Listen for xDebug Method

Call the following line of code on the first lines of your script. FB::setEnabled(false); What’s great about this is that you can leave all of your FirePHP code in your scripts for later use – just pass either true or false when you want to turn logging on or off.

Here are the steps to doing PHP programming:

1. Check for PHP extensions in VS Code.
2. Install the PHP Debug extension.
3. Click “reload” to reload VS Code.
4. Install Xdebug.
5. Now when you have the right version, put it in the PHP/ext directory.
6. Next, you need to configure PHP to use the extension and allow remote debugging.

But first, right-click any php-file->Open with… ->choose program, then select Firefox in the list. You must install a local web server like xamp, wamp or easyphp. Have a good time.

To debug the code, you first need to be able to navigate through your source code in the Dev Tools. You do this in the Debugger tab. The left pane of this tab has a tree view of all the source files loaded into the page. You can navigate these as you would in an IDE, as the contents are displayed in the central pane.

1. Open a .
2. Add some code and add some breakpoints.
3. Change the Debug select option to ‘Listen for xDebug’.
4. Press F5 to start the debugger.
5. Click the new XDebug Helper extension and click the Debug option.
6. You will notice that helper icon has turned turn green (See image below)

How PHP Debugging with XDebug Works in NetBeans IDE

1. Set a breakpoint at each line where PHP source code execution should pause.
2. Start a debugging session.
3. When a line with a breakpoint is reached, execute the script one line after another by pressing F7 and F8.
4. Close the debugging session.

In Visual Studio Code, select “File” and then “Open Folder” and choose the folder containing your PHP code. Choose the Debug View from the left hand side and then click the Debug button to configure our debugging environment. The first time the Debug button is selected it will create a debugging configuration file.

Firefox has never processed PHP code natively. You need to have server software running locally that processes the PHP code and that sends the resulting file as text/plain instead of application/x-httpd-php.

FirePHP Cross-Browser Devtools Extension for PHP Development

1. Mozilla Firefox (>= 56.0.2) Install Extension & open Developer Tools. Click on.
2. Google Chrome (>= 75) Install Extension & open Developer Tools. Click on.
3. Brave (>= 0.64) Install Extension & open Developer Tools. Click on.

In Mozilla version 37.0. 1 after open developer tool by click on console edit your java script code at right side of tool window and after finish editing click on run to test your java script code in browser.

Debug JavaScript

1. Step 1: Reproduce the bug.
2. Step 2: Get familiar with the Sources panel UI.
3. Step 3: Pause the code with a breakpoint.
4. Step 4: Step through the code.
5. Step 5: Set a line-of-code breakpoint.
6. Step 6: Check variable values. Method 1: The Scope pane. Method 2: Watch Expressions.
7. Step 7: Apply a fix.
8. Next steps.

The JavaScript Debugger enables you to step through JavaScript code and examine or modify its state to help track down bugs. You can use it to debug code running locally in Firefox or running remotely, for example on an Android device running Firefox for Android. See remote debugging to learn how to connect the debugger to a remote target.

Although this PHP debugging technique is basic, it is still in use. When you are working in the dev environment on any web hosting for PHP, error reporting must be on so that you can have a quick look in browser what error logs in PHP are generating. You can enable/disable error logs from the php.ini file and individual php files.

On Linux distribution like Debian, you can use Sudo to install Xdebug in PHP: Now, open the file etc/php/7.0/mods-available/xdebug.ini and add the following code to enable Xdebug: Now, restart the Apache2 server.

Xdebug is your saviour here. Basically, Xdebug is an extension of PHP which helps developers in debugging and smooth development of their projects to carefully watch for errors and solve them. It upgrades PHP’s var_dump() function. It also adds stack traces for Notices, Warnings, Errors and Exceptions.
