PHP Laravel LibreOffice DOC 到 PDF 无法通过浏览器转换运行

Question

我目前正在通过 DropzoneJS 上传 DOC 或 DOCX 文件，然后使用 LibreOffice PHP exec 在服务器中将其转换为 PDF。如果我在服务器中手动输入它然后它会转换但是如果我运行它通过浏览器然后它不会转换。我正在尝试运行没有 sudo 的办公室，但是通过浏览器的命令运行不起作用。如何通过浏览器转换它运行?

终端中的手动命令：

/opt/libreoffice5.2/program/soffice --convert-to pdf /var/www/html/my_system/public/msword.doc --outdir /var/www/html/my_system/storage/app/quotations

命令 ls -liah 文件夹结果：

my_system、存储、应用程序、报价单 = drwxrwxrwx apache apache

我的 sudo visudo 结果（粘贴的行没有顺序注释）：

Defaults    requiretty
Defaults   !visiblepw
Defaults    always_set_home

www-data ALL=NOPASSWD:ALL
robert ALL=NOPASSWD:ALL
apache ALL=NOPASSWD:ALL

PHP 文件:

$command = '/opt/libreoffice5.2/program/soffice --convert-to pdf /var/www/html/my_system/public/msword.doc --outdir /var/www/html/my_system/storage/app/quotations';

if (!$return) {
    echo "PDF Created Successfully";
} else {
    echo 'PDF not created. Command = ' . $command . '=' . $return;
}

谢谢。

通过 https://superuser.com/questions/627266/convert-file-to-pdf-using-libreoffice-under-user-apache-i-e-when-using-php

找到了正确答案

引用正确答案：

So, you need to i) give apache's user a home and ii) give it a directory it has access to to write in. So, create a tmp directory in the same folder where you store your webpage and then run the following php code:

<?php
  shell_exec('export HOME=/tmp && libreoffice --headless -convert-to pdf --outdir ./tmp /tmp/ayb/document_34.doc');
?>

I just tested and it works perfectly on my machine. Make sure your ./tmp has its permissions set to 777. Also, you may need to restart apache if you play aroud with it too much. It stopped working for me after a while when I made changes and I needed to restart it.
