Checking if mysql_query returned anything or not

Question

$query = \"SELECT * FROM `table`\";
$results = mysql_query($query, $connection);

If \'table\' has no rows. whats the easiest way to check for this.?

Answer 1

One thing i noticed that was missed was the fact that the query might not succeed, so you do need to check if the $results variable is set. I'll use the answer given by yjerem as an example.

$query = "SELECT COUNT(*) AS total FROM table";
$results = mysql_query($query, $connection);
if ($results) { // or use isset($results)
$values = mysql_fetch_assoc($results);
$num_rows = $values['total'];
}
