prodigitalson，我想为您发布此解决方案，以防您仍然对想要找到答案感到好奇。它仅适用于针对 1.5 版 (Acrobat 6.0) 优化的 PDF，但它确实运行良好。它是 Zend Framework 1.12.3 的一个非官方补丁，用于填充 PDF 表单字段。 Site with the discussion and patch
无需安装，无需外部程序，无需坐标
首先使用以下内容更新您的 php.ini 文件（注意：当我上传这些更改时，我必须在我的实际 Web 服务器上更改我的 .ini 文件）：
include_path = ".;C:\wamp\www\includes"
请注意：我将所有库内容从 'ZendFramework-1.12.3\library' 文件夹中移出到名为 Zend:C:\wamp\www\includes\Zend 的文件夹中，只是为了方便引用库（这就是您所需要的一切） )。
然后在您的 php 文件中（我使用了“DIRECTORY_SEPARATOR”，以便您可以在 Win 或 Unix 服务器上使用它，并且我不必根据我的 .php 文件的位置进行任何代码更改，我会只需更改服务器配置）：
require_once('Zend'.DIRECTORY_SEPARATOR.'Loader'.DIRECTORY_SEPARATOR.'Autoloader.php');
$loader = Zend_Loader_Autoloader::getInstance();
$loader->registerNamespace('Zend_');
然后进行实际代码使用：
$pdf = Zend_Pdf::load('input-file-containing-form.pdf');
$pdf->setTextField('name', 'Someone');
$pdf->setTextField('address', '1 Main Street');
$pdf->setTextField('city', 'Cyberspace');
$pdf->save('outputfile.pdf');
或者因为我这样做是为了我的目的（我还包括我用来通过电子邮件发送我完成的就业申请然后删除 .pdf 文件以便它不会阻塞我的服务器的代码：attach_mailer_class.php available here版权所有 (c) 2006，Olaf Lederer)：
// Write $_POST form data to associative array
foreach ($_POST as $key => $value) {
$NameArray[$key] = $value;
}
// Path to PDF application fillable file
$pdf_path = dirname(__FILE__) . "\\docs";
$pdf_filename = 'employment_applicationJBzend.pdf';
$pdf_file_path = $pdf_path . "\\" . $pdf_filename;
// Path to PDF application file save location
$result_path = dirname(__FILE__) . "\\results";
$result_filename = ucfirst($_POST['first_name']) . ucfirst($_POST['last_name']) . $filedatetime . '.pdf';
$result_file_path = $result_path . "\\" . $result_filename;
//Filling PDF fields | Example: $pdf->setTextField('position_applied_for', 'IT Manager');
$pdf = Zend_Pdf::load($pdf_file_path);
foreach ($NameArray as $key1 => $value) {
foreach($ExceptionArray as $key2 => $value)
{
if($key1 == $ExceptionArray[$key2]){
$boolSetText = false;
break;
}else{
$boolSetText = true;
}
}
if($boolSetText){
$pdf->setTextField($key1, $NameArray[$key1]);
}
}
$pdf->save($result_file_path);
//Create and send message using 'attach_mailer_class.php
$email = new attach_mailer($from_name, $from_mail, $mail_to, $cc = "", $bcc = "", $subject);
$email->text_body = $message;
$email->add_attach_file($result_file_path);
// $email->add_attach_file("ip2nation.zip");
$email->process_mail();
unlink($result_file_path);
如果页面不再存在这里是 PDF.php 的补丁（如果你不知道如何运行实际的补丁，基本上你会检查你的 PDF.php 文件并替换下面的所有行'+' 在它们前面。您可以通过位置标签 '@@ -202,6 +202,13 @@' 找到它们的位置，它位于第 200 行附近，然后只需复制并粘贴以将旧代码替换为新）：
