PHP only show text once in loop

我有一个网页，这是从字符串$details抓取信息，并通过搜索和显示结果寻找'displayname'。这是LDAP Active Directory查询。

我需要"$search .= "NameTitlePhoneMobileEmailDept'n";"只显示一次搜索已完成。在当前状态下，它对每个结果重复这一行。我怎样才能让这条线只显示一次呢?

    // Address Book Search
    $search .= "<div class='border'>'n";
    $search .= '<form class="search-form-wrapper" method="GET">
                    <input type="text" name="q" id="search" placeholder="Search for Staff..." required>
                    <input type="submit" value="go" id="submit">
                </form><br><br>';

    if (count($staff)) {
    if (isset($_GET['q'])) {
        $query = rawurlencode( strip_tags($_GET['q']));
        $query = ucfirst($query);
        foreach ($staff as $key => $details) {
            if(substr_count($details['displayname'], $query)){
            $search .= "<table class='address_book'><tr><th>Name</th><th>Title</th><th>Phone</th><th>Mobile</th><th>Email</th><th>Dept</th></tr>'n";
            $search .= "<tr><td>{$details['displayname']}</td>'n";
            $search .= "<td>{$details['title']}</td>'n";
            $search .= "<td>{$details['telephonenumber']}</td>'n";
            $search .= "<td>{$details['mobile']}</td>'n";
            $search .= "<td><a href='mailto:{$details['mail']}'>{$details['mail']}</a></td>'n";
            $search .= "<td>{$details['department']}</td>'n";
            $search .= "</tr>'n";
            $search .= "</table>'n";
            }
        }       
    }
    }
    $search .= "</div><br>";
$layout->content($search);

要获得所需的功能性，可能必须将行:$search .= "<table class='address_book'><tr><th>Name</th><th>Title</th><th>Phone</th><th>Mobile</th><th>Email</th><th>Dept</th></tr>'n"移出循环(就在循环开始之前)。您只在循环中生成表的动态行。下面的代码片段说明了如何做到这一点:

   <?php
        // Address Book Search
        $search  = "";
        $search .= "<div class='border'>'n";
        $search .= '<form class="search-form-wrapper" method="GET">
                        <input type="text" name="q" id="search" placeholder="Search for Staff..." required>
                        <input type="submit" value="go" id="submit">
                    </form><br><br>';

        if (count($staff)) {
            if (isset($_GET['q'])) {
                $search .= "<table class='address_book'><tr><th>Name</th><th>Title</th><th>Phone</th><th>Mobile</th><th>Email</th><th>Dept</th></tr>'n";
                $query   = rawurlencode( strip_tags($_GET['q']));
                $query   = ucfirst($query);
                foreach ($staff as $key => $details) {
                    if(substr_count($details['displayname'], $query)){
                        $search .= "<tr><td>{$details['displayname']}</td>'n";
                        $search .= "<td>{$details['title']}</td>'n";
                        $search .= "<td>{$details['telephonenumber']}</td>'n";
                        $search .= "<td>{$details['mobile']}</td>'n";
                        $search .= "<td><a href='mailto:{$details['mail']}'>{$details['mail']}</a></td>'n";
                        $search .= "<td>{$details['department']}</td>'n";
                        $search .= "</tr>'n";
                    }
                }
                $search .= "</table>'n";
            }   
        }
        $search .= "</div><br>";
        $layout->content($search);
