用php从数据库中获取数据

Question

I want to get the data from my database. The page does not change when I upload the file. Where am I wrong?

verifycheck.php

<?php
$con=mysql_connect ("###", "###", "###");
mysql_select_db ("db_name", $con);


$result = mysql_query($con,"SELECT * FROM db_tablename");


echo "<table border='1'>
<tr>
<th>username</th>
<th>email</th>
<th>password</th>
<th>confirm_password</th>
</tr>";

while($row = mysql_fetch_assoc($result)) {
  echo "<tr>";
  echo "<td>" . $row['username'] . "</td>";
  echo "<td>" . $row['email'] . "</td>";
  echo "<td>" . $row['password'] . "</td>";
  echo "<td>" . $row['confirm_password'] . "</td>";
  echo "</tr>";
}

echo "</table>";

mysql_close($con);
?>

Answer 1

Remove $con, from the mysql_query

As mysql_query() expects first parameter to be the SQL Query, not the SQL connection.

$result = mysql_query("SELECT * FROM db_tablename");
