php - 如何在单击时创建一个 php 变量 $_POST？

Question

我正在尝试使其$suggestion[$ss_count]成为一个可点击的链接，$_POST一旦点击它就会执行。我正在尝试实现查询扩展类的效果。这个词本身当然需要是发布的信息，它需要被识别为

if ($_POST['query'])     

我用于此的代码是：

<?php
if ($_POST['query'])

{
    $query = urlencode($_POST['query']);
    $s_count = 0;
    $ss_count = 0;
    $query = 'http://www.dictionaryapi.com/api/v1/references/collegiate/xml/'.$query.'?   key=135a6187-af83-4e85-85c1-1a28db11d5da';
    $xml = new SimpleXMLIterator(file_get_contents($query));
    foreach ($xml -> suggestion as $suggestion[$s_count])
    {
        $s_count++;
    }
    if ($s_count > 1)
    {
        echo ('<h4>Did you mean?</h4>');
        while ($ss_count <=$s_count)
        {
        echo ($suggestion[$ss_count].'<br>');
        $ss_count++;
        }

    }
}

?>
