问题描述

我正在尝试通过以下代码访问文本"的内容.实际上，我之前曾问过几乎相同的问题，并且它已经完美地解决了. 如何访问JSON的某些部分?但是，何时我在此JSON上使用了相同的方法，但无法正常工作.

I'm trying to access the content of "text" in the following code. Actually I have asked almost the same question before and it was solved perfectly. How to access certain part of a JSON? However, when I use the same method on this JSON, it doesn't work.

$test = 
'{
    "username":"lon",
    "event":{
        "saved_response":"{\"parts\": [{\"text\": \"Passion for teaching means loving your job. Doing with all your heart. Teachers who are passionate can inspire pupils to love learning. Passionate teachers create an effective learning environment and increase learning potential of\\nstudents.\"}]}"
    },
    "event_source":"server"
}';

$jarray = json_decode($test, true);
$jevent = json_decode($jarray['event']['saved_response'], true);
var_dump($jevent);
echo $jevent['parts'][0]['text'];

输出为NULL，我不知道该怎么办.有人可以帮我吗?谢谢.

The output is NULL and I don't know what to do. Can anyone help me with it? Thanks.

久经考验的json_decode(json_encode($test), true); 为我做这份工作.干杯！

The tried and tested json_decode(json_encode($test), true); Does the job for me. Cheers!

$test = 
'{
"username":"lon",
"event":{
    "saved_response":"{\"parts\": [{\"text\": \"Passion for teaching means loving your job. Doing with all your heart. Teachers who are passionate can inspire pupils to love learning. Passionate teachers create an effective learning environment and increase learning potential of\\nstudents.\"}]}"
},
"event_source":"server"
}';

$jarray = json_decode(json_encode($test), true);

$jarray = explode('"',$jarray);

print_r($jarray[14]);
