Php embedded in html has garbled characters, and the simplest php program is useless. how can this problem be solved?

Php embedded in html is garbled, and the simplest php program cannot use PHPcode & lt; html & gt; & lt; head & gt; & lt; title & gt; connect. php & lt;/title & gt; & lt;/head & gt; & lt; body & gt; php embedded in html contains garbled characters, and the simplest php program is useless.

PHP code

    connect.php    This is true.">ÕâÊǸö³¬Á´½Ó
  
  
            
   
   
 
    
 
     
rrrrrr
 
     
hhhhhh
 
    
 
   
  
  
  $b){            $a++;        }        $c=$a+$b;        echo "a+b=".$c;?>

I am here only

PHP code

  
  $b){            $a++;        }        $c=$a+$b;        echo "a+b=".$c;?>

Yes
Or

PHP code

      This is true."> Super connection

It can also be displayed,
However

PHP code

  
  
  
            
   
   
 
    
 
     
rrrrrr
 
     
hhhhhh
