Question

我正在构建一个在我的localhost上运行的工具，它有助于将静态网页放在一起更快一些。安全性不是问题，因为这只是在本地运行。

首先，我有一个名为include的{{1}}文件，其中包含如下页面部分的变量：

components.php

然后我的网址看起来像这样：

$slide="Pretend this is markup for a Slider";
$port="Pretend this is markup for a set of portfolio images";
$para="<p>Just another paragraph</p>";
$h1="<h1>This is a Header</h1>";

我的索引文件包含：

//only calling 3 of the 4 sections
localhost/mysite/index.php?sections=h1-slide-para

这里的目标是使用我一直使用的行构建include 'components.php' $sections = @$_GET['sections']; $section = explode($sections,"-"); foreach ($section as $row){ echo $row; }文件，这样我就可以从浏览器的地址栏快速将页面布局放在一起。我只是不确定如何components.php变量echo，explode只包含我从index.php文件调用的标记。

Answer 1

这应该适合你：

只需使用variable variables访问components.php文件中的变量（同时切换explode()中的参数，它们是错误的方法），例如

$section = explode("-", $sections);

foreach ($section as $row) {
    echo $$row;
       //^^ See here the double dollar sign
}

另一种解决方案是将文件更改为ini格式，例如

slide="Pretend this is markup for a Slider"
port="Pretend this is markup for a set of portfolio images"
para="<p>Just another paragraph</p>"
h1="<h1>This is a Header</h1>"

然后将其放入包含parse_ini_file()的数组：

$arr = parse_ini_file("components.ini");
                                //^^^ Note, that you now work with an .ini file    

$sections =  @$_GET['sections'];
$section = explode("-", $sections);
foreach ($section as $row) {
    echo $arr[$row];
}

Answer 2

将字符串放入数组：

$sections = [
    'slide' => "Pretend this is markup for a Slider",
    'port' => "Pretend this is markup for a set of portfolio images",
    'para' => "<p>Just another paragraph</p>",
    'h1' => "<h1>This is a Header</h1>",
];

然后，按名称引用这些部分：

foreach (explode('-', $_GET['sections']) as $section){
    echo $sections[$section];
}

Answer 3

首先代替

<select style="width: 100%"></select>

使用

$section = explode($sections, "-");

以及

$section = explode("-", $sections);

PHP解析变量的url
