Special characters in String variable sent from php.

[klinek3]

Hello. Assuming that I send some String variable from php into flash:

AS3:

var MyImportedString:String;

var variables_page_text:URLVariables = new URLVariables();

var varSend_page_text:URLRequest = new URLRequest("MyPHP.php");

varSend_page_text.method = URLRequestMethod.POST;

varSend_page_text.data = variables_page_text;

var varLoader_page_text:URLLoader = new URLLoader;

varLoader_page_text.dataFormat = URLLoaderDataFormat.VARIABLES;

varLoader_page_text.addEventListener(Event.COMPLETE, var_comp_page_text);

varLoader_page_text.load(varSend_page_text);

function var_comp_page_text(event:Event):void {

    MyImportedString =  event.target.data.MyVariable;

}

php:

<?php

header('Content-Type: text/html; charset=utf-8');

$MyString = "some tekst &";

print "MyVariable=" . $MyString;

?>

   I've noticed that the special character '&' residing inside String, throws an error:  #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.

  My first thought was, it has something to do with html entities, but other entities (like <> or ") don't throw any error. Besides, the use of php functions like htmlentities(); or html_entity_decode(); doesn't make any difference in this case:

print "MyVariable=" . htmlentities($MyString);

or

print "MyVariable=" . html_entity_decode($MyString);

  I've also noticed that characters like '%', '^', '+' don't show up at all;

  What does it mean? Any ideas?

  Reagards.

This function works in general pretty good:

<?php
    function flash_encode($string)
    {
       $string = rawurlencode(utf8_encode($string));

       $string = str_replace("%C2%96", "-", $string);
       $string = str_replace("%C2%91", "%27", $string);
       $string = str_replace("%C2%92", "%27", $string);
       $string = str_replace("%C2%82", "%27", $string);
       $string = str_replace("%C2%93", "%22", $string);
       $string = str_replace("%C2%94", "%22", $string);
       $string = str_replace("%C2%84", "%22", $string);
       $string = str_replace("%C2%8B", "%C2%AB", $string);
       $string = str_replace("%C2%9B", "%C2%BB", $string);

       return $string;
    }
?>

Thank You 'moccamaximum'.

Ok. So here is the solution (php function posted by 'moccamaximum' does the trick):

AS3:

var MyImportedString:String;

var variables_page_text:URLVariables = new URLVariables();

var varSend_page_text:URLRequest = new URLRequest("MyPHP.php");

varSend_page_text.method = URLRequestMethod.POST;

varSend_page_text.data = variables_page_text;

var varLoader_page_text:URLLoader = new URLLoader;

varLoader_page_text.dataFormat = URLLoaderDataFormat.VARIABLES;

varLoader_page_text.addEventListener(Event.COMPLETE, var_comp_page_text);

varLoader_page_text.load(varSend_page_text);

function var_comp_page_text(event:Event):void {

    MyImportedString =  event.target.data.MyVariable;

     trace(MyImportedString);        // Output:  some text &%^+

}

php:

<?php

header('Content-Type: text/html; charset=utf-8');

$MyString = "some text &%^+";

print "MyVariable=" . flash_encode($MyString);

function flash_encode($string){

     $string = rawurlencode(utf8_encode($string));

     $string = str_replace("%C2%96", "-", $string);

     $string = str_replace("%C2%91", "%27", $string);

     $string = str_replace("%C2%92", "%27", $string);

     $string = str_replace("%C2%82", "%27", $string);

     $string = str_replace("%C2%93", "%22", $string);

     $string = str_replace("%C2%94", "%22", $string);

     $string = str_replace("%C2%84", "%22", $string);

     $string = str_replace("%C2%8B", "%C2%AB", $string);

     $string = str_replace("%C2%9B", "%C2%BB", $string);

     return $string;
}
