Aspose.PDF - 设置 PDF 过期

要使用 Aspose.PDF Java for PHP 为 PDF 文档设置过期，简单地调用 SetExpiration 类。

PHP 代码

# Open a pdf document.
$doc = new Document($dataDir . "input1.pdf");

$javascript = new JavascriptAction(
        "var year=2014;
    var month=4;
    today = new Date();
    today = new Date(today.getFullYear(), today.getMonth());
    expiry = new Date(year, month);
    if (today.getTime() > expiry.getTime())
    app.alert('The file is expired. You need a new one.');");
$doc->setOpenAction($javascript);

# save update document with new information
$doc->save($dataDir . "set_expiration.pdf");

print "Update document information, please check output file." . PHP_EOL;
