PHP中怎么限定上传文件的格式为doc或者docx

function NewUploadFile( $jpg, $jpg_type, $fname, $jpg_size, $path )

{

global $strDownNotice9

global $strDownNotice11

if ( $jpg_size == 0 )

{

$arr[0] = "err"

$arr[1] = $strDownNotice9

return $arr

}

if ( substr( $fname, -4 ) != ".doc" &&substr( $fname, -5 ) != ".docx" )

{

$arr[0] = "err"

$arr[1] = $strDownNotice11

return $arr

}

$hzarr = explode( ".", $fname )

$num = sizeof( $hzarr ) - 1

$UploadImage[2] = $hzarr[$num]

$timestr = time( )

$hz = substr( $fname, -4 )

$file_path = ROOTPATH.$path."/".$timestr.$hz

$UploadImage[3] = $path."/".$timestr.$hz

copy( $jpg, $file_path )

chmod( $file_path, 438 )

$UploadImage[0] = "OK"

$UploadImage[1] = "OK"

return $UploadImage

}
