Hey Guys I have a problem I am trying to fetch area to my table but is is displaying just one row even if I have 4 with condition that I set

What I have tried:

here is my mysql

 <?php
$findmessage = mysqli_query($dbc, "SELECT * FROM privatemessages WHERE to_id= '$username'");
if($res = mysqli_fetch_array($findmessage))
{
$msgid = $res['id']; 
$from = $res['from_id']; 
$subject = $res['subject'];   
$senton = $res['time_sent'];  
$read = $res['opened']; 
}
?>

here is my table

<table cellpadding="0" cellspacing="0" border="0">
      <thead>
        <tr>
          <th>FROM:</th>
		     
          <th>Subject</th>
          <th>Sent on</th>
          <th>Read</th>
         
        </tr>
      </thead>
	<?php 
 

    	
		echo "<tr>";
		echo "<td>".$from."</td>";
  	echo "<td>".$subject."</td>";
		echo "<td>".$senton."</td>";
    echo "<td>".$read."</td>";	
    echo "<tr>";
        
	
	?>
	</table>

I even tried like this

<?php


while($res = mysqli_fetch_array($findmessage)) {
    echo "<tr>";
    echo "<td>".$res['from_id']."</td>";
    echo "<td>".$res['subject']."</td>";
    echo "<td>".$res['time_sent']."</td>";
echo "<td>".$res['opened']."</td>";
echo "<td>";

}
?>

Never concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Always use Parameterized queries instead.

When you concatenate strings, you cause problems because SQL receives commands like:

SQL

SELECT * FROM MyTable WHERE StreetAddress = 'Baker's Wood'

The quote the user added terminates the string as far as SQL is concerned and you get problems. But it could be worse. If I come along and type this instead: "x';DROP TABLE MyTable;--" Then SQL receives a very different command:

SQL

SELECT * FROM MyTable WHERE StreetAddress = 'x';DROP TABLE MyTable;--'

Which SQL sees as three separate commands:

SQL

SELECT * FROM MyTable WHERE StreetAddress = 'x';

A perfectly valid SELECT

SQL

DROP TABLE MyTable;

A perfectly valid "delete the table" command

SQL

--'

And everything else is a comment.
So it does: selects any matching rows, deletes the table from the DB, and ignores anything else.

So ALWAYS use parameterized queries! Or be prepared to restore your DB from backup frequently. You do take backups regularly, don't you?
