Question

I’m retreiving score & course_code from my table, so that all the courses that have a score less than 40 should be copied into an array $carry_over.

var_dump($carry_over) only gives "Array" when i run the script.  

Please how can i put/get the course_code of those courses that have a score of <40?
Thanks for the help. I most appreciate it.

    $carry_over = array(); 
          while ($row8 = mysql_fetch_assoc      ($query8)) {
 if ($row8['score'] < 40) {
$carry_over = array( 'm.course_code' =>      $row8['m.course_code']) ;
} 
}
var_dump($carry_over);  

Query8

        $query8 = mysql_query("SELECT  m.          score , m.course_code
    FROM    maintable AS m  
 INNER JOIN students AS s ON
 m.matric_no = s.matric_no
 INNER JOIN courses AS c ON
 m.course_code = c.course_code
 WHERE m.matric_no = '".$matric_no."'
 AND m.level = '".$level."'")
 or die (mysql_error());

Try below :

   $carry_over = array(); 
    while ($row8 = mysql_fetch_assoc($query8)) 
    {
      if ($row8['score'] < 40)
      {
        $carry_over[$row8['score']] = $row8['m.course_code']) ;
      } 
    }
    var_dump($carry_over);
