Newcomer: Why can't I assign a value and output to the private field through _get () and _set ()?
Example:





Class Employee {
Private $name;

function _get ($propName) {
echo "_get called!
"; and cannot output any strings

return $this $propName;
}

function _set ($propName, $propValue) {
$this $propName = $propValue;
}
}

$employee = new Employee ();
$employee->name = "Mario";

echo $employee->name. "
";
?>



Why is it like this? What parameters do you want to open?

------Solution--------------------
function _get ($propName) {
echo "_get called!
"; and cannot output any strings

return $this $propName;
}
Isn't there only one underline for red?
The Magic function name that implements this function is __get
is two underline
