Can't debug php with VS Code - php

I'm trying to debug my php with wamp, xdebug and this extension, but I can't get it to work. This is the end of my php.ini (C:\wamp64\bin\php\php7.0.4\php.ini):
[Xdebug]
zend_extension ="C:/wamp64/bin/php/php7.0.4/ext/php_xdebug-2.4.1-7.0-vc14-x86_64.dll"
xdebug.remote_enable=1
xdebug.profiler_enable=1
xdebug.profiler_output_dir ="c:/wamp64/tmp"
My launch.json (C:\wamp64\www\CubePicker.vscode\launch.json):
{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9000
},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9000
}
]
}
Settings.json:
// Place your settings in this file to overwrite the default settings
{
"emmet.syntaxProfiles":
{
"php": "html"
},
"php.validate.executablePath": "C:/wamp64/bin/php/php7.0.4/php.exe",
}
Can anyone see what I am doing wrong? I launch the debugger in VS Code, then run the webpage through my browser, which I assume is correct...? How can I fix this and make it hit the breakpoints I put in?
Let me know if you need anything else.
Thanks!
[EDIT]: I have been into phpinfo(), found the path of the loaded php.ini, and edited it to add the first chunk of code. This didn't fix the problem.
[EDIT]: I have also copied the whole of my phpinfo() here: http://pastebin.com/4Jk5TuQj

Author of the extension here.
As stated in the readme, you need to add
xdebug.remote_autostart = 1
to your php.ini so XDebug will actually make a request to VS Code.
I also searched your phpinfo() output but there was no XDebug section.
You should use the XDebug config wizard here: xdebug.org/wizard.php

Listen for XDebug php in vscode with xampp

Once I performed all the configuration stuff, downliading the .dll, adding it to the ext path in xamp and to the php.ini etc.
[XDebug]
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_port = 9003
zend_extension="C:\xampp\php\ext\php_xdebug.dll"
After adding both configs in vsCode:
1.- Installing the php debug extension
2.- Run->AddConfiguration->Listen for Xdebug
3.- Run->AddConfiguration->"Launch currently open script"
So both debug modes seem to be possible:
Surprisingly I can make the debug work if I "Launch currently open script".
De default config for the "Launch currently open script" is:
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 0,
"runtimeArgs": [
"-dxdebug.start_with_request=yes"
],
"env": {
"XDEBUG_MODE": "debug,develop",
"XDEBUG_CONFIG": "client_port=${port}"
},
}
But that did not work until I added runtimeExecutable":"C:\\xampp\\php\\php.exe.
For the case 1.- Listen for Xdebug, that is to debug the whole app without the need of selecting an specific file, I could not make it work. The launch.json is:
{
"name": "Listen for Xdebug",
"type": "php",
"request": "launch",
"port": 9003
}
I tried of course adding the runtimeExecutable":"C:\\xampp\\php\\php.exe, changing the ports, restarting apache and vs code and adding to de vs code settings the Allow Breakpoints Everywhere checkbox.
I am close, because for Launch current script mode works but when I launch vscode with the Listen for Xdebug option, my breakpoints are in place and my page is reloaded for check. Nothing happens and there are no errors in the vscode debug console.
Any idea of what needs to be done for the Listen for Xdebug to work and be able to debug the whole proyect with vscode?
Edit:
I also tried adding this options to my php.ini:
xdebug.mode = debug
xdebug.discover_client_host = 1
xdebug.start_with_request = yes
as recommended here
and the visualStudio php configuration Listen for XDebug 2 (Legacy)
Followed the intructions from the extension docs and I dont find what is wrong.

PHP Xdebug Doesn't work in VSCode - Windows + IIS

I have a problem with PHP Xdebug on VSCode.
My environment is Windows Server 2012 R2, I have installed VSCode and running IIS server with PHP 7.4, with Xdebug 3
When I open script with xdebug_info() from Firefox, then Xdebug log produces output. But when I hit F5 in VSCode there's no output (seems like extension doesn't connect with Xdebug at all).
VSCode config (it's default):
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Listen for Xdebug",
"type": "php",
"request": "launch",
"port": 9003,
"log": true,
},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9003,
}
]
}
php.ini:
[XDebug]
zend_extension = "c:\Program Files\PHP\v7.4\ext\php_xdebug-3.0.4-7.4-vc15-nts-x86_64.dll"
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_host=::1
xdebug.log = "c:\inetpub\xdebug_log.log"
VSCode debug output:
<- launchResponse
Response {
seq: 0,
type: 'response',
request_seq: 2,
command: 'launch',
success: true
}
But I don't see any variable's values at all. Breakpoints doesn't work too.
When I try to call something in debug console, the output is:
Cannot evaluate code without a connection
Which could be inferred from no-log entries produced by VSCode requests. I spent about 4 hours about googling this problem, but couldn't find solution.

Given this setting in my vscode

and xdebug.ini
zend_extension=xdebug.so
xdebug.mode=debug
xdebug.client_port=9003
xdebug.discover_client_host=1
This xdebug configuration is located in /etc/php/8.0/mods-available/ in WSL2 Ubuntu-20.04
following the setting here
https://github.com/felixfbecker/vscode-php-debug
But adding break point on php code and pressing f5, and visit the local php project in chrome
just nothing happen.
I did also read the following
Setting up VSCode with xdebug: pathMapping
VSCode - XDebug connected to client but break points does not work
but seems doesn't work to my case.
Do you know why?
previously its fine but now it's not
Just found an answer myself. On VSCode click the remote explorer not sure if this is really part of it and next install PHP debugger extension on Google Chrome.
Put a break point on PHP file, click PHP debugger on chrome, press f5 on VSCode, and it worked.
Edit:
My initial statement works, but not really the answer.
The actual answer is the https://github.com/felixfbecker/vscode-php-debug only support port:9000 or it's just xdebug the only support port 9000.
So instead of
xdebug.client_port=9003
Set it as
xdebug.client_port=9000

XDebug not working in VScode for php debugging

PHP debugging in vscode using xdebug and xampp is not working even after all configurations.
here is my php.ini file config:
zend_extension = D:\Xampp\php\ext\php_xdebug-3.0.0-7.3-vc15-x86_64.dll
[XDebug]
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
this is json file
{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9000
},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}"
}
]
}
xDebug 3 has changed several default values, so be sure your code is ready to work with new ones.
Here is my configuration set, which allowed me to use PHP breakpoints as always:
.vscode\launch.json
{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for Xdebug",
"type": "php",
"request": "launch",
"port": 9000
},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9000
}
]
}
php.ini (lines manually inserted in the end of a file)
[xdebug]
zend_extension = "php_xdebug-3.0.4.dll"
xdebug.mode = debug
xdebug.discover_client_host = 1
xdebug.start_with_request = yes
xdebug.client_port = 9000
Note: above zend_extension option would try to find your xdebug library in a .../modules/php/PHP_%your_php_version%/ext/ folder
I just got satisfaction with XDebug 3.
I found a good response here :https://github.com/felixfbecker/vscode-php-debug/issues/411 by jason-nabooki.
I do the same :
Json file :
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9003,
"stopOnEntry": true,
"log": true,
"pathMappings": {"/var/wwww/ammac":"${workspaceRoot}"}
},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9003
PHP.ini :
xdebug.mode= debug
xdebug.start_with_request = yes
xdebug.discover_client_host = true
To use the debugger (I didn't find immediatly due to my precedent use of Eclipse !),
first : click on the green triangle near "Listen for XDebug
second : refresh the web page in Firefox (or other)
For me it works i got the variables. Not yet test the breakpoints.
Remark : no need of the XDEbug helper in Firefox (surprise!)
In VSCode, I went to Settings -> Features -> Debug -> Allow Breakpoints Everywhere.
I check marked "Allow Breakpoints Everywhere" and I was able to debug again.
Struggled with this myself. Apparently XDebug 3.x doesn't work as outlined above. I found that even the equates under [XDebug] are no longer compatible. Download XDebug 2.x (I think 2.98 is the latest in the 2.x series). After I switched to 2.x, I'm no longer having any issue (so far).
https://xdebug.org/wizard - This tool helped me to find the reason why debuger didn't work.
Your are using xdebug version 3:
zend_extension = ... php_xdebug-3....
but in configuration you listen port 9000:
"port": 9000
The default Xdebug port changed between Xdebug v2 to v3 from 9000 to 9003.
Just change "port": 9000 => "port": 9003

Visual Studio Code - Xdebug won't work

In Visual Studio Code (1.9.1) (mac) i have setup the php-debug plugin.
In the debug screen i start 'listen for Xdebug'.
After this i open the index.php on my XAMPP server (local).
But nothing happens.
the blue bar at the bottom of the screen turns orange.
the step over, step into and step out buttons are greyed out.
Also the following error message occurs at the watched variables:
cannot evaluate code without an connection
I try to use breakpoints on the following code:
<?php
$i = 0;
do {
$i++;
if (!($i % 1)) {
echo('<p>$i = ' . $i . '</p>');
}
}
while ($i < 100);
?>
I am using XAMPP and in my php.ini file i use port 9000 for Xdebug.
zend_extension="/usr/local/Cellar/php71-xdebug/2.5.0/xdebug.so"
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote.port=9000
I installed Xdebug using homebrew.
Here is my php info:
phpinfo.htm
Xdebug wizard tells me Xdebug is installed correctly.
my launch.json file looks like this:
{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9000,
"log": true
},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9000
}
]
}
Would anyone know what i am doing wrong?
After setting the xdebug.remote_connect_back = 1 in the ini file
as n00dl3 suggested debugging most of the time works, but once in a while i get the following
error in the debug console:
<- threadEvent
ThreadEvent {
seq: 0,
type: 'event',
event: 'thread',
body: { reason: 'exited', threadId: 1 } }
I encountered this problem as well, not with the same environment (NGINX server + php-fpm) but the same symptoms. It turned out to be caused by my xdebug configuration.
How I managed to diagnose it : by writing a simple PHP script for test just like OP did :
<?php
xdebug_info();
By browsing to it, I got a bunch of info on my setup, including :
xdebug.client_host => localhost
xdebug.client_port => 9003
whereas my xdebug was listening on port 9900 (default being 9000).
Steps to fix : just add the following lines to your php.ini or xdebug.ini (wherever the rest of your xdebug configuration lies) :
# This should match your xdebug.remote_host
xdebug.client_host=localhost
# This should match your xdebug.remote_port
xdebug.client_port=9900
xdebug.mode=debug
Then rerun a debug session in VScode, add some breakpoints, and re-browse to your script : my VScode window popped up, the execution was paused on the breakpoint and the variables where accessible in the debug pannel just like expected.
EDIT : don't forget to also :
add xdebug.mode=debug to your php.ini
restart webserver and php-fpm services.
It seemed the server root needed to be set
in the launch.json with localSourceRoot like this:
{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9000,
"log": true,
"localSourceRoot": "http://127.0.0.1/public_html/"
},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9000
}
]
}
Now breakpoints are working like they should.
In my case, these two lines were missing from the php.ini file.
xdebug.mode = debug
xdebug.start_with_request = yes
Check xdebug.client_port
in page xdebug_info(); or phpinfo();
Config same port in launch.json of vscode
I just had this problem too.
Somehow, someday, without realizing it, I got version 3 of xdebug installed, and a lot of conf param name changed , see this SO question
So verifying the xdebug version with phpinfo for example can be worth a shot.
I am working with VSCODE devcontainer and I fix with the config below:
My launch.json for VSCODE
{
"version": "0.2.0",
"configurations": [
{
"name": "Xdebug",
"type": "php",
"request": "launch",
"port": 9003
}
]
}
I use Dockerfile with a RUN below to install xdebug:
RUN pecl install xdebug && docker-php-ext-enable xdebug
I find my xdebug config file in /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
I edit the file as below:
zend_extension=xdebug
[xdebug]
xdebug.mode=debug
xdebug.client_host=host.docker.internal
xdebug.start_with_request=yes
xdebug.idekey=VSCODE
Or you can add it in Dockfile like below:
RUN echo ' \n[xdebug] \n\
xdebug.client_host=host.docker.internal \n\
xdebug.mode=debug \n\
xdebug.start_with_request=yes \n\
xdebug.idekey="VSCODE" \n\
\n' >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
mode This setting controls which Xdebug features are enabled. We’ve set develop to enable development aids, such as getting better error messages, and debug to enable step debugging.
client_host This setting tells Xdebug the IP address or hostname of the machine that is running your text editor or IDE.
start_with_request This setting determines whether a function trace, garbage collection statistics, profiling, or step debugging are activated at the start of a PHP request. Setting it to yes instructs Xdebug to always initiate a debugging session.
