How to manipulate query result in PHP to repeat first row - php

Question

How can i echo the first row of a query result 2 or more times, outside and inside of the while loop?
The following code just echo the first row outside of loop and doesn't allow to echo again inside of loop
case '1':
$db->Query("SELECT titulo_video,subtitulo_video,youtube_id,nome_norma FROM videos");
echo "<h2>" . $db->Row()->nome_norma . "</h2>";
while ($row = $db->Row()) {
echo "<h3>" . $row->titulo_video . "</h3>";
echo "<p>" . $row->subtitulo_video . "</p>";
}
break;
I want the data as follows:
<h3>row 1 - colum 1</h3>
<h2>row1 - colum 2</h2>
<p>row 1 - colum 3</p>
<h2>row2 - colum 2</h2>
<p>row 2 - colum 3</p>
<h2>row3 - colum 2</h2>
<p>row 4 - colum 3</p>

Answer 1

You can fiddle with the loops a bit.
if ($row = $db->Row ())
{
echo '<h2>' ...;
do
{
echo '<h3>' ...;
echo '<p>' ...;
} while ($row = $db->Row ());
}

Make use a Sentinel value:
$i = 0;
while ($row = $db->Row()) {
echo "<h3>" . $row->titulo_video . "</h3>";
echo "<p>" . $row->subtitulo_video . "</p>";
if($i==0){
echo "<h3>" . $row->titulo_video . "</h3>";
echo "<p>" . $row->subtitulo_video . "</p>";
}
$i++;
}

If you really want to treat the first row differently, handle it entirely outside of the loop, rather than including a conditional in your while loop, it's cleaner to handle it like this:
$first_row = $db->Row();
echo "<h2>" . $first_row->nome_norma . "</h2>";
echo "<h3>" . $first_row->titulo_video . "</h3>";
echo "<h3>" . $first_row->subtitulo_video . "</h3>";
while ($row = $db->Row()) {
echo "<h3>" . $row->titulo_video . "</h3>";
echo "<p>" . $row->subtitulo_video . "</p>";
}
break;
