Flash unescape vs. php urlencode

Question

Hi, the thing is more or less like this: i am sending from some flash app some text to be stored in a database. before i keep it in the database, in the server side, i escape (or in this case i urlencode, the server script is in php). it stores the escaped or url encoded string before attaching it to a sql sentence, hopefully without "s or 's. now to retrieve it, i get it inside an xml node, so it comes just as it was kept in the database (if i have gotten it in a urlvar it would have come unescaped). when i unescape it ant display it, the spaces are replaced by '+'. i have tried trhis page:

it seems to get it right either in php format (with +), or with flash (with %20), seems to be equivalent. how do i set them to agree, between the flash and php escapes? are there any alternative ways either in flash or in php to url-encode, or does any of those receive parameters?
tnx

Answer 1

decided to implement my own 'flash_compatible_encode' php escape.
var _array_con:String = "$_conv = array(";
var _cont:Number = 0;
var _char:String;
while (_cont<255) {
    _char = String.fromCharCode(_cont);
    _array_con += "\"" + escape(_char) + "\", ";
    _cont += 1;
_array_con += ");";
trace(_array_con);
// remove the last comma, then use 'ord' in php as search index
