preg_replace and database

hi all, I have trouble with preg_replace and querying database, my code is below, <?php include("h/h.php"); function getImgAttributes($id){ $dsn = array( 'phptype' => "mysql",

	    'hostspec' => "localhost",
	    'database' => "db",
	    'username' => "root",
	    'password' => "pass"

); $myDbc = DB::connect($dsn); $myDbc->setFetchMode(DB_FETCHMODE_ASSOC); $select_sql="select width, height, name from files where id='$id'"; $execute_query = $myDbc->query($select_sql); $row=$execute_query->fetchRow(); return 'id="'.$id.'" width="'.$row['width'].'" height="'.$row['height'].'" alt="'.$row['name'].'"'; } function writeImgTag ($text){ $search = '<img id="(.*?)" />'; $replace = 'div class="cimg"><img src="thumb.php?w=200&q=60&id=\1" '.getImgAttributes("\\1").' /></div'; $text = preg_replace ($search, $replace, $text); echo $text; } $text='<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Donec fermentum aliquam dolor.</p> <img id="433" /> <p>Pellentesque convallis, felis vel imperdiet tincidunt, urna augue porttitor leo, eu luctus elit ante non mi.</p>'; writeImgTag($text); ?> returns id but not DB result.... <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Donec fermentum aliquam dolor.</p> <div class="cimg"><img src="thumb.php?w=200&q=60&id=433" id="433" width="" height="" alt="" /></div> <p>Pellentesque convallis, felis vel imperdiet tincidunt, urna augue porttitor leo, eu luctus elit ante non mi.</p>
