推荐答案
我想要同样的东西,所以我编写了这样的代码: 如果无法获取版本信息,则返回FALSE,否则返回包含文件版本字段(数字,以.分隔)的四个元素的ARRAY.它仅适用于32位PE文件(因为我不需要其他文件)格式).
I wanted the same thing, so I coded this: It returns FALSE, if it can't get the version info, or an ARRAY of four elements with file version fields (numbers, which are separated by .) It works only for 32-bit PE files (as I had no need for other formats).
function GetFileVersion($FileName) {
$handle=fopen($FileName,'rb');
if (!$handle) return FALSE;
$Header=fread ($handle,64);
if (substr($Header,0,2)!='MZ') return FALSE;
$PEOffset=unpack("V",substr($Header,60,4));
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));
if ($Machine[1]!=332) return FALSE;
$NoSections=unpack("v",substr($Header,6,2));
$OptHdrSize=unpack("v",substr($Header,20,2));
fseek($handle,$OptHdrSize[1],SEEK_CUR);
$ResFound=FALSE;
for ($x=0;$x<$NoSections[1];$x++) { //$x fixed here
$SecHdr=fread($handle,40);
if (substr($SecHdr,0,5)=='.rsrc') { //resource section
$ResFound=TRUE;
break;
}
}
if (!$ResFound) return FALSE;
$InfoVirt=unpack("V",substr($SecHdr,12,4));
$InfoSize=unpack("V",substr($SecHdr,16,4));
$InfoOff=unpack("V",substr($SecHdr,20,4));
fseek($handle,$InfoOff[1],SEEK_SET);
$Info=fread($handle,$InfoSize[1]);
$NumDirs=unpack("v",substr($Info,14,2));
$InfoFound=FALSE;
for ($x=0;$x<$NumDirs[1];$x++) {
$Type=unpack("V",substr($Info,($x*8)+16,4));
if($Type[1]==16) { //FILEINFO resource
$InfoFound=TRUE;
$SubOff=unpack("V",substr($Info,($x*8)+20,4));
break;
}
}
if (!$InfoFound) return FALSE;
$SubOff[1]&=0x7fffffff;
$InfoOff=unpack("V",substr($Info,$SubOff[1]+20,4)); //offset of first FILEINFO
$InfoOff[1]&=0x7fffffff;
$InfoOff=unpack("V",substr($Info,$InfoOff[1]+20,4)); //offset to data
$DataOff=unpack("V",substr($Info,$InfoOff[1],4));
$DataSize=unpack("V",substr($Info,$InfoOff[1]+4,4));
$CodePage=unpack("V",substr($Info,$InfoOff[1]+8,4));
$DataOff[1]-=$InfoVirt[1];
$Version=unpack("v4",substr($Info,$DataOff[1]+48,8));
$x=$Version[2];
$Version[2]=$Version[1];
$Version[1]=$x;
$x=$Version[4];
$Version[4]=$Version[3];
$Version[3]=$x;
return $Version;
}
