The function of @property in PHP

What is the role of @property in PHP?
I found that after declaring the attribute with @property, the class can also be used, as in the following code! Excuse me, what's the difference between adminName1 and adminName2? is the general declaration attribute used @property?

/**
* @property String adminName1
*/

Class Test {

Private $adminName 2;

Public Function GetName ($pram 1, $pram 2) {
$this->adminname1 = $pram 1;
$this->adminname2 = $pram 2;
}
}

?>

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

@property string adminName1
Is that the attribute adminName1 is a string

This is just to help understand the program's explanatory text

You go according to its rules. Where does this code come from?

It's been said to help understand the program's explanatory text.
A change like yours
/**
* @property String adminName1
*/
There's no point in explaining it, and there's a misunderstanding.
Obviously he said there is a adminName1 attribute, why didn't I see it? Only see adminName2, is not also to define a adminName1 AH
