提问by Daric
How can I loop through all the properties of object?. Right now I have to write a new code line to print each property of object
如何遍历对象的所有属性？现在我必须编写一个新的代码行来打印对象的每个属性
echo $obj->name;
echo $obj->age;
Can I loop through all the properties of an object using foreach loop or any loop?
我可以使用 foreach 循环或任何循环遍历对象的所有属性吗？
Something like this
像这样的东西
foreach ($obj as $property => $value)

If this is just for debugging output, you can use the following to see all the types and values as well.
如果这只是为了调试输出，您也可以使用以下命令查看所有类型和值。
var_dump($obj);
If you want more control over the output you can use this:
如果你想更多地控制输出，你可以使用这个：
foreach ($obj as $key => $value) {
echo "$key => $value\n";
}

For testing purposes I use the following:
出于测试目的，我使用以下内容：
//return assoc array when called from outside the class it will only contain public properties and values
var_dump(get_object_vars($obj));

Here is another way to express the object property.
这是表达对象属性的另一种方式。
foreach ($obj as $key=>$value) {
echo "$key => $obj[$key]\n";
}
