在输出中获取php作为文本 [英] getting php as text on output

问题描述

首先，这是我的PHP代码。我试图将此代码作为文本输出。不知道我该怎么做。使用html，我们可以做到 \将其插入到PHP中，但是如何在代码中完成这样的操作？

 <？php 
 $ stringData =
 
 //从这里开始
 
<？php 
 $ width = $ _GET ['width']; 
 $ heigh = $ _GET ['height']; 
 
 echo'你好'; 
 
？> 
 //到此为止
 
; 
？> 
  

我已经标记了那部分，我希望将它作为文本输出，但是当我在页面上放置它时，我得到的语法错误不确定原因。

编辑＃2

下面是我的完整代码，我解释了我的代码是如何工作的以及为什么。
我的代码是创建页面并将内容放入创建页面

 < form method =post> 
< label>页面名称：< / label>< br> 
< input>'text'name ='filename'placeholder ='page name'> 
< label>文件夹< / label> 
< ;选择name =thisfolder> 
< / option> 
< / option> 
< / option> 
< option value =>默认< < option value =Folder2> Folder2< / option> 
< option value =Folder3> Folder3< / option> 
< / gt>< br>< br> ; 
 <标签>&内容LT; /标签><峰; br> 
< input type ='text'name ='strin'placeholder ='创建页面的内容'> 
< input type ='submit'value ='Add Feed'> 
< / form> 
 
 <？php 
 if（$ _SERVER [REQUEST_METHOD] ==POST）
 {
 //要创建的文件的名称
 $ filename = $ _ POST ['filename']; 
 //创建页面的文件的名称
 $ strin = $ _ POST ['strin']; 
 //将$ filename放入
 $文件夹的名称thisFolder = $ _POST ['thisfolder']; 
 //确保#thisFolder实际上是一个文件夹
 if（！is_dir（__ DIR __。'/'。$ thisFolder））{
 //如果不是，我们需要创建一个新文件夹
 mkdir（__ DIR __。'/'。$ thisFolder）; 
} 
 //。 。 。 / [文件夹名称] /页面[文件名称] .php 
 $ myFile = __DIR __。'/'。$ thisFolder。 / page。$ filename。。php; 
 $ fh = fopen（$ myFile，'w'）; 
 $ stringData =
 
<？php 
 $ width = $ _GET ['width']; 
 $ heigh = $ _GET ['height']; 
 
 echo''; 
 
？> 
 
; 
 
 fwrite（$ fh，$ stringData）; 
 fclose（$ fh）; 
} 
？> 
  

我想要做的是，传递位于 $ stringData 到将要创建的页面

解决方案

您需要转义 $ 在您的文本中。

设置 $ stringData 这：

  $ stringData =
 
 //从这里开始
 
 <？php 
 \ $ width = \ $ _GET ['width']; 
 \ $ heigh = \ $ _GET ['height']; 
 
 echo'Hello'; 
 
？> 
 //在此结束
 
; 
  

first of all this is my php code. i am trying to get this code as text on output. not sure how i do that. with html we can do \" to insert it inside php but how do i get this done like that on my code ?

<?php
$stringData = "

    // Start here

    <?php
    $width = $_GET['width'];
    $heigh = $_GET['height'];

        echo 'Hello';

    ?>
    // End here

    ";
?>

i have marked that part that i want to get it on output as text but when i put it like that on page i get syntax error not sure why.

EDIT #2

here below is my full code and i explain how my code works and for what. my code is to create page and put something inside that page created

<form method="post">
    <label>Page Name:</label><br>
    <input type='text' name='filename' placeholder='page name'>
    <label>Folders</label>
    <select name="thisfolder">
        <option value="">Default</option>
        <option value="Folder1">Folder1</option>
        <option value="Folder2">Folder2</option>
        <option value="Folder3">Folder3</option>
    </select><br><br>
    <label>content</label><br>
    <input type='text' name='strin' placeholder='content of created page'>
    <input type='submit' value='Add Feed'>
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
    // the name of the file to create
    $filename=$_POST['filename'];
    // the name of the file to be in page created
    $strin=$_POST['strin'];
    // the name of the folder to put $filename in
    $thisFolder = $_POST['thisfolder'];
    // make sure #thisFolder of actually a folder
    if (!is_dir(__DIR__.'/'.$thisFolder)) {
        // if not, we need to make a new folder
        mkdir(__DIR__.'/'.$thisFolder);
    }
    // . . . /[folder name]/page[file name].php
    $myFile = __DIR__.'/'.$thisFolder. "/page" .$filename.".php";
    $fh = fopen($myFile, 'w');
    $stringData = "

    <?php
    $width = $_GET['width'];
    $heigh = $_GET['height'];

        echo '';

    ?>

    ";

    fwrite($fh, $stringData);
    fclose($fh);
}
?>

what i am trying to do is, passing that php code that is inside $stringData to that page that will be created

解决方案

You'll want to escape the $'s in your text.

Set $stringData like this:

$stringData = "

// Start here

<?php
\$width = \$_GET['width'];
\$heigh = \$_GET['height'];

    echo 'Hello';

?>
// End here

";
