do
        FILES=$(pcregrep -rnM --include='^.*\.php$' '^\?\>(?=([\s\n]+)?$(?!\n))' .);

        for MATCH in $FILES;
        do
           FILE=`echo $MATCH | awk -F ':' '{print $1}'`;
           TARGET=`echo $MATCH | awk -F ':' '{print $2}'`;
           LINE_COUNT=`wc -l $FILE | awk -F " " '{print $1}'`;
           echo "Removing lines ${TARGET} through ${LINE_COUNT} from file $FILE...";
           sed -i "${TARGET},${LINE_COUNT}d" $FILE;
        done;
done

in case you have several newlines behind ?> make sure to exec the script multiple times!
