PHP数组到字符串问题

您好，我在PHP中有一个数组，当我打印它时，它是这样的：

["Testing","Test2","New Testing Activity","The last five letters in the alphabet"]

{"Testing","Test2","New Testing Activity","The last five letters in the alphabet"}

有没有一种方法可以使数组变成这样：

["Testing","Test2","New Testing Activity","The last five letters in the alphabet"]

{"Testing","Test2","New Testing Activity","The last five letters in the alphabet"}

我要这个“{”而不是“[”

谢谢

也许你想做：

echo '{"' . implode('","', $arr) . '"}';
