Question

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";
?>

我想将文件直接发送给用户下载而不保存到服务器。我真的并不是那么优秀的PHP，那么我需要添加/更改才能做到这一点？

Answer 1

header ("Content-Type: application/octet-stream");
header ("Content-disposition: attachment; filename=S3S.cfg");
echo $string; //the string that is the file

Answer 2

继续你应该怎么做，你的html标签应该是小写的＆amp;除非你输出一个值表，否则不要使用表格，使用带有css的div。您还可以回发到脚本，因为从表单收到的变量是特定的，您只需检查正确的值，然后将数据发送回用户。

<?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;
}
?>
