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

If you loop through the results, you can have a counter and check that.

$x = 1;
$query = mysql_query("SELECT * FROM table");
while($row = mysql_fetch_assoc($query))
{
  $x++;
}
if($x == 1)
{
  //No rows
}
