Question

Ich versuche, Echo in diesem Code zu verwenden

    require 'connect.php';
    $query = mysqli_query($conn, "SELECT * FROM `videos`") or die(mysqli_error());
    while($fetch = mysqli_fetch_array($query)){
           $id= $fetch['id'];

您可以转义字符串并将变量连接到您希望的位置，如下所示：

    
        

        

            
            

                
 
                    

                    

                        

                            
                        
                        

                            
                        
                    
                
            
        
    
        
    "; ?>
