[英]How could I display the source file.php in HTML?
我有以下PHP腳本(file.php),它顯示當前時間並顯示用戶的輸入:
Current time:
<?php
$time=time();
$actual_time=date('H:i:s',$time);
echo $actual_time;
//show user input
$enter=@$_POST['enter'];
echo '<br>Input: '.$enter;
?>
<form action="" method="POST">
<input type="text" name="enter">
<input type="submit" value="Refresh">
</form>
如果我輸入例如<strong>test</strong>
,我會看到:
如果我輸入<iframe src="file.php"></iframe>
,我可以在較小的窗口中重新加載頁面:
那么,現在,如何通過在INPUT文本字段中提交某些HTML代碼來顯示原始PHP腳本(file.php)?
<?php
// Disable a WebKit security feature
// which would prevent from showing the source code.
header('X-XSS-Protection: 0');
if (isset($_GET['source']) || isset($_POST['source'])) {
$source = file_get_contents(__FILE__);
// To prevent this control from showing up
// in the output source code
// enable the code below.
/*
$lines_to_remove = 26;
$source = explode("\n", $source, $lines_to_remove);
$source = $source[$lines_to_remove - 1];
*/
$source = highlight_string($source, true);
echo $source;
return;
}
?>
Current time:
<?php
$time=time();
$actual_time=date('H:i:s',$time);
echo $actual_time;
//show user input
$enter=@$_POST['enter'];
echo '<br>Input: '.$enter;
?>
<form action="" method="POST">
<input type="text" name="enter">
<input type="submit" value="Refresh">
</form>
htmlspecialchars — Convert special characters to HTML entities
$new = htmlspecialchars("<a href='test'>Test</a>", ENT_QUOTES);
echo $new;
//This would be the output
<a href='test'>Test</a>
//browser will display
<a href='test'>Test</a>
htmlentities -Convert all applicable characters to HTML entities
$str = "A 'quote' is <b>bold</b>";
echo htmlentities($str);
// Outputs: A 'quote' is <b>bold</b>
echo htmlentities($str, ENT_QUOTES);
// Outputs: A 'quote' is <b>bold</b>
In browser it woulbe displayed:
A 'quote' is <b>bold</b>
將輸入解析為純文本應顯示文件:
<?php
$time=time();
$actual_time=date('H:i:s',$time);
echo $actual_time;
//show user input
$enter=@$_POST['enter'];
header("Content-Type: text/plain");
echo '<br>Input: '.$enter;
?>
當然,您必須自定義腳本以檢測用戶何時想要顯示文件,然后才更改內容類型(否則其他html輸入將不起作用)。
提交html或php代碼然后顯示:
<?php
$time=time();
$actual_time=date('H:i:s',$time);
echo $actual_time;
//show user input
$enter=@$_POST['enter'];
echo '<br>Input: <pre>'.htmlspecialchars($enter).'</pre>';
?>
<form action="test.php" method="POST">
<input type="text" name="enter">
<input type="submit" value="Refresh">
</form>
打開文件然后顯示:
<?php
$myfile = fopen("test.php", "r") or die("Unable to open file!");
echo '<pre>'.htmlspecialchars(fread($myfile,filesize("test.php"))).'</pre>';
fclose($myfile);
?>
文件名:test1.php
在此文件中寫下以下代碼:
<?php
$time=time();
$actual_time=date('H:i:s',$time): ;
echo $actual_time;
$enter=@$_POST['enter'];
if (isset($enter)) {
$doc = new DOMDocument();
@$doc->loadHTML($enter);
$tags = $doc->getElementsByTagName('iframe');
foreach ($tags as $tag) {
$file_name = $tag->getAttribute('src');
}
if(isset($file_name)){
$result ='<iframe src='.$file_name.'></iframe>';
}else{
$result = $enter;
}
}
echo '<br>Input: '.$result;
?>
<form action="" method="POST">
<input type="text" name="enter">
<input type="submit" value="Refresh">
</form>
創建一個新文件:test6.php
在此文件中寫下面的代碼:
<?php
$myfile = fopen("test1.php", "r") or die("Unable to open file!");
echo '<pre>'.htmlspecialchars(fread($myfile,filesize("test1.php"))).'</pre>';
fclose($myfile);
?>
命中文件:test1.php
寫入輸入標記: <iframe src="test6.php"></iframe>
它會工作!!
我不完全理解你想要實現的目標,但是,我認為highlight_file()
函數應該有所幫助。
echo highlight_file('file.php',true);
