Hello

Some of the columns are empty, and must be turned into "nbsp;" so
that an empty cell is shown when displayed in HTML.

This code, however, doesn't work (meaning: I get an empty line instead
of "nbsp;"), but I don't know how else to loop through each column in
the current row:

========
$sql = "SELECT * FROM phones";

foreach($dbh->query($sql) as $row) {

foreach($row as $key => $val) {
if(!$val)
$val="nbsp;";
}

print $row['phones_name'] . "<p>";

}
========

Any idea why?

Thank you.
