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

You could use mysql_num_rows($results) to check if 0 rows were returned, or use this faster alternative:

$query = "SELECT COUNT(*) AS total FROM table";
$results = mysql_query($query, $connection);
$values = mysql_fetch_assoc($results);
$num_rows = $values['total'];
