Question

我正在尝试以特定格式将数据存储在文本文件中。

以下是代码：

<?php
header ('Location: http://myshoppingsite.com/ ');
$handle = fopen("userswhobought.txt", "a");
foreach($_POST as $variable => $value) {
    fwrite($handle, $variable);
    fwrite($handle, "=");
    fwrite($handle, $value);
    fwrite($handle, "\r\n");
}
fwrite($handle, "===============\r\n");
fclose($handle);
exit;
?>

所以在之前的HTML页面上，他们输入了2个值，它们的名称和位置，然后上面的php代码会告诉我他们输入的信息，并将它存储在userswhobought.txt中

这就是它目前的存储方式：

Username=John
Location=UK
commit=
===============

但我只想让它像这样存储

John:UK
===============
Nextuser:USA
==============
Lee:Ukraine

所以我更容易提取。

Answer 1

<?php
    header ('Location: http://myshoppingsite.com/ ');
    $handle = fopen("userswhobought.txt", "a");
    fwrite($handle, $_POST['Username']);
    fwrite($handle, ":");
    fwrite($handle, $_POST['Location']);
    fwrite($handle, "===============\r\n");
    fclose($handle);
    exit;
?>

Answer 2

<?php
header ('Location: http://myshoppingsite.com/ ');
$handle = fopen("userswhobought.txt", "a");
foreach($_POST as $variable => $value) {
fwrite($handle, $variable);
fwrite($handle, ":");
fwrite($handle, $value);
fwrite($handle, "===============\r\n");
}

fclose($handle);
exit;
?>

Answer 3

foreach($_POST as $variable => $value) {
    $write_this = "$variable:$value\r\n"
    fwrite($handle, $write_this );
}
fwrite($handle, "===============\r\n");

另外，我建议在退出之前将header（）调用移到右边。从技术上讲，这是有效的，但并不是大多数人所做的。

Answer 4

只需在您的文件中添加$_POST['Username'].":".$_POST['Location']."\r\n"，而不是您的foreach。

Answer 5

只需将fwrite($handle, "===============\r\n");放入循环中即可。

Answer 6

拿原始代码

<?php
header ('Location: http://myshoppingsite.com/ ');
$handle = fopen("userswhobought.txt", "a");
foreach($_POST as $variable => $value) {
    fwrite($handle, $variable);
    fwrite($handle, "=");
    fwrite($handle, $value);
    fwrite($handle, "\r\n");
}
fwrite($handle, "===============\r\n");
fclose($handle);
exit;
?>

并改为

<?php
$datastring = $_POST['Username'].":".$_POST['Location']."
===============\r\n";
file_put_contents("userswhobought.txt",$datastring,FILE_APPEND);
header ('Location: http://myshoppingsite.com/ ');
exit;
?>

您需要直接操作POST数据，而不是循环遍历$_POST数据，然后您可以随意使用它，但我建议您查看mysql，postgres或sqlite等数据库选项 - 您可以甚至将数据存储在像mongodb这样的nosql选项中。

以某种格式存储变量PHP
