        Hi everybody!

        I'm building a small ajax app which consists of only 3 php files.

        index.php which contains all the app and has a couple of
        links. When a
        link is clicked an Ajax request is sent to the server (using
        prototype)
        to the
        url central.php with only one parameter 'id'. Depending on that
        parameter, central.php should look for the appropiate
        content, in this
        case link1.php.
        Then I return a JSON object with the "things" that should be
        updated on
        index.php

        So this is the pseudo-code:

        index.php
        <html>...
        <body>
        <a href="" onclick="[send the Ajax request using prototype
        with the id =
        1]>Link #1</a>
        <div id="theUpdatableDIV"></div>
        </body>

        central.php
        <html>...
        <body>
        <?php
        [read the id parameter]
        switch(id){
            case 1: //which is the only case for now!!
               //build the JSON object
               $output = array("title" => "Link #1 Title!",
        "content"=>file_get_contents("link1.php"));//here I read the
        last file
        which has the content to be updated asynchronously
                return [the JSON object based on $output];
                break;
        }
        ?>
        </body>

        link1.php
        <div>Welcome to the content of link #1 which was updated using <a
        href=" ajax.org <http://ajax.org>">ajax</a></div>

        the JSON object is formed ok, now, my problem is that
        link1.php outputs
        like this:

        <div>Welcome to the content of link #1 which was updated
        using <a
        href="ajax.org <http://ajax.org>">ajax<\/a><\/div>

        So at the moment I update the <div id="theUpdatableDIV">
        element on
        index.php, I get no "real" content, but a string with the
        strange slashes.

        I've tried:
        stripslashes, ereg_replace, str_replace and strtr to
        eliminate the
        wierd slashes.

        Can anybody tell how to do it right?

    how are you building the json object?

    i recommend
    json_encode(utf8_encode($dataToEncode));

    if youre using php5.  if youre using php4, try this:
    http://mike.teczno.com/JSON/JSON.phps

    also, you might want to check out firebug for firefox.  it will
    let you
    easily analyze the interaction between the client and server.

    also, to verify that the json object youre generating is infact ok;
    run it through here:
    http://www.jslint.com/

    Hi Nathan,

    I'm using php5, and I'm building the JSON object just like that,
    with the json_encode.
    The problem with using utf_encode apart from the original is that
    I get the \n\r for each line in the file read.
    Any suggestions?

    Thanx

are you running windows? im guessing those are newline characters in windows format that arent getting interpreted correctly on the client side. you might try stripping out the newline characters prior to encoding the data. $jsonOut = json_encode(utf8_encode(str_replace("\r\n", '', $stringToEncode))); also, what are you trying to encode? if you are encoding arrays or objects (php that is) you will have to utf8_encode all the elements of those complex datums prior to handing them to json_encode() for the final output. -nathan Hi again Nathan, well I actually did that before, using the str_replace to eliminate al the windows \r\n, but the big problem isn't that the HTML code is being escaped too. I get something like <div>this is the content<\/div> it seems like the '/' is being escaped, but I need it as HTML. Balpo
