I work on PHP code with NetBeans and Xdebug. I use Xdebug for step-by-step debugging and the like.
I'm able to debug the flow of the default request, but not the flows generated by specific _get/_post or Ajax requests.
Anybody has an idea how can this be done?
When I run the debugger, a tab in my browser opened automatically with the following URL:
http://localhost/?XDEBUG_SESSION_START=netbeans-xdebug
Thanks.

Ok,
it goes this way:
At the projects tab (top left of the screen in my configuration), right click on the name of the project, and then properties => run configuration
There you have to fill 3 forms:
1. project url - the base url of the project on web, typically http://localhost
2. index file - use the browse button and go to the local copy of index.php or whatever file serves this role for you. This form should contain the path to this file in the local filesystem , not on the web
3. arguments - any arguments you wish to path to your script through the URL
This should give you the ability to choose a custom URL for debugging
A possible problem: in this process you may loose the synchronization between web addresses and the corresponding files in your system. Google "path mapping in php debugger" if you encounter issues of this nature, and take the first result (which the system wouldn't allow me to link directly).
However this didn't work for me. I used server configuration to overcome this issue by redirecting URLs

p.s.
All the above doesn't explain how to pass POST variables to your script while debugging (and I indeed don't know how to do it)
Perhaps you try to start a debug session as described above. As debug target you choose the nearest page to your POST request in the workflow. Then you interact with the web service, always having the debugger in netbeans running. With the interaction the debug session holds on, so you can fill forms etc. and send the POST request. Then switch to netbeans and debug as usual.
Perhaps you have to enable 'Break at first line' in the debug options, or set up a breakpoint in the php code, where the request is dispatched, in order to ensure the debugger halts while dispatching the POST request. Then you eventually will have to give the debugger a push at every page load.
Hope it helps

Recently I have tried to write a code in Symfony on page redirect (merely simple code for redirect without any other function), run it on localhost. However, the response returned is quite slow somehow (~500ms). What would be the possible cause of this as Laravel page redirect is faster than this.
When you open the Symfony profiler (just click on the debug toolbar that gets displayed in the bottom of the pages if you are in a development environment) there is a "Last 10" requests button you can click to view profiler information for last couple of requests.
Find your request that returned the redirect response, click on the Token value and you will be able to see in the "Performance" page what is causing the slowdown.
Also, when in development mode some of the changes that you make will require the container to be rebuilt and this can take a while in the development environment with xdebug enabled.
I have a PHP service and calling page which I am attempting to debug in Eclipse (Xdebug).
Both are part of the same project.
I can easily set up the calling page for debug and step through the code.
When I get to the point where the calling page calls the service (POST) it goes forward without debugging and continues stepping through the calling page.
So, what I tried to do is set up to debug on the service page then browse to the calling page in a browser - ensuring that it posts to the service page using debug querystring - It does not debug the service but instead steps through the calling page.
Eclipse is new to me and I've worked mostly with Visual Studion / WCF with services. In that environment, I would start two instances of VS - one running the service, the other, the calling page. When the service was invoked, the debugger would automatically step through. I'm trying to achieve the same thing in Eclipse.
Again, the goal is to step through the service after it has had the proper test data posted to it (by any means).
Is there some other way to do this in Eclipse?
Thanks in advance.
I have an Android application that is connectiont to a web server running MySQL DB. On the web server I have php files that run scripts and return JSON Objects to the client (application). I recently upgraded the versions of my web server and as of then, the SELECT statements are no longer returning anything to the client if they have parameteres, however if I run a SELECT with no parameters, it works fine. Has anyone ever encountered a similar problem?
To be more clear about my question:
Is there anyway I can debugphp scripts?
I thought maybe debugging via a web browser wouldn't work because the client is triggering the php files directly and not a direct access to the web.
All help is much appreciated!
Chrome has a set of tools that let you remote debug from your android.
Check them out: https://developers.google.com/chrome-developer-tools/docs/remote-debugging
You could wirte your own error handler an let him wirting some debug informations to a own log-file. than you can read the log file and check it for errors
Look at the MySQL error log and the php error log on your server
Check you activated the correct php_mysql* extensions in the newly upgraded PHP
Run the scripts on the server through a browser with the same parameters that your app uses, watch for errors
Upgrade the PHP code running on the server so it captures any errors and does something OBVIOUS with them.
I would recommend to use XDEBUG for debugging PHP code, or any analogue for yours web server. It is really simple to set-up and use it with any PHP IDE (like Netbeans) and it gives you a lot of abilities to explore your application condition. There is no difference in what browser you will open link with ?XDEBUG_SESSION_START=netbeans-xdebug parameter.
Also you can watch MySQL and Web-server logs.
If you cannot do anything above and you need to watch network action (AJAX requests), you can set-up ADB and use chrome developer console for debugging js (or to see php var_dump() in ajax calls) in you android chrome browser.
If you need to debug js in native android browser - try to redirect to "about:debug" page, and after this you will be able to see browsers js console (in some cases this button appears only when console has something to show - error or any othe message, in some cases it just doesn't work).
Update Watch Duplicate Copy Move
As mentioned by others, you can debug using the error logs given by mysql and php. There are also IDEs which come with debugging tools for scripting languages like php.
With an IDE like phpStorm by JetBrains, which I highly recommend using over just a normal text editor, you can configure data sources like a connection to your MySQL db. This is useful because you can run scripts in the IDE and see whether it's the retreival of the data from your db or something in your scripts or handling of the JSON object back in the client. So if you configure a data source and run those same scripts and you get the correct data back then you know there is either something wrong in the code where you send the data or something wrong in the code where you receive it.
**p.s. I know that I am 5 years (oh my days its been 5 years since 2013) late to this post but none the less you never know who may be having this same issue and they stumble accross this answer
1st - Setup Xdebug for remote debugging with your IDE(Eclipse, PHPStrom, etc), and put breakpoints in your script.(for example here's link for setting up eclipse envirompment).
2-nd - When sending your url request to server add parametres to your url(http://your/url.php&XDEBUG_SESSION_START=ECLIPSE_DBGP&KEY=XXXXX,
-1st parameter - XDEBUG_SESSION_START=ECLIPSE_DBGP starts debugging session. (as for me I am using eclipse IDE for developing, so my key will be ECLIPSE_DBGP).
-2nd parameter - KEY=XXXXXX - is a session number(type any number here).
After that you'll get your code breaks at your debugging point in your script.
I've got a nice question here :)
I need to debug my web service written in PHP. Its client is written in C#.
After a couple of days of searching I realized this is not an easy task. At least it seems nobody knows the right solution.
What is the problem in, actually?
We have 2 popular PHP debugging libraries : PHP Debugger from NuSphere and XDebug extension.
The problem is they both are controlled from URL query string or with the help of cookies. For example, to enable debugging with PHP Debugger you need to add ?DBGSESSID=xxx parameter to your URL or to have DBGSESSID cookie.
But when your web service is called from the external client, the client doesn't have a cookie and doesn't add DBGSESSID url parameter. So how can we debug in this situation?
PS. I don't want to write to log files, see request and response headers/data or something like this. I want normal step-by-step debugging and breakpoints.
Anyone?
Well, I am answering to myself.
If we use PHPEd & DBG, then we can use the magic function DebugBreak().
Make sure PHPEd & PHP DBG Listenere are running, write
DebugBreak('1#127.0.0.1');
anywhere in your werbservice's code, make a call from the client, and voila! - you are in PHPEd on that line in debugging mode!
you could set xdebug.remote_autostart to 1 to always debug (no request parameter needed). this could be limited to some url with the <Location> or <Files> directive.
Or just log some debug information (using Zend_Log or Pear Log if you want a generic library) using var_export.
quick and dirty way is:
file_put_contents('/tmp/log1.txt',
var_export(array($_REQUEST, $something), true));
You could write data to a log file (meh).
Or output debugging information in response headers (if the client can view them). But as far as using breakpoints, you may be out of luck.
You could also look into connection hijacking on your local computer (something similar to the Firefox AddOn Tamper Data) where you can interrupt the request and add the url parameter.
Try SoapUI to issue requests manually and get the detailed responses. Not sure if you can fake the cookie, but you can control the endpoints, and therefore the URL to an extent.
I seem to remember that you can configure NuSphere's product to automatically attempt to connect to the debug listener with or without the DBGSESSID parameter (in query string or cookie). I'm not positive if that's the case, though. However, you can get the effect you're looking for by doing the following. It may be a little more manually intensive than you're hoping for.
Setup some sort of HTTP query/response listener.
Perform desired access against web service from client.
Manually re-issue those requests, appending the appropriate DBGSESSID
For a little more initial setup, but lower friction debugging later:
Configure your client to access an alternate URL.
Setup a proxy to listen on that URL (for debugging, I've seen Privoxy recommended, though I have no experience with it personally).
Configure the proxy to forward all requests to the real web service, appending an appropriate DBGSESSID parameter or including the cookie
I use the plugin Poster to help debug my php Webservice
Edit :
Found a better tool to debug web service : Advanced REST client Application
It's a Chrome Plugin, works great to test all kind of web services that use REST
I am developing a web application.
I would like to extend my error messages (and their backtraces) so that I can click on the mentioned file, and have it opened automatically in my PHP IDE.
I would like to make this a easy-to-activate feature so that whoever works on the web application, can easily map the error message to point to their local copy of the site, and open their IDE.
What - short of developing a custom FF extension - is the simplest way you can think of to execute a local command (a batch file that calls the IDE) on click in Firefox on Windows(7)?
I have looked for extensions but had no luck. Maybe using another extension like Firebug or Greasemonkey?
Security is not an issue, as this is supposed to work on the developer's workstation only and I can change my local Firefox's settings.
You can add a new protocol (like "edit://") to windows (http://msdn.microsoft.com/en-us/library/aa767914(VS.85).aspx) and write a small handler program that picks a filename from the "edit://" url and passes that file to the editor. This way i taught windows to understand txmt links (http://blog.macromates.com/2007/the-textmate-url-scheme/) in the way my mac does.
There's not a way to do this with javascript. But it looks possible with a firefox addon. Have a look at this.
http://mozex.mozdev.org/
MozEX is an extension which allows the user to use external programs for these actions:
* edit content of textareas (possibly utilizing a spell-checker, color syntax etc.)
* view page source
* handle mailto, news, telnet and FTP links
* download files
* ... and many more :)
The universal handler lets you enter a list of protocol schemes, e.g., "abc://,def://" and a
command to handle them. So you just have your application generate a url that begins with
your chosen (made up) protocol, and mozex will intercept a click on the url and send the
url to your chosen command as a paramater.
I think this is exactly what you want.
I think that the closest you can get to this, is by having the configuration of the web browser associate a particular mime type with a given "helper application" (here the IDE program), and to have the HTTP server return such a file.
Otherwise, security concerns dictate that browser would not run any "abritrary" program/logic on the client.
Pekka,
After reading the thread so far, it seems that you want to build an application that somehow authenticates with the server--i.e.: the "average user" wouldn't have access to it. If this were the case, then delivering it through the browser is an impossibility without writing a custom extension.
Running authentication through GreaseMonkey is difficult, but once the client is authenticated, there is no real way to "run" the trace.
If the server generates a batch file or some kind of instruction set (script, shortcut, etc.), you can simply configure the browser (or have the local instance of your app configure the browser) to run the file. The problem here is that you have no way to automatically authenticate!
The only other way I can imagine that you could get this to work is via a Java applet, which would only be cumbersome and require Java to initialize every time you wanted to import a trace.
The problem you have is that the browser is inherently secure. It's designed to protect the computer from malware, rogue websites, etc etc., and so without developing a custom extension for the browser, there's no way to make the hop to any applications that run in tandem with the browser.
So on that note, I'll suggest that you reconsider writing a Firefox XUL extension as mentioned above. You'll probably need to implement some XPCOM code to make it work, too. Here are some resources that will help get you started:
https://developer.mozilla.org/en/xpcom
https://developer.mozilla.org/En/XUL

https://developer.mozilla.org/en/XUL_Tutorial/Introduction
I don't know which IDE you're using, but in for example Eclipse you can also use the built-in webbrowser to test your webapp and the exceptions/traces in the Eclipse console log already have links to the source code in question. Easy as that. See if your IDE provides something similar.
