LINUX脚本去除PHP末尾的闭合标签，避免莫名的空字符

PHP文件比较多的情况下，有时候不知道为什么就多出空格，可能会影响COOKIE不能写等等情况。

这个LINUX脚本可以去除PHP末尾的闭合标签，避免莫名的空字符

#!/bin/bash
# vim:ft=sh:ts=3:sts=3:sw=3:et:

###
# Strips the closing php tag `?>` and any following blank lines from the
# end of any PHP file in the current working directory and sub-directories. Files
# with non-whitespace characters following the closing tag will not be affected.

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;
