Order by rand(). Put first row in the end - php

Question

Is this possible somehow?:
Select all rows ( order by rand() )
Make a while loop that outputs all rows except the first one
$sql = 'SELECT id, name FROM tablename ORDER BY rand ()';
$stmt = $conn->query($sql);
while ($row = $stmt->fetch_assoc()) {
// IF NOT FIRST ROW, DO THIS
$text .= '<p>' . $row['id'] . '<br />' . $row['name'] . '</p>';
}
And then include the excluded row at end
$text .= '<p>' . $FIRSTROW_id . '<br />' . $FIRSTROW_name . '</p>';

Answer 1

Create a count and if it's first value, save it in variable.
Then, after loop, you use your variable with data from first row.
$sql = 'SELECT id, name FROM tablename ORDER BY rand ()';
$stmt = $conn->query($sql);
$i = 0;
while ($row = $stmt->fetch_assoc())
{
if ( $i == 0 )
$firstrow = $row;
else
$text .= '<p>' . $row['id'] . '<br />' . $row['name'] . '</p>';
$i++;
}
if ( $firstrow )
$text .= '<p>' . $firstrow['id'] . '<br />' . $firstrow['name'] . '</p>';
EDIT : From what you said in comments, you can just pass first row as param in AJAX and exclude it in your query :
$sql = "SELECT id, name FROM tablename WHERE id != '".intval($_GET['id'])."' ORDER BY rand ()";
$stmt = $conn->query($sql);
$_GET['id'] will be param you send by AJAX.
