phpword错误地将base64图像导出到docx文件

// 获取base64图像数据
$base64Image = "data:image/png;base64,iVBORw0KG...";

// 将base64图像转换为二进制数据
$imageData = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $base64Image));

// 生成临时文件名
$tempFileName = tempnam(sys_get_temp_dir(), 'image');

// 将二进制数据保存为临时文件
file_put_contents($tempFileName, $imageData);

// 创建PHPWord实例
$phpWord = new \PhpOffice\PhpWord\PhpWord();

// 插入图片
$section = $phpWord->addSection();
$section->addImage($tempFileName);

// 保存为docx文件
$docxFileName = 'output.docx';
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007');
$objWriter->save($docxFileName);

// 删除临时文件
unlink($tempFileName);

// 返回生成的docx文件下载链接
$downloadLink = 'http://example.com/' . $docxFileName;
