PHP：下载PDF文件，而无需直接链接

Question

我想从这个网址下载PDF文件：

http://knihy.cpress.cz/?p=actions&action=download/file&value=files&id=149253 

我试图获取文件的file_get_contents通过，但它只是下载的PHP文件没有实际的PDF文件。

有没有办法可以下载这个文件？

非常感谢！

<?php 

    function collect_file($url){ 
     $ch = curl_init(); 
     curl_setopt($ch, CURLOPT_URL, $url); 
     curl_setopt($ch, CURLOPT_VERBOSE, 1); 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
     curl_setopt($ch, CURLOPT_AUTOREFERER, false); 
     curl_setopt($ch, CURLOPT_REFERER, "http://www.xcontest.org"); 
     curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); 
     curl_setopt($ch, CURLOPT_HEADER, 0); 
     $result = curl_exec($ch); 
     curl_close($ch); 
     return($result); 
    } 

    function write_to_file($text,$new_filename){ 
     $fp = fopen($new_filename, 'w'); 
     fwrite($fp, $text); 
     fclose($fp); 
    } 


    // start loop here 

    $new_file_name = "testfile.pdf"; 
    $url = "http://knihy.cpress.cz/?p=actions&action=download/file&value=files&id=149253"; 

    $temp_file_contents = collect_file($url); 
    write_to_file($temp_file_contents,$new_file_name) 

    // end loop here 
?> 

from here
