Determine ActionScript version of swf using PHP on Linux webserver

Determine ActionScript version of swf file using PHP. Below is a link to some code in C# that maight be helpful. To clarify, I'm running webserver that has PHP on it and a lot of SWF files. I need a function in PHP that will determine Actionscript version of any particular SWF file. The server uses Linux as an OS. Need to be done ASAP. I cannot wait week or even days. Read first 4 bytes of SWF file. First 3 bytes are Signature which reads (CWS or FWS) and next byte is SWF file version. So you don't need any library, just simple File IO will suffice. For actionscript version you need to look for FileAttributes Tag. So here is pseudo code for doing this. (in SWF file data is in Little Endian, so write your readInt or readShort function accordingly). [login to view URL]
