Can anyone tell me what to do next? Thanks!

$test =

    },
    "event_source":"server"
}';

$jarray = json_decode($test, true);
echo $jarray['event']['response'];

推荐答案

您的json数据在此处无效:-

you json data is invalid here:-

"{\"parts\": [{\"text\": \"Passion\"]}" 
//----------------------------------^ one } needed before ]

更正输入后，请执行以下操作:

After correcting the input do like below:

<?php

$test = 
'{
    "event":
    {
        "response":"{\"parts\": [{\"text\": \"Passion\"}]}"
    },
    "event_source":"server"
}';

$jarray = json_decode($test, true);

print_r($jarray);

$response = json_decode($jarray['event']['response'], true);

echo $response['parts'][0]['text'];
