function FormatReArray(str)
dim temp,sindex,temp1
temp=str&","
temp1=split(temp,",")
for sindex=0 to ubound(temp1)
 if temp1(sindex)<>"" then
 temp=replace(temp,temp1(sindex)&",","")
 temp=temp&temp1(sindex)&","
 end if
next
FormatReArray=left(temp,len(temp)-1)
end function

Function ReplaceReg(str,patrn,replStr,Ignor)
'=========================================
'参数解释:
'str 原来的字符串
'patrn 要替换的字符串（正则表达式）
'replStr 要替换成的字符串
'Ignor 是否区分大小写(1不区分,0区分)
'=========================================
 Dim regEx ' 建立变量。
 If Ignor=1 Then Ignor=true else Ignor=false
 Set regEx = New RegExp ' 建立正则表达式。
 regEx.Pattern = "("&patrn&")" ' 设置模式。
 regEx.IgnoreCase = Ignor ' 设置是否区分大小写。飞飞Asp技术乐园
 regEx.Global=True
 ReplaceReg = regEx.Replace(str,replStr) ' 作替换。飞飞As，p技术乐园
End Function

'函数使用参数说明
'Content: 需要执行添加隐藏关键字的文字、段落、文章
'RndKeyWordCount: 添加隐藏关键字的个数
'AllKeyword: 要添加到文章中的文字【要向段落末尾添加的关键字,多关键字请使用"|"分割】
'AllSign 添加到关键字中特殊符号【向关键字中添加随机特殊符号，多特殊符号请使用"|"分割，特殊符号请勿使用"|"】
'HiddenColor: 要添加到文章中的文字的颜色（和背景色相同，达到隐藏的目的）
'*********************************************
'使用的外部函数有
'1.ReplaceReg [正则表达式替换关键字]
'2.FormatReArray [去除数组中的重复项]
'*********************************************
'使用实例：
'Response.Write(HiddenKeyword("aaaaaaaaaaaa bbbbbbbbbbb ccccccccc ddddddddd eeeeeeeeeeeee",3,"飞飞Asp乐园|ffasp",",|.|。|，|@|！","ff0000"))
'请查看源代码查看效果
