I found that the following code can also be used in the class after I declare the property with @ property! What is the difference between adminName1 and adminName2? Is it generally stated that all attributes use @ property?

/**
* @ Property string adminName1
*/

Class test {

Private $ adminName2;

Public function getName ($ pram1, $ pram2 ){
$ This-> adminName1 = $ pram1;
$ This-> adminName2 = $ pram2;
}
}

Didn't you see that he was in the comment?

@ Property string adminName1
Indicates that the property adminName1 is a string.

This is just to help understand the instructions of the program

You can follow the rules. Where is the code from?
------ Solution --------------------
I have already said it is to help understand the instructions of the program.
Change like you
/**
* @ Property string adminName1
*/
There is no meaning to explain. On the contrary, there will be misunderstandings.
Clearly, he said there was an adminName1 attribute. Why didn't I see it? Only adminName2 is displayed. do you want to define an adminName1?
