介绍一组中文处理工具函数
<?
/* 中文处理工具函数
--- 空格 ---
string GBspace(string) --------- 每个中文字之间加空格
string GBunspace(string) ------- 每个中文字之间的空格清除
string clear_space(string) ------- 用来清除多余的空格
--- 转换 ---
string GBcase(string,offset) --- 将字符串内的中英文字转换大小写
offset : "upper" - 字符串全转为大写 (strtoupper)
"lower" - 字符串全转为小写 (strtolower)
"ucwords" - 将字符串每个字第一个字母改大写 (ucwords)
"ucfirst" - 将字符串第一个字母改大写 (ucfirst)
string GBrev(string) ----------- 颠倒字符串
--- 文字检查 ---
int GB_check(string) ----------- 检查字符串内是否有 GB 字，有会返回 true，
否则会返回false
int GB_all(string) ------------- 检查字符串内所有字是否有 GB 字，是会返回 true，
否则会返回false
int GB_non(string) ------------- 检查字符串内所有字并不是 GB 字，是会返回 true，
否则会返回false
int GBlen(string) -------------- 返回字符串长度（中文字只计一字母）
--- 查找、取代、提取 ---
int/array GBpos(haystack,needle,[offset]) ---- 查找字符串 (strpos)
offset : 留空 - 查找第一个出现的位置
int - 由该位置搜索出现的第一个位置
"r" - 查找最后一次出现的位置 (strrpos)
"a" - 将所有查找到的字储存为数组(返回 array)
string GB_replace(needle,str,haystack) -- 查找与取代字符串 (str_replace)
string GB_replace_i(needle,str_f,str_b,haystack) -- 不检查大小写查找与取代字符串
needle - 查找字母
str - 取代字母 ( str_f - 该字母前, str_b 该字母后)
haystack - 字符串
string GBsubstr(string,start,[length]) -- 从string提取出由开始到结尾或长度
length的字符串。
中文字只计一字母，可使用正负数。
string GBstrnear(string,length) -- 从 string提取最接近 length的字符串。
length 中 中文字计2个字母。
--- 注意 ---
如使用由 Form 返回的字符串前，请先替字符串经过 stripslashes() 处理，除去多余的 \ 。
用法：在原 PHP 代码内加上：
include ("GB.inc");
即可使用以上工具函数。
