When posting your question please:

Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
No advertising or soliciting.
We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.

When answering a question please:

Read the question carefully
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
If the question is inappropriate then click the 'vote to remove message' button

Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.

Ajax and PHP

Hi, I'm a total newbie to JavaScript, Ajax and PHP, so please excuse any stupid question I might ask.

So, I'd like to use a lazy loading TreeView which gets it's data from a database via PHP. I found a JavaScript control to use and an example to try out, and now I have a question.

To lazy load the data for the expanded tree node I need to fire an Ajax request to a PHP file which gives me the answer as a JSON stream. In the example I'm trying out this PHP file only delivers one string (with 'echo'), but what do I have to do if I need to loop through a database recordset. Can I 'echo' every partial answer to my lazy loading treeview as I get it from the database or do I need to collect the complete answer inside the PHP file in a string variable and send it only when it's complete?

I hope you understand my question.

Thanks for any answer or advice in advance.

No there is no real difference between lots of little echoes and one big one with the same content. Depending on your server and its buffering policy, you might find little ones a bit faster.

I have a web service, it requires authentication to call functions but I couldn't authenticate.
 
The function XML is like this:
 
    <s11:Envelope xmlns:s11='http://schemas.xmlsoap.org/soap/envelope/'>
      <s11:Header>
        <ns1:AuthHeader xmlns:ns1='MOD'>

          <ns1:Username>?XXX?</ns1:Username>
    <!-- optional -->
          <ns1:Password>?XXX?</ns1:Password><!-- This element can be extended by any attribute from any namespace -->
        </ns1:AuthHeader>

      <s11:Body>
        <ns1:GetBankList xmlns:ns1='MOD' />
      </s11:Body>
    </s11:Envelope>
 
my connection codes are:
 
    $baglanti = new :confused:SoapClient("https://galaksi.turknippon.com/appservice/mod.asmx?wsdl");
    $parm = array();
    $parm[] = new SoapVar('channelcode', XSD_STRING, null, null, 'Channel' );

Please verify that the code as it's shown in your previous message matches your actual code (and that it's not mangled somehow by mistake when inserting it into the message). Because the JavaScript in index.php doesn't run for me, there's a syntax error.

Ecrypt PHP Application

Hi,

I have a local network at the company and I want to have PHP applications on the server but is there any way to encrypt the files so no one will be able to read the source code even if they go physically on the server?

Thanks,

You could use Zend Guard - but it is a bit expensive if all you want to do is stop people who have access to the server poking around in the source code.
