Get Version of exe via PHP

Question

Is getting the version of a exe possible with php? I\'d like to print the version of a file that can be downloaded...

Windows exe and php is running on linux server<

Elaborating on the answer Toni provided One of the projects at work had a custom attribute baked into that resource section. On a linux machine we didnt want to install perl to use the windows function to get the values. Instead one can use this variant of the GetFileVersion to get any value you are seeking. (FileVersion, ProductVersion, ProductName, CompanyName, CompanyWebsite) It should return false for values that dont exist, and it functions rather quick.

    if ($PEOffset[1]<64) return FALSE;
    fseek($handle,$PEOffset[1],SEEK_SET);
    $Header=fread ($handle,24);
    if (substr($Header,0,2)!='PE') return FALSE;
    $Machine=unpack("v",substr($Header,4,2));
