Question

我有一个像这样的json对象：

{"Techne":{"@Version":"2.2","Author":"ZeuX","Name":"","PreviewImage":"","ProjectName":"","ProjectType":"","Description":"","DateCreated":"","Models":[{"Model":{"GlScale":"1,1,1","Name":"","TextureSize":"1,1","@texture":"texture.png","BaseClass":"ModelBase","Geometry":{"Folder":[],"Shape":[],"Piece":[],"Null":[]}}}]}}

如何使用PHP检查数组Shape：[]是否为空我只知道如何使用JavaScript但这个问题需要使用PHP我该怎么办？

您可以使用json_decode()然后访问其成员。

$json = json_decode('{"Techne":{"@Version":"2.2","Author":"ZeuX","Name":"","PreviewImage":"","ProjectName":"","ProjectType":"","Description":"","DateCreated":"","Models":[{"Model":{"GlScale":"1,1,1","Name":"","TextureSize":"1,1","@texture":"texture.png","BaseClass":"ModelBase","Geometry":{"Folder":[],"Shape":[],"Piece":[],"Null":[]}}}]}}');

if(empty($json->Techne->Models[0]->Model->Geometry->Shape))
    echo "Shape is empty";

在这种情况下，

json_decode()会给你一个对象，因为这就是这个JSON字符串的格式。您可以通过搜索JSON和PHP来了解更多信息，有很多教程可以帮助您更好地理解。

我希望它对你有所帮助。
