PHP function problem

My PHP function for sidebar element generation looks like that

开发者_开发技巧

function makeSidebarEl ($side, $name, $lang, $db)
{
    $title='title_'.$lang;
    $txt='txt_'.$lang;
    $query=$db->query("SELECT $title, $txt FROM sidebar WHERE side='$side' AND name='$name'");
    $result=$query->fetch_array(MYSQLI_BOTH);
    $title=makeTitle($result[$title], $lang, $db);
    $txt=makeTxt($result[$txt], $lang, $db);
    echo '<div class="nav">'.$title.$txt.'</div>'."\n";
    }

But i'm getting result something like this

<div class="nav"></div>
<div class="nav_1"><img border="0" src=core/design/img/left_nav.png alt="" height="25px"/></div>
...

I mean it opens and closes <div class="nav"></div> at the begining of the every element but in fact function must echo result within this div:

echo '<div class="nav">'.$title.$text.'</div>'."\n"; How to fix that problem?

UPDATE

function makeTitle($title) {

    echo '<div class="nav_1"><img border="0" src=core/design/img/left_nav.png alt="" height="25px"/></div>
    <div class="nav_2">'.$title.'</div>
    <div class="nav_3"><img border="0" src=core/design/img/left_nav.png alt="" height="25px"/></div>
    <div style="clear:both;"></div>';

    }

function makeTxt($txt) {
    echo '<div id="parts" class="parts_txt">'.$txt.'</div>';
}

makeTitle() and makeText() should return strings rather than echo them.

As it is now, they echo text when they are called and return NULL, which is then concatenated into string when you call echo '<div class="nav">'.$title.$txt.'</div>'."\n";, i.e., that line evaluates to echo '<div class="nav">'.NULL.NULL.'</div>'."\n";

You need to replace echo to return at functions makeTitle and makeTxt
