使内部回声功能在格式化位置输出

Question

I have tried many approaches to get this right, including all types of quoting, etc. I will give you my current code before explaining the situation.

function show_msgs($msgs)
{
    foreach($msgs as $msg) {
        echo '<div class="msg">' . $msg . '</div>' . "
    ";
    }
}

function generate_msgBox()
{
    global $array;        

    $stackoverflow = 
<<<EOT
    <div class="container">
        <div class="msgBox">
            %s      
        </div>
    </div>
EOT;

    $stackoverflow = sprintf($stackoverflow, show_msgs($array));

    echo $stackoverflow;
}

generate_msgBox function currently outputs this when called:

<div class="msg">First message!</div>
    <div class="msg">Seconds message!</div>

    <div class="container">
        <div class="alertBox">

        </div>
    </div>

However I need it to output this:

<div class="container">
    <div class="alertBox">
        <div class="msg">First message!</div>
        <div class="msg">Seconds message!</div>       
    </div>
</div>

I tried putting function directly inside echo that is enclosed by normal quotes and I got the same result.

How do I fix this?

Echo in show_msgs function works before output of generate_msgBox function - when you call it. just return string with result of function

function show_msgs($msgs)
{
    $ret = '';
    foreach($msgs as $msg) {
        $ret .= '<div class="msg">' . $msg . '</div>' . "
    ";
    }
    return $ret;
}
