in thread Read/Update File

Thank you for the post. Most helpful. :-) I've been trying to use +> to open the file for read/write purposes but cannot read the contents in. I'm trying to read the contents into an array such as (simpler version) but it isn't working :
open (FH, ">+path"); my @lineArray = <FH>; print join("<br>", @lineArray); # nothing prints although the file do +es have content
Is there something I have to do with buffering? Reading from the handle in this way is no good when opening for read/write? Any help on this would be most appreciated as well. Thanks.

    > means clobber (overwrite) file , means you get empty file each time, you want +< for read/write. See open
