ASP functions to PHP?

is there anyway I can make these ASP functions into PHP functions and how would i use them?


Function EncodeSQL(VarVal)
EncodeSQL=Replace(VarVal,"'","`")
End Function

Function DecodeSQL(VarVal)
DecodeSQL=Replace(VarVal,"`","'")
End Function

function encode_stuff($str){

$str1 = str_replace("'", "`",$Str);
return $str1;

}


Hope this solves your problem.
