PHP Bir swf dosyası yüklemek ve dinamik olarak yükseklik ve genişliğini belirlemek için çalışıyorum SWF dosyasının

Question

boyutlarını olsun. PHP kullanan swf dosyasının boyutlarını okuyabilecek birileri var mı?

İşte ihtiyaç duyan herkes için çalışmış şey bu:

$aInfo = getimagesize($sFile); 
list($iWidth, $iHeight) = $aInfo; 

Answer 1

kullanım getimagesize

örnek:

php -r "print_r(getimagesize('http://adsatt.espn.go.com/ad/sponsors/ibm/Oct_2010/ibm0-728x90-0160.swf'));" 

 
Array 
(
    [0] => 728 
    [1] => 90 
    [2] => 13 
    [3] => width="728" height="90" 
    [mime] => application/x-shockwave-flash 
) 

PS: module gd is required

Answer 2

Veritabanında saklanan .SWF dosyalarında getimagesize() için bir çözüm arayanlar için, burada yazdığım bir stream_wrapper. PHP 5.3.10 üzerinde test edilmiştir.

     Code Summary 
     ======================================================================= 
     A simple class for PHP functions to read and write blob data as a file 
     using a stream wrapper. 

     Particularly useful for running getimagesize() to get the width and 
     height of .SWF Flash files that are stored in the database as blob data. 

     Requests for a simple way to get the width and height of .SWF blob data 
     in PHP have been around for years. So I decided to write and release 
     this code under the MIT license to save everyone some time, hopefully 
     this will also benefit people in other use cases. 

     Tested on PHP 5.3.10. 

     ======================================================================= 
     Usage Example 
     ======================================================================= 
       #Include 
         include('./blob_data_as_file_stream.php'); 

       #Register the stream wrapper 
         stream_wrapper_register("BlobDataAsFileStream", "blob_data_as_file_stream"); 

       #Fetch a .SWF file from the Adobe website and store it into a variable. 
       #Replace this with your own fetch-swf-blob-data-from-database code. 
         $swf_url = 'http://www.adobe.com/swf/software/flash/about/flashAbout_info_small.swf'; 
         $swf_blob_data = file_get_contents($swf_url); 

       #Store $swf_blob_data to the data stream 
         blob_data_as_file_stream::$blob_data_stream = $swf_blob_data; 

       #Run getimagesize() on the data stream 
         $swf_info = getimagesize('BlobDataAsFileStream://'); 
         var_dump($swf_info); 

     ======================================================================= 
     Usage Output 
     ======================================================================= 
       array(5) { 
        [0]=> 
        int(159) 
        [1]=> 
        int(91) 
        [2]=> 
        int(13) 
        [3]=> 
        string(23) "width="159" height="91"" 
        ["mime"]=> 
        string(29) "application/x-shockwave-flash" 
       } 

     ======================================================================= 
     Note for PHP version < 5.3.0 
     ======================================================================= 
     Replace all 'static::' with 'self::'
