Perl中如何匹配汉字?为什么
$ perl -e 'if ( "中国" =~ /\p{Han}/ ) { print "!"}' $
不工作?
如果您的源代码是 UTF-8,则需要使用use utf8;. 如果不是 UTF-8,则源中不可能有任何汉字符。
use utf8;
$ perl -le'use utf8; if ( "中国" =~ /\p{Han}/ ) { print "!" }' !
我有一个带有集成 CKeditor 的 cms。Ckeditor 替换<?php with <!--?php. 我想在 ckeditor 中编写 php 代码"<div><?php $prod=products($cat_id); ?>....</div>"并将其存储到 MySQL DB.. 并且在查看器的页面上我想输出
<?php with <!--?php
"<div><?php $prod=products($cat_id); ?>....</div>"
