PHP - 从链接下载pdf文件并保存在本地文件夹中

I am trying to get through an API, a live open access pdf file, and then download that file to my server. However the PDF file does not end with a ".pdf" extension but is encapsulated in a more complexe url: http://aip.scitation.org/doi/pdf/10.1063/1.4996175 A web browser would simply ask to open or save it as a PDF file, whereas my script cannot translate it as such. How can I make my PHP script recognize this url as a PDF file? Thanks in advance. Olivier

    It is not clear what exactly you are doing and why your php script has to recognize pdf.

    If you are loading the file by your php application - you can check content type header of the file, which contains file type information along with the extension. You can use http://php.net/manual/en/book.curl.php library for it.

    If you want to let users download the file on your site - you have to set correct content type like this:

    header('Content-Type: application/pdf');
    

    Now the browser will know that the file you are serving is pdf even without extension.

    Update

    Eventually it turned out that the site with pdf files just required some cookies, as described below.
