PHP數組字符串問題

Question

你好，我在PHP中的數組，當我打印出來是這樣的：

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

是有辦法使數組這樣的：

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

我要代替這個'{''['

感謝

Answer 1

也許你想做的事：

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