Netbeans file debugging - php

I have netbeans setup with xdebug so it can debug php. However, this only works if I create a php project. It will not work if I try opening a stand alone php file. So my question is, is it possible to debug a stand alone php file which is not part of a netbeans php project?
If that is not possible, how do I debug stand alone php files with netbeans?

No, There is none that I am aware of. As Myrddin mentioned the debugger needs some configurations that is a part of netbeans project.
but the best way you can debug a single file is to copy it on a project folder, and click the debug project, once the debug session is set then you can browse the PHP File that you want to debug and it will actually go through xdebug.
Good Luck!

Each project can have it's own configuration (you can have 1 project that has PHP5.4 interpreter, one the is PHP5.6, one that is a command line and another that is a web project), but if you configure a general PHP 5 Interpreter:
If you work on a windows machine you can use this code (filename is php.cmd)
set XDEBUG_CONFIG="idekey=netbeans-xdebug"
#php.exe %*
If you want to be able to debug, your interpreter should have the XDEBUG_CONFIG system variable and make sure it's connected to netbeans. You should set this to the same value in your Debbugging section of the PHP's config:
Next thing - if you right click inside the editor you will have the Debug File option, and a prompt window will pop:
You don't really need anything here. Just hit the "OK" button.
As you can see, this final result is debug session of the t1.php file within c:\TEMP\ (which is not a working project):

Short answer: CTRL + SHIFT + F5
You can find the answer here:
https://blogs.oracle.com/netbeansphp/entry/run_file_without_project

I'm not entirely sure, but I think it is not possible, because you need some configuration to get the debugging working, and this configuration is part of a project.
You can always use print_r and var_dump to debug a single file. But that is probably not the answer you're looking for.

xdebug is very heavy and old tool you can use Kint php debuger here.
its free, so you can download Here
it's pretty replacement for var_dump(), print_r() and debug_backtrace().
you need to add kint.class.php file using include or require function.
require '/kint/Kint.class.php';
that's it.
and you can use like
########## DUMP VARIABLE ###########################
Kint::dump($GLOBALS, $_SERVER); // pass any number of parameters
// or simply use d() as a shorthand:
d($_SERVER);
########## DEBUG BACKTRACE #########################
Kint::trace();

Good Luck :)

How to debug PHP CLI scripts from the CLI

Does anybody know how to debug CLI PHP scripts from the CLI?!? I don't want to debug a PHP web page - I don't have a PHP web page. I don't want to debug a remote script either - I'm running/debugging right here on this system. I don't want to (at this time) try to get some IDE (Eclipse, PhpStorm or whatever) to debug a CLI PHP rather I just want to debug some PHP CLI script at the Linux command line itself. In Perl this would be simply perl -d <script.pl> <options>. Debugging a script, to me, is not figuring out compile errors or other simple things. To me it's setting break points, running code, examine the contents of variables and being able to arbitrarily execute or eval ('<php code>') at the debugger.
Sure later I'd like to configure this into my IDE of choice (at this time this is Eclipse) but I have not managed to get that working. Debugging from the CLI a PHP CLI script would be a good start for me.
Thanks.
I don't know why I'm limited to a character count when posting a comment. Perhaps I can add more text here.
Here's what I have tried in order to use xdebug and/or Zend debugger with Eclipse:
Base Eclipse version Mars.1 Release 4.5.
Eclipse PDT UI Plugin version 3.7.0.2015112
Tried installing xdebug using pecl install xdebug. Says I need to add "zend_extension=xdebug.so" to php.ini. Really? Which php.ini? I have several:
Andromeda:sudo find / -xdev -name php.ini
/etc/php5/cli/php.ini
/etc/php5/apache2/php.in
/opt/eclipse/plugins/org.zend.php.debug.debugger.linux.x86_64_5.3.18.v20110322/resources/php53/php.ini
/opt/eclipse/plugins/org.zend.php.debug.debugger.linux.x86_64_5.3.18.v20110322/resources/php5/php.ini
/opt/eclipse/plugins/com.zend.php.debug.debugger.php56.linux.x86_64_13.0.1.v20151112-2045/resources/php56/php.ini
Andromeda:
I put the zend_extension thing in both /etc/php5/cli/php.ini and /etc/php5/apache2/php.ini. Made a phpinfo.php page and I see Xdebug in there (yea!). Configure a Debug Configuration in Eclipse to use xdebug and try to debug:
Launching renameUser has encountered a problem. An internal error occurred during "Launching renameUser" java.lang.NullPointerException.
Oh goodie...
I had also installed the Zend Debugger and added the following to those same two php.ini files:
zend_extension=/usr/lib/php5/20121212/ZendDebugger.so
zend_debugger.allow_hosts=127.0.0.1/32, 192.168.0.0/16
zend_debugger.expose_remotely=always
Changed debug configuration to use Zend Debugger and attempted to debug. Received:
Error launching 'renameUser' The debug session could not be started. Please make sure that the debugger is properly configured as a php.ini directive.
Restarted Eclipse and now the debugger attempts to run but simply terminates with a 255 exit value attempting to run /opt/eclipse/plugins/org.zend.php.debug.debugger.linux.x86_64_5.3.18.v20110322/resources/php5/php-cgi. Why it's runnign php-cgi is beyond me. I said this was a CLI not a CGI. In any event I get the following when trying to run this from the command line:
Andromeda:/opt/eclipse/plugins/org.zend.php.debug.debugger.linux.x86_64_5.3.18.v20110322/resources/php5/php-cgi
/opt/eclipse/plugins/org.zend.php.debug.debugger.linux.x86_64_5.3.18.v20110322/resources/php5/php-cgi: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory
Found a libiconv.so.2 in /opt/eclipse/plugins/org.zend.php.debug.debugger.linux.x86_64_5.3.18.v20110322/resources/lib and set LD_LIBRARY_PATH to include that but this just fails to launch the debugger at all stating to make sure that the debugger is properly configured as a php.ini directive... UGH!
Other odd stuff:
When Eclipse starts up it fails to open my RSE based project thus displaying edit buffers from the last run as empty
Eclipse will no longer exit! Select File: Exit. Nothing happens. Click on the X in the title bar - nothing happens. Now I have to kill it to close it!
When debugging on the command line you need to tell PHP you want to debug also
http://xdebug.org/docs/remote
says
export XDEBUG_CONFIG="idekey=session_name"
php myscript.php
assuming xdebug is enabled (it doesnt matter which .ini file its in, but there is a standard place per OS for this, usually in a conf.d folder called xdebug.ini which is auto included)
This allows you to debug a cmdline script.
Personally I use Vim with Vdebug extention (xdebug for vim) to debug and nothing other than a command line is needed
What worked for me was using dephpugger. I found the steps to get CLI debugging working here:
https://hackernoon.com/how-debug-php-applications-with-dephpugger-98cc234d917c
I had previously installed xdebug and tried out exussum's answer.
The steps I followed are included here for completeness.
Install dephpugger:
composer global require “tacnoman/dephpugger”:”dev-master”
Put dephpugger on the path:
export PATH=$PATH:$HOME/.composer/vendor/bin
make sure to include in the php file at the breakpoint:
xdebug_break();
open up 2 terminal instances. In one run:
dephpugger debug
In the other run
dephpugger cli /path/file.php
replacing /path/file.php with the path to your file. if you need command line arguments to the php script put the path and arguments in quotes. It still seems a little hacky. I think the real trick is to write in a language that has a better debugger built in.
exussums answer works for me.
In addition I have the following in /etc/php/7.0/cli/conf.d/20-xdebug.ini
zend_extension=xdebug.so
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.remote_enable=true
#xdebug.remote_enable=false
And I had to do this: https://github.com/vim-vdebug/vdebug/issues/363
Being able to set break points in a PHP script requires some kind of debugger extension being loaded, either XDebug or Zend Debugger.
And then you need some kind of interface to this debugger to make your wishes about break points known. I am unfamiliar with the Perl debugging, but I haven't heard about any PHP CLI based debugging - it is always taking place in an IDE that is able to handle the debugging protocol of one of the extensions.
Of course there is the good old var_dump();die('hi'); debugging, but this does not include continuing code execution after the script ended. ;)

sublime text 2 php tidy

I installed the phptidy plugin for Sublime Text 2 and tried to use it to clean up some ugly code like
$tdt="<td class=\"tit2\" ";
$linka='<a href="products.php?action=history5&item=';
while ($row=mysql_fetch_array($r))
{ extract($row);
But after running Php Tidy, a console flashed and it seems to have edited the entire file, but nothing actually changed. Does anyone know if the plugin below still works?
https://github.com/welovewordpress/SublimePhpTidy
I ran into the same problem. Console would open and close too fast to read what was going on.
Step 1: I opened up the Sublime Console (CTRL + ` on Windows)
Step 2: Reading the output gave me the hint. PhpTidy relies on php.exe being installed on your machine (duh)
This last step might seem obvious, but I was networked into another computer where the code lived and coding it over the wire. As such, when I ran phpTidy on my local machine, it failed due to the lack of php itself.
At first you must add the <?php ?> to beginning and end of your PHP file.
If you based-on Win, see the output of PHPTidy Processes on the 'Ctrl+`' Console.
There is a tip:
PhpTidy: calling php.exe -v returned: 0.
If it returns 1, maybe 'php.exe' wasn't found, add the path of your ‘php.exe’ to ENV.

php exec with vboxmanage to start virtual server.

I am trying to do a simple project to start a VirtualBox VM using a PHP script. My server is win 7 ultimate and running php5.3 I am using the vboxmanage.exe to start the server. cmd works great in a batch file or typed right into cmd line.
When I use:
exec("path to vboxmange.exe" startvm "vm name");
it doesnt work. If I change the code to:
exec(dir);
it works fine. I did some searching and everyone seemed to mention permissions for IIS_IUSRS. I set it to have read and execute on the vboxmanage.exe and tried to do it for cmd.exe but cant seem to get it to allow me to do this, though it doesnt seem necessary as it can run other cmds like dir.
another theory I have is that exec wraps the entire cmd in "" and this doesnt work when I try to type it in to cmd line manually. I have tried to trim it off but that doesnt work cause exec adds it on so nothing I do before can stop this.
any suggestions for another way to do this or what it might be?
From exec in the PHP Manual:
Note: When safe mode is enabled, you can only execute files within the
safe_mode_exec_dir. For practical reasons, it is currently not allowed
to have .. components in the path to the executable.
Check the value of your safe_mode_exec_dir in your php.ini. I would guess that it would be fairly restrictive by default.
If that doesn't work, take a look in the comments. Particularly, this comment might be of help to you.

PHP: trace script process flow

Is it possible within a PHP script to start a trace log and activate a debugging log.
I am not looking for eclipse + xdebug, but something like this use-case:
When script starts, it checks if $_GET["debugme"] is set. If yes, say start_trace_log().
Anything that happens after that in the rest of the script, should be logged, e.g.
scriptA.php :10 include("anotherscript.php")
anotherscript.php:1 foo()
...
At the moment, I have to manually do this for any script that i am interested to log and everywhere the script has to check $_GET["debugme"] instead of simply debugging ALL within this script run. Very uncomfortable for ocassionally checking scripts.
Any better ideas or comfortable ways of tracing php scripts from a start point to the last line?
Add this line to the end of the end or footer script:
if(isset($_GET["debugme"]))debug_print_backtrace();
that will print details like #... function-name() called at script-path.php:linenumber.
Don't forget to estrict the debugme feature to run on development system only!
phptrace may be a better choice cause you needn't to change your script and you can trace at anytime you want.
Although I find it highly annoying when this is used in production, you can throw this bit of code:
if(isset($_GET['DEBUGME'])) {
start_trace_log();
}
Into a file, and then adding that file to your PHP auto_prepend_file so it gets run at the start of every PHP script.
Of course, this is assuming that you've already coded and included start_trace_log(). You should also only include this on a development server. Scripts with debug flags shouldn't make it to production.

problem with xdebug vim plugin

I am using xdebug plugin for vim. After making few changes i was able to run debugger but not able to set breakpoints.
So, I enabled xdebug.remote_log and below is the log statements corresponding to setting breakpoint.
<- breakpoint_set -i 5 -t line -f file:///C:\htdocs\testLocal.php -n 36
->
Its issuing request to debugger in proper format only but no idea why debugger is returning "command is not avilable".
Please let me know if anything is wrong.
Make sure you set breakpoints on lines that contain a php expression, not on blank lines or lines containing just a closing bracket.
Setting breakpoints on blank lines doesn't work, and returns the cryptic 'command not found' error you are getting.
I had the same problem. When I checked the xdebug logs, it showed file:///http://myapp.local
As you see my ide (PHP eclipse) seems to insert the extra "http://" treating this as a URL instead of a file.
Luckily, this was the case with just my index.php. Other file breakpoints were being communicated correctly to xdebug and I was able to set and hit breakpoints on php expression as long as they didn't know span multiple lines. The latter for some reason would cause breakpoints to not hit and just pass by.
Hope this helps!
I spotted an extra "/" in "file:///C:\htdocs\testLocal.php", mayby the vim plugin isn't compatible with windows filepaths?
I recently just installed this same thing and found a tutorial by Blake Johnson all about installing and using Xdebug from within Vim.
Also, try clearing any cookies on the page you might have. This often times would cause the plugin to get screwed up in a strange way.
