创建要下载的文件而不用PHP保存在服务器上 [英] Create file for download without saving on server with PHP
本文介绍了创建要下载的文件而不用PHP保存在服务器上的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
说我的PHP代码是
<?php
// Get form variables using POST method
$MarriagePostMortem=stripslashes($_POST['MarriagePostMortem']);
$AutoSavesToKeep=stripslashes($_POST['AutoSavesToKeep']);
// Open and write file
$myFile="S3S.cfg";
$fh = fopen($myFile, 'w+') or die("can't open file");
fwrite($fh, "The Sims 3 Starter Configuration
-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
MarriagePostMortem $MarriagePostMortem
AutoSavesToKeep $AutoSavesToKeep
-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-");
fclose($fh);
//echo "file written\n";
?>
我想直接将文件发送给用户以下载而不保存到服务器。我真的对PHP并不是很好，所以我到底需要添加/更改什么呢？
I want to send the file directly to the user for download without saving it to the server. I'm really not all that great with PHP, so what exactly would I need to add/change to do so?
推荐答案
在此应如何操作，您的html标记应为小写& ;；除非您输出值表，否则请不要使用表，将div与CSS配合使用。您还可以发回脚本，因为从表单接收的变量是特定的，您只需要检查正确的值，然后将数据发送回用户即可。
Heres how you should do it, your html tags should be lower case & stay clear of tables unless your outputting a table of values, use divs with css. You can also post back to the script, as variables received from the form are specific you just check there the right value and then send the data back to the user.
<?php
if($_SERVER['REQUEST_METHOD']=='POST'){
$mpm = (!empty($_POST['mpm']) && ($_POST['mpm']=='true' || $_POST['mpm']=='false'))?$_POST['mpm']:die('Wrong parameter type');
$astk = (!empty($_POST['astk']) && is_numeric($_POST['astk']))?$_POST['astk']:die('Wrong parameter type');
$content = "The Sims 3 Starter Configuration".PHP_EOL;
$content .= "-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-".PHP_EOL;
$content .= "MarriagePostMortem $mpm".PHP_EOL;
$content .= "AutoSavesToKeep $astk".PHP_EOL;
$content .= "-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-".PHP_EOL;
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-disposition: attachment; filename=S3S.cfg');
header('Content-Length: '.strlen($content));
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Expires: 0');
header('Pragma: public');
echo $content;
exit;
}
?>
