fwrite is adding blank lines

attached is a script i wrote to open a file, display it's contents in a textarea, then submit to a different case where the file is re-written. what i notice is that when there is a blank line, after re-writing that blank line gets doubled. so there are now two blank lines where there was one. why is this? anyone know how to prevent this from happening? many thanks for you help. benjamin begin 666 portal_edit.php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`` ` end
