Ask elder sister to help little brother I look at this program what is wrong

Please, brother elder sister, help me see what's wrong with this program.
Create a user class with "name", "School Number", "Age", "contact phone" Four private attributes that require the assignment of a property "name" through a constructor, and other properties are assigned and accessed through the method. Print out the information for the user "Zhang San", "200440132" "21", "63886666".
Class Message
{
Private $name;
Private $num;
Private $age;
Private $tel;

function __construct ($name, $num, $age, $tel)
{
$this->name= $name;
$this->num= $num;
$this->age= $age;
$this->tel= $tel;
}
function Say ()
{
echo "User:" $this->name "
School Number: "$this->num"
Age: "$this->age"
Tel: "$this->tel;
}
$p =new Message ("Zhang San", 200440132,21,63886666);
$p->say ();
?>

------Solution--------------------

PHP Code

function Say () {echo "User:". $this->name. " 
 Study Number: ". $this->num." 
 Age: ". $this->age." 
 Contact Phone: $this->tel;//There is no use here}} Inside not closed, less curly braces $p=new Message ("Zhang San", 200440132,21,63886666); 
------Solution--------------------
 Echo User: $this->name. "

 Age: ". $this->age." 
 Contact Phone: $this->tel;
