mysql_select_db("bookorama", $con);
$sql="SELECT * FROM customers";
$result = mysql_query($sql); // You actually have to execute the $sql with mysql_query();
echo "<table>"; //start the table
while($row = mysql_fetch_array($result, MYSQL_ASSOC)) //Loop through the results
{
//echo each row of the table
echo "<tr>

Answer 2

You can mysql_fetch_array or mysql_fetch_assoc to retriever the rows from you query.
For example using mysql_fetch_array:
$result = mysql_query($sql);
echo "<table><tbody>";
while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
echo "<tr><td>".$row[0] . "</td><td>" . $row[1] . "</td></tr>";
}
echo "</tbody></table>"

Answer 3

You need to run the query and loop through the results.
You are better off learning from day one about PDO.
And also don't interpolate directly from any user submitted variables (that includes $_POST).

Answer 4

Pretty sure you need to do this when embedding anything more complex than scalars inside double quotes
echo "<tr>
<td>{$row['CustomerID']}</td>
<td>{$row['address']}</td>
<td>{$row['city']}</td>
</tr>";
So whenever you have a more complex var name than "test $var" in quotes, wrap with {} - and even then, it's good practice to wrap scalars too like "test {$var}"
