推荐答案

您可以使用Linux上Xpdf软件包随附的pdftotext之类的东西.然后可以使用popen命令将pdftotext的输出通过管道传递给字符串:

You could use something like pdftotext which comes with the Xpdf package on linux. The popen command can then be used to pipe the output of pdftotext into a string:

$mystring = "";
$fd = popen("/usr/bin/pdftotext blah.pdf","r");
if ($fd) {
    while (($myline = fgets($fd)) !== false) {
        $mystring .= $myline;
    }
}
