This indicates a php version incompatibility with mysql libraries installed on your webhost.
Contact server administrator to resolve the issue.

thank for reply.

But when im trying to use this code:

$mysqlConnection = mysqli_connect($server, $username, $password,$database);
if (!$mysqlConnection)
{
die('Could not connect: ' . mysql_error());
}
$query = mysql_query("select * from user");

while ($row = mysql_fetch_assoc($query)) {
echo $row['username'];
}
mysqli_close($mysqlConnection);

this can bring me with the result, is it cause by other problem beside php incompatibility with mysql?
i also try to use the requirement detail that is look like no problem.

Attached File(s)

Something's wrong with PDO?..
Try this instead:

$mysqlConnection = new PDO("mysql:host=...;dbname=...", $username, $password);

Next steps depend on how much access do you have to your server.
Here's similar thread with solutions.
