Question

我的网站上有php，可以为多个网站创建搜索框。我只是设置了vhosts（子域）并将搜索目录移动到它。在这之后，php现在显示在页面上，以及成功执行。我不知道它是如何做到的，但确实如此。代码全部如下：

<html>
<body>

<?php
if (isset($_GET['q'])){
 $query = $_GET['q'];
 echo "<meta http-equiv=\"refresh\" content=\"0;URL=http://www.google.co.uk/search?q=$query\">";
}

if (isset($_GET['p'])) {
 $yquery = $_GET['p'];
 echo "<meta http-equiv=\"refresh\" content=\"0;URL=http://uk.search.yahoo.com/search?p=$yquery\">";
}

if (isset($_GET['yt'])) {
 $ytquery = $_GET['yt'];
 echo "<meta http-equiv=\"refresh\" content=\"0;URL=http://www.youtube.com/results?search_query=$ytquery\">";

}

if (isset($_GET['amz'])) {
 $amzquery = $_GET['amz'];
 echo "<meta http-equiv=\"refresh\" content=\"0;URL=http://www.amazon.co.uk/s/keywords=$amzquery\">";

}

if (isset($_GET['eby'])) {
 $ebyquery = $_GET['eby'];
 echo "<meta http-equiv=\"refresh\" content=\"0;URL=http://www.amazon.co.uk/sch/i.html/_nkw=$ebyquery\">";

}
?>


<div id="searchForms">
<form id="gSearch" method="GET" action="http://www.google.co.uk/search"  />
<input type="text" name="q" placeholder="Google UK" value='' />
<input type="submit" value="Google Search"/>
</form>

<form id="ySearch" method="GET" action="http://uk.search.yahoo.com/search" />
<input type="text" name="p" placeholder="Yahoo" value='' />
<input type="submit" value="Yahoo Search"/>
</form>

<form id="ytSearch" method="GET" action="http://www.youtube.com/results" />
<input type="text" name="search_query" placeholder="YouTube" value='' />
<input type="submit" value="YouTube Search"/>
</form>

<form id="ebySearch" method="GET" action="http://www.EBay.co.uk/sch/i.html" />
<input type="text" name="_nkw" placeholder="EBay" value='' />
<input type="submit" value="EBay Search"/>
</form>

<form id="amzSearch" method="GET" action="http://www.amazon.co.uk/s/" />

Answer 1

这不是您搜索的内容，但最好使用

header('Location: http://www.google.co.uk/search?q='.quotemeta($query));

和切换/案例......

非常重要的是，检查您对安全模式的输入。 The Open Web Application Security Project

Answer 2

PHP不是nescassery，实际上对搜索框没有任何作用。可以并且应该删除<?php和?>之间的所有内容，因为表单的action属性已经在进行重定向。

PHP执行AND显示为文本
