If empty variable - php

Question

I'm using the code below:
<?php
$sql = "SELECT * FROM nieuws ORDER BY id DESC LIMIT 0, 3";
$results = $db->query($sql);
if (empty($results)) {
echo 'Momenteel geen nieuws.';
}
foreach ($results as $row)
{
echo '<h3>';
echo $row['titel'].'<br>';
echo '</h3>';
echo $row['bericht'].'<br>';
echo '<br><br><div style="float: left;"><small>Schrijver: '.$row['schrijver'].'</small></div>';
echo '<div style="float: right; margin-bottom:-20px;">Lees meer...</div><br><br><hr>';
}
?>
This code will fetch information from the database. But if there is nothing in a table, it needs to say 'Momenteel geen nieuws.'.
It doesn't say that, and i don't understand why it doesn't...
If there is somebody who can help me out, it would be very nice!

<?php
$sql = "SELECT * FROM nieuws ORDER BY id DESC LIMIT 0, 3";
$results = $db->query($sql);
if (count($results) < 1) {
echo 'Momenteel geen nieuws.';
}else
{
foreach ($results as $row)
{
echo '<h3>';
echo $row['titel'].'<br>';
echo '</h3>';
echo $row['bericht'].'<br>';
echo '<br><br><div style="float: left;"><small>Schrijver: '.$row['schrijver'].'</small></div>';
echo '<div style="float: right; margin-bottom:-20px;">Lees meer...</div><br><br><hr>';
}
}
?>

Answer 2

It's not empty even with no results. You can try count() instead perhaps?
if (count($results) <1 ) {
echo 'Momenteel geen nieuws.';
}
A variable is considered empty if it does not exist or if its value
equals FALSE.

Try this
<?php
$sql = "SELECT * FROM nieuws ORDER BY id DESC LIMIT 0, 3";
$results = $db->query($sql);
if (!$results) {
echo 'Momenteel geen nieuws.';
}//end if
else{
foreach ($results as $row){
echo '<h3>';
echo $row['titel'].'<br>';
echo '</h3>';
echo $row['bericht'].'<br>';
echo '<br><br><div style="float: left;"><small>Schrijver: '.$row['schrijver'].'</small></div>';
echo '<div style="float: right; margin-bottom:-20px;">Lees meer...</div><br><br><hr>';
}//end foreach
}//end if else
?>
