推荐答案

您可以使用命令行工具(如Pdftotext)轻松读取PDF文件的内容，可以通过exec调用它.

You can easily read the contents of a PDF file using a command-line utility like Pdftotext which you can call through exec.

这是我的意思的示例，实际上是使用系统

This is an example of what i mean, actually using system

system("pdftotext your.pdf /tmp/txtfile.txt");
$text = file_get_contents("/tmp/txtfile.txt");

编辑

不知道破折号语法-甚至更好:

didn't know about the dash syntax - this is even better:

$content = shell_exec('pdftotext your.pdf -');

这确实需要在您的服务器上安装pdftotext.在CentOS服务器上，它将是:

This does require pdftotext to be installed on your server though. On a CentOS server this would be:

yum install xpdf
