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

$pig =new animal ();
$pig->setinfo (' pig ');//This is the wrong line, your semicolon is the full-width semicolon.
$name = $pig->getinfo ();//Compiler hint Error
Echo $name;

/**
In addition: After the code, the format of it
*/

------Solution--------------------
The previous line is a full-width semicolon?
------Solution--------------------

 
  Class person{
    Private $name;
    
    function SetName ($name) {
        return $this->name = $name;
    }
    
    function GetName () {
        return $this->name;
    }
}
$p = new Person ();
$p->setname (' Lizhi ');
echo $p->getname ();
?>

------Solution--------------------
Why did you get the error?
is because you have a capital semicolon in line 10th,

Why didn't you export "pig"?
Give it a try
function SetInfo ($name) {return $this->name;} Compiler prompt Warning
Change into
function SetInfo ($name) {$this->name = $name;} The compiler prompts the police
------Solution--------------------

Class animal{
  Public $name = "";
  Public $color = "";
  Public $age = "";
  function GetInfo () {
    return $this->name;
  }
  function SetInfo ($name) {
    $this->name = $name; This is supposed to be an assignment, you must have copied it wrong.
  }
}
$pig =new animal ();
$pig->setinfo (' pig '); It turned out to be full-width;
$name = $pig->getinfo ();
Echo $name;
