$mysqli = new mysqli('localhost', 'root', '12345678', 'mysql');
if ($mysqli->connect_errno) {
echo "Can't connect to mysqld (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
echo 'Connected successfully';
$res = $mysqli->query("SELECT * FROM user");
echo "<table>\n";
while ($line = $res->fetch_assoc()) {
echo "\t<tr>\n";
foreach ($line as $col_value) {
echo "\t\t<td>$col_value</td>\n";
}
echo "\t</tr>\n";
}
echo "</table>\n";

<?php
$link = mysql_connect('localhost', 'root', '') or die('Could not connect: ' . mysql_error());
echo 'Connected successfully';
mysql_select_db('mysql') or die('Could not select database');
$query = 'SELECT * FROM user';
$result = mysql_query($query) or die('Query failed: ' . mysql_error());
echo "<table>\n";
while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {
echo "\t<tr>\n";
foreach ($line as $col_value) {
echo "\t\t<td>$col_value</td>\n";
}
echo "\t</tr>\n";
}
echo "</table>\n";
mysql_free_result($result);
mysql_close($link);
?>
