我是编码领域的新手，正在尝试从给定的JSON文件中检索特定值，并将其存储为PHP变量，然后将其添加到SQL数据库中。
我已经阅读了大约六本教程，而且它们似乎只深入了一层，并从中获得了价值。
我正在尝试获取php中的粗体值。
功能{“属性”：{“ Master_Incident_Number”：“ QF2-19-097369 ”，“ IncidentType”：“ 植被大火”...。
是否有可能，如果有人可以，请帮助我指出这一点。
谢谢
答案 0 :(得分：0)
使用map遍历features.attributes以访问键Master_Incident_Number和IncidentType。
