['C_19']['aweme']['detail']['video']['playAddr'][0]['src']
['C_19']['aweme']['detail']['video']['playAddr'][1]['src']

跟前面大哥一样，就是一层一层获取，很容易的

数据["C_19"]["aweme"]["detail"]["video"]["playAddr"][0]['src']
一层一层获取就行了

是不是必须要用$arr=json_decode($json_string,true); 将json格式数据转化成数组形式，才能用你的方式读取，是吗？

我是逸先生 · 发表于 2021-10-16 07:55

也可以不转化成数组，echo $json_string->C_19->aweme->detail->video->playAddr->0->src
但是最好转化，用起来方便

用您的方法，我的代码如下：
echo $realdata->C_19->aweme->detail->video->playAddr->0->src;
出错信息如下：
Parse error: syntax error, unexpected '0' (T_LNUMBER), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in D:\phpStudy\PHPTutorial\WWW\1.php on line 82

请问是什么情况
