conversione ASP-PHP

[harpox]

Non conosco ne l'ASP ne il PHP, quindi cerco una buon'anima che mi convertisse questo script ASP in PHP.

<%

note = request.form("note")
note = replace(note,"%","%25")
note = replace(note,"&","e")
note = replace(note,"'","''")
idCampo=request.form("idCampo")
idCampo = replace(idCampo,"'","''")
if len(note) > 0 and len(idCampo) > 0 then
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open "DRIVER={Microsoft Access Driver (*.mdb)};" &_
"DBQ="& Server.MapPath("/mdb-database/note.mdb/")
sql = "INSERT INTO foglio (messaggio,idCampo)  VALUES('" & note & "','" & idCampo & "')"
Conn.Execute(sql)
conn.close
set conn = nothing
else
idCampo=request.queryString("idCampo")
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open "DRIVER={Microsoft Access Driver (*.mdb)};" &_
"DBQ="& Server.MapPath("/mdb-database/note.mdb/")
sql = "SELECT top 1 * FROM foglio where idCampo="&idCampo&" order by id desc"
Set Rs = Conn.Execute(sql)
If Rs.EOF Then
commento=" " 
Else
Do Until Rs.EOF
commento=commento&rs("messaggio")&"

"
Rs.MoveNext
Loop
End If
Rs.Close
Set Rs = Nothing
Conn.Close
Set Conn = Nothing
end if
