Username Name 

Вот мой PHP код:

<?php 
$con=mysqli_connect("localhost","root","123","login"); 
// Check connection 
if (mysqli_connect_errno()) 
    { 
    echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
    } 

$result = mysqli_query($con,"SELECT * FROM users"); 

echo "<table border='1'> 
<tr> 
<th>Username</th> 
<th>Name</th> 
</tr>"; 

while($row = mysqli_fetch_array($result)) 
    { 
    echo "<tr>"; 
    echo "<td>" . $row['username'] . "</td>"; 
    echo "<td>" . $row['name'] . "</td>"; 
    echo "</tr>"; 
    } 
echo "</table>"; 

mysqli_close($con); 
?> 

Answer 1

Try mysqli_fetch_assoc ($ результат) или mysqli_fetch_array ($ результат, MYSQL_ASSOC) вместо mysqli_fetch_array ($ result)
