I'm trying to figure out something. I found some calendar making code. For each table cell, I want to add <a href="">$day</a> around $day if an entry exists in $db.$table

$sql = 'SELECT * FROM '.$db.'.'.$table.' where eventid like '.$eventid.';';

if ($sql ??)
 

This will do:

   if ($sql)

Best

Bao

{echo "<td><a href=\"\">$day</a></td>";
}else{
echo "<td>$day</td>";
}
How do I code to know if $sql has returned something?
Thanks,
John
P.S. Greg,
Thanks. I'm going to try to do this on my own.
If not, I will look at that. Thanks much for the reply.
