MySQL/PHP connection ok, sql statement doesn't work - php

Question

How can I get this to echo or print out the results of a select statement via php?
<?php
$username = "root";
$password = "root";
$hostname = "localhost";
//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
echo "Connected to MySQL<br>";
?>
<?php
$query="SELECT * FROM mydb.product";
$result=mysql_query($query);
echo "$result";
echo $result;
?>
I've gotten this far now, but it still returns nothing. Does the problem lie within my mysql table? Or does it fall somewhere else
<?php
$username = "root";
$password = "root";
$hostname = "localhost";
//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
echo "Connected to MySQL<br>";
$sth = $db->prepare("SELECT * FROM mydb.test;");
$sth->execute();
$result = $sth->fetchAll();
?>
<h1> Im here</h1>
<?php
foreach ($result as $row) {
echo "<tr>";
echo "<td>{$row['name']}</td>";
echo "<td>" . $row['email'] . "</td>";
echo "</tr>";
}
?>
<h1> Im still here</h1>
Thanks for all the help

Answer 1

You need to look through the results. If there are, say, 3 columns in each row then your code would look something like this:
for($i=0;$i<mysql_num_rows($result);$i++) {
$row_array=mysql_fetch_row($result);
echo($row_array[0]." ".$row_array[1]." ".$row_array[2]."<br />");
}

Answer 2

As suggested in the comments, you'll have to loop through the fetched results:
$query="SELECT * FROM mydb.product";
$result=mysql_query($query);
// Add these lines:
while ($row = mysql_fetch_assoc($result)) {
var_dump($row);
// each item from the row could be used like this:
// echo $row['field'];
}

Please note that mysql_query is depricated, and you should consider switching to mysqli (http://php.net/manual/en/book.mysqli.php) or PDO (http://php.net/manual/en/ref.pdo-mysql.php)
