Pls help jolt my old memory with this? Trying to work on some old php
progs that output using the json_encode function on a NEW install of
Ubuntu 13.10. I'm NOT getting any output. If I dump the array I'm
using as the source for the json_encode it looks just fine. However,
firebug is showing non response.

I checked with phpinfo and it shows that I do have json installed and
active and when I try to run the target program I also receive just
errors.

So my question is: can someone recommend some ways to properly debug
the ajax/json process? I seem to remember firebug once having some
features available to examine the response from a js call but I don't
see it now.

BTW - having just recently upgraded from 10.04 to 13.10 I've run into
other issues with compatibiity. Hopefully they are getting resolved
and this is just one of them.

Thanks for any advice/suggestions.

Have you checked the server logs to make sure the page being accessed
isn't generating a fatal PHP error and stopping the script?

Hi,

I still use json_encode like crazy, it works fantastic, no issues so
far;

You need to test two places
- On the php, ensure that you actually get something rendered. Are you
sure the php array or object is valid ? That is simple to test, put a
breakpoint there and run in debug, you figure out fast

- On the browser side, I assume you use some javascript framework,
jQuery or something. If you don't, please do it, it saves headache and
time. It is possible that the json crashes when it gets evaluated,
although if it is generated with json_encode this is less likely to
happen: locate you callback function and place a breakpoint in the
javascript code and see what comes.

Personally rather than leaving jQuery to eval my json, I prefer to
take the response as text and eval it myself - in between these two
likes of code, you can always alert(responsetext) and see what comes
back.

That always worked for me...

BTW, one thing - json_encode I don't believe that relies on an
external library, it was always there when I installed php;

In php you should have the code looking like:

$myVar = json_encode( $arr );
echo $myVar;
?>

In firebug:
place a breakpoint at the first line of code in the callback function.
The returning data is actually the error message from php and can not processed correctly.

jnorth.au, you and BobMCT both need to reconfigure your Avast programs to
remove the auto-insertion of the above spam messages. Thanks for your
consideration. It's caused by your recently updated version, and it also
has a malformed sig delimiter which causes it to be quoted by the unwary.

*Where* does it show “non response” (sic!)? *How?*

If in the Network tab, there are two possibilities:

A) You are not making an HTTP request with the correct URI.
B) You are not sending a non-empty HTTP response.

If A), you have to check the client-side script and Firebug's error console.
If B), you have to check the server-side script. Make sure that there are
no syntax errors or other PHP errors. The first lines of your PHP program
should be:

<?php
error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', true);

ini_set() is necessary (except on a development system where the value
should be the default) unless you want/have to check the PHP log files
instead.

*Which* errors?

In addition to the above, there is the FirePHP add-on.

They still are in the Network tab and the Console. <http://getfirebug.com/>

Of what?

Useless information again.

Perhaps this:

< http://askubuntu.com/questions/361424/what-happened-to-json-encode-in-13-10 -php>

With PHP 5.5 on Ubuntu 13.10 php5-json has to be installed explicitly.

Good catch! Regarding the explanation[1] that is linked from a comment:

| The response from PHP has been to remove the standard PHP JSON
| extension as of PHP 5.5rc2.

AFAIK, JSON has not been removed from PHP, but rather from some
distributions.

OT: in firebug, how does one set a breakpoint ?

you open the script in browser (start with right click - explore
element and from there go to the tab with the script, and set the
breakpoint.

Chrome is better in terms of debugging than Firefox with Firebug. Try
it.

For other questions please post in the right nntp group this is not
php

Thanks for all the responses/suggestions. Being a newly installed
version of Ubuntu 13.10 Server I DID have to explicitly install the
php5-json package. Guess what? Now it works - gee.

And just one comment to "pointed ears" - get a life, huh!
