The preview image of a PDF file is usually the first pageof the PDF file.
PDF 文件的预览图像通常是 PDF 文件的第一页。
You can use ImageMagickto obtain that first page of the PDF file.
您可以使用ImageMagick获取 PDF 文件的第一页。
<?php
$imagick = new imagick('sample.pdf[0]'); // 0 specifies the first page of the pdf
$imagick->setImageFormat('jpg'); // set the format of the output image
header('Content-Type: image/jpeg'); // set the header for the browser to understand
echo $imagick; // display the image
?>
You can also output (save the contents of the image in a file) and store it under a thumbnail folder with the PDF name as the file name. like ( sample.jpg )
您还可以输出（将图像内容保存在文件中）并将其存储在以 PDF 名称作为文件名的缩略图文件夹下。喜欢（样本.jpg）
As for a solution based on laravel, I don't think laravel has any package that can do the same
至于基于laravel的解决方案，我认为laravel没有任何可以做到这一点的包
