Re: Usiing FOREACH to loop through Array

Oops! It's hot, it's Saturday, brain not functioning at 100%, made cut'n'paste error: <SNIP> or (2) set a flag in getCourses() so that the query is only executed once, otherwise returning a result line - something like: function getCourses($UID)

    global $link;
    static $result = false;

    if (!$result)
     {
       $result = mysql_query( "SELECT C.CourseName FROM tblcourses C, tblusers U,
        tblEnrollment E WHERE C.ID = E.CourseID AND E.UserID = U.ID AND U.ID =
        $UID", $link );
       if ( ! $result )
        die ( "getRow fatal error: ".mysql_error() );
     }
    {
    return mysql_fetch_array( $result );
    }

... while ($Row = getCourses($session[id]) as $value)

    {
    print "<br>", $Row['C.CourseName'];
    }

<SNIP> This last block of code should be while ($Row = getCourses($session[id]))

    {
    print "<br>", $Row['C.CourseName'];
    }
