// the columns using the edb_colcount() function

$con = edb_connect("type=remote;charset=Ansi;address=127.0.0.1;"+
                   "uid=Administrator;pwd=EDBDefault;database=Test");

$cmd = edb_prepare($con,"SELECT * FROM customer WHERE State=:State");
edb_setparam($cmd,"State","FL");
$cursor = edb_execute($cmd);

echo "<table border=\"1\" cellpadding=\"3\">";

echo "<tr>";

// Dump out the column headers

for ($i = 0; $i < edb_colcount($cursor); $i++)
   {
   $colinfo = edb_colinfo($cursor,$i);
   echo "<td>" . $colinfo["Name"] . "</td>";
   }

echo "</tr>";

// Now dump out the rows

while (!edb_eof($cursor)):
   echo "<tr>";
   for ($i = 0; $i < edb_colcount($cursor); $i++)
      {
      $col = edb_getcol($cursor,$i);
      if (is_null($col))
