这里有几个asp函数
我想要改写成对应的php函数
请问要怎么写?
谢谢~~~
//第一个就是编码转换,可以把任何charsets 都转为utf-8
'==================================================
'函数名:BytesToBstr
'作 用:将获取的源码转换为中文
'参 数:Body ------要转换的变量
'参 数:Cset ------要转换的类型
'==================================================
Function BytesToBstr(Body,Cset)
Dim Objstream
Set Objstream = Server.CreateObject("ad" & "odb.str" & "eam")
objstream.Type = 1
objstream.Mode =3
objstream.Open
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = Cset
BytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
End Function
//第二个就是post 然后获得post之后页面的代码
'==================================================
'函数名:PostHttpPage
'作 用:登录
'==================================================
Function PostHttpPage(RefererUrl,PostUrl,PostData)
Dim xmlHttp
Dim RetStr
Set xmlHttp = CreateObject("Msx" & "ml2.XM" & "LHT" & "TP")
xmlHttp.Open "POST", PostUrl, False
XmlHTTP.setRequestHeader "Content-Length",Len(PostData)
xmlHttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
xmlHttp.setRequestHeader "Referer", RefererUrl
xmlHttp.Send PostData
If Err.Number <> 0 Then
Set xmlHttp=Nothing
PostHttpPage = "$False$"
Exit Function
End If
PostHttpPage=bytesToBSTR(xmlHttp.responseBody,"utf-8")
Set xmlHttp = nothing
End Function
//第三个就是裁剪字符串
'==================================================
'函数名:GetBody
'作 用:截取字符串
'参 数:ConStr ------将要截取的字符串
'参 数:StartStr ------开始字符串
'参 数:OverStr ------结束字符串
'参 数:IncluL ------是否包含StartStr
'参 数:IncluR ------是否包含OverStr
'==================================================
Function GetBody(ConStr,StartStr,OverStr,IncluL,IncluR)
If ConStr="$False$" or ConStr="" or IsNull(ConStr)=True Or StartStr="" or IsNull(StartStr)=True Or OverStr="" or IsNull(OverStr)=True Then
GetBody="$False$"
Exit Function
End If
Dim ConStrTemp
Dim Start,Over
ConStrTemp=Lcase(ConStr)
StartStr=Lcase(StartStr)
OverStr=Lcase(OverStr)
Start = InStrB(1, ConStrTemp, StartStr, vbBinaryCompare)
If Start<=0 then
GetBody="$False$"
Exit Function
Else
If IncluL=False Then
Start=Start+LenB(StartStr)
End If
End If
Over=InStrB(Start,ConStrTemp,OverStr,vbBinaryCompare)
If Over<=0 Or Over<=Start then
GetBody="$False$"
Exit Function
Else
If IncluR=True Then
Over=Over+LenB(OverStr)
End If
End If
GetBody=MidB(ConStr,Start,Over-Start)
End Function








怎么把这三个asp函数改写成php的?
