎么样？

我认为没有比那更快的

$string = '{"myArray":[{"key1":"val1","key2":"val2","key3":"val3","key4":"val4"},    {"key1":"val2_1","key2":"val2_2","key3":"val2_3","key4":"val2_4"}]}';
$array = json_decode($string);

Answer 2

不确定CJSON :: decode是什么，但您必须解码字符串，以便您可以使用内置函数json_decode($str);
