PHP HTML 字符串转换为 CSV

发布于 2024-10-30 17:26:50 字数 779 浏览 0 评论 0原文

绕了一圈,希望有人能纠正我。

通过 PHP 生成 CSV 并使用 MySQL 中的数据。数据是由用户通过 TinyMCE 输入的,因此具有各种“p”标签等,我显然需要删除我可以成功完成的操作,但是即使在删除之后,csv 中的字符串仍然会显示在各种不同的单元格中。

我尝试过使用 strip_tags() 和 preg 匹配“/n”和“/r”以及各种方式来删除换行符,但没有运气,因为它仍然出现在新单元格上。

我在 csv 中使用分号作为分隔符。

我试图从中剥离所有 html 的字符串的示例是

我想加入,因为它看起来很有趣

 

< ;p>帮帮我。

。仅当它们有多个

标签或其他内容时才会发生这种情况 - 如果字符串只是一行,则不会出现任何问题。

这是我正在使用的 csv 代码:

    echo 'Username;Email;Date joined;Reason for joining'."\r\n";

    foreach($users as $user) {
        $csv_data .= $user->username . ';' . $user->email. ';' . date("d/m/y", $user->time_created) . ';' .  $user->reason_for_joining  .';'."\r\n";
    }

    echo $csv_data;

我哪里出错了?

谢谢大家:)

Going around in circles so hopefully someone can put me right.

Generating a CSV through PHP and using my data from MySQL. Data is inputted by the user via TinyMCE so has various "p" tags etc that I obviously need to strip out which I can do successfully, however the string in the csv still gets displayed in various different cells even after being stripped.

I've tried using strip_tags() and preg matching "/n" and "/r" and all sorts to remove line breaks but no luck as it still appears on new cells.

I'm using a semi colon as the seperator in the csv.

An example of a string i'm trying to strip all html from would be<p>I would like to join because it looks fun</p><p> </p><p>Help me.</p>. It only happens when their is more than one

tag or something - if the string is simply one line, it works no issues.

Heres the csv code i'm using:

    echo 'Username;Email;Date joined;Reason for joining'."\r\n";

    foreach($users as $user) {
        $csv_data .= $user->username . ';' . $user->email. ';' . date("d/m/y", $user->time_created) . ';' .  $user->reason_for_joining  .';'."\r\n";
    }

    echo $csv_data;

Where am i going wrong?

Thanks guys :)

CSV 格式的陷阱比人们想象的要多(正如您所经历的)。因此,不要重新发明轮子并使用 fputcsv,它正确地转义了所有需要转义的内容。

fputcsv 期望写入文件,但您可以给它一个假文件来写入,如 此处

$fp = fopen('php://output', 'w');

$delimiter = ';';
$headers = array('Username', 'Email', 'Date joined', 'Reason for joining');
fputcsv($fp, $headers, $delimiter);

foreach ($users as $user) {
    $fields = array($user->...);
    fputcsv($fp, $fields, $delimiter);
}

fclose($fp);

The CSV format has more pitfalls than one might imagine (as you are experiencing). Therefore, don't reinvent the wheel and use fputcsv, which correctly escapes everything that needs escaping.

fputcsv expects to write to a file, but you can give it a fake file to write to instead, as outlined here:

$fp = fopen('php://output', 'w');

$delimiter = ';';
$headers = array('Username', 'Email', 'Date joined', 'Reason for joining');
fputcsv($fp, $headers, $delimiter);

foreach ($users as $user) {
    $fields = array($user->...);
    fputcsv($fp, $fields, $delimiter);
}

fclose($fp);

你忘记了第一个回显的“\r”,
应该是:


echo 'Username;Email;Date joined;Reason for joining'."\r\n";

并且最好在“for”循环之前将 $csv_data 设置为空白。

如果“用户名”、“电子邮件”、“加入原因”中有分号,
该代码将生成格式错误的 csv。

you forgot the "\r" for the first echo,
supposed to be:


echo 'Username;Email;Date joined;Reason for joining'."\r\n";

and better set $csv_data to blank before the 'for' loop.

and if either 'username', 'email', 'reason_for_joining' has the semicolon,
the code will generate a mal-formed csv.
