By
The Xdebug extension encourages you to troubleshoot your content by giving a great deal of profitable investigate data.

Installing Xdebug for XAMPP with PHP 7.x

Basic Requirements


  1. XAMPP for Windows: https://www.apachefriends.org/download.html
  2. The VC14 builds require to have the Visual C++ Redistributable for Visual Studio 2015 x86 or x64 installed
  3. The VC15 builds require to have the Visual C++ Redistributable for Visual Studio 2017 x64 or x86 installed

Setup

Download Xdebug for:

  1. PHP 7.0.x: https://xdebug.org/files/php_xdebug-2.5.5-7.0-vc14.dll
  2. PHP 7.1.x: https://xdebug.org/files/php_xdebug-2.5.5-7.1-vc14.dll
  3. PHP 7.2.x: https://xdebug.org/files/php_xdebug-2.6.0-7.2-vc15.dll
  4. Copy the file php_xdebug-2.6.0-7.2-vc15.dll to C:\xampp\php\ext
  5. Open the file C:\xampp\php\php.ini with Notepad++
  6. Disable output buffering: output_buffering = Off
  7. Scroll down to the [XDebug] section (or create it) and copy this lines

 
[XDebug]
zend_extension = "c:\xampp\php\ext\php_xdebug-2.6.0-7.2-vc15.dll"
xdebug.remote_autostart = 1
xdebug.profiler_append = 0
xdebug.profiler_enable = 0
xdebug.profiler_enable_trigger = 0
xdebug.profiler_output_dir = "c:\xampp\tmp"
;xdebug.profiler_output_name = "cachegrind.out.%t-%s"
xdebug.remote_enable = 1
xdebug.remote_handler = "dbgp"
xdebug.remote_host = "127.0.0.1"
xdebug.remote_log = "c:\xampp\tmp\xdebug.txt"
xdebug.remote_port = 9000
xdebug.trace_output_dir = "c:\xampp\tmp"
;36000 = 10h
xdebug.remote_cookie_expire_time = 36000

     9. Restart the Apache (Stop/Start)

Now, if you run the phpinfo(); you can see the xdebug extension is enabled

phpinfo

By default Xdebug profile log name as cachegrind.out  You can add extra parameters to make dynamic. For myself, I added %t-%s which formats are

SpecifierMeaningExample FormatExample Filename
%ccrc32 of the current working directorycachegrind.out.%ccachegrind.out.1258863198.xt
%ppidcachegrind.out.%pcachegrind.out.5174.xt
%rrandom numbercachegrind.out.%rcachegrind.out.072db0.xt
%sscript name 2cachegrind.out.%scachegrind.out._home_httpd_html_test_xdebug_test_php
%ttimestamp (seconds)cachegrind.out.%tcachegrind.out.1179434742.xt
%utimestamp (microseconds)cachegrind.out.%ucachegrind.out.1179434749_642382.xt
%H$_SERVER['HTTP_HOST']cachegrind.out.%Hcachegrind.out.kossu.xt
%R$_SERVER['REQUEST_URI']cachegrind.out.%Rcachegrind.out._test_xdebug_test_php_var=1_var2=2.xt
%U$_SERVER['UNIQUE_ID'] 3cachegrind.out.%Ucachegrind.out.TRX4n38AAAEAAB9gBFkAAAAB.xt
%Ssession_id (from $_COOKIE if set)cachegrind.out.%Scachegrind.out.c70c1ec2375af58f74b390bbdd2a679d.xt
%%literal %cachegrind.out.%%cachegrind.out.%%.xt

Here %s is used for modifying only xdebug.profiler_output_name and not for xdebug.trace_output_name. 

And If you want to get the current profiling log file. you can call the function
xdebug_get_profiler_filename(), which returns the file name as a string


if you enable the xdebug.profiler_enable. it will run every single script. It will run all the time. So instead of that enable the xdebug.profiler_enable_trigger, the benefit of using profiler_enable_trigger you can enable and disable profiling by just pass the special GET or POST parameter XDEBUG_PROFILE to a PHP script. It will turn on profiling just for the one PHP script that receives the parameter. You need not set a value for XDEBUG_PROFILE, it is sufficient to append the parameter to the URL: yourUrl.php?XDEBUG_PROFILE.

Data Types in Python

By
Data Types  In C# or Java, You need to declare a variable specify them integer, string, and decimal. But in Python no need to specify. We can declare variables like Example: C# or Java int age = 28; string Name = "Siddhu"; Example: Python age = 28 Name = "Siddhu" So, you don't need to declare variable types in python. This is an advantage in Python, But still have few Disadvantages too. Example: In my Python function def add_numbers(x,y): print(x+y) add_numbers(20,50) //Output: 70 add_numbers(20,"Something") //Error:"Traceback (most recent call last): File "C:/Users/siddhartha.e/PycharmProjects/siddhu-py/my1stpycode.py", line 8, in add_numbers(50,"Something") File "C:/Users/siddhartha.e/PycharmProjects/siddhu-py/my1stpycode.py", line 4, in add_numbers print(a + b) TypeError: unsupported operand type(s) for +: 'int' and 'str'" ...

React JS Commands and Useful purposes  To Install react app: npx create-react-app app-name To Install react app: npx create-react-app . To check npm version: npm --version Inside that directory, you can run several commands:   npm start     Starts the development server.   npm run build     Bundles the app into static files for production.   npm test     Starts the test runner.   npm run eject     Removes this tool and copies build dependencies, configuration files     and scripts into the app directory. If you do this, you can’t go back! node -v (To check node version) The latest recommended command to create a new React app is: npx create-react-app@latest my-app Replace my-app with your desired project name. This approach uses the latest version of Create React App and works if Node.js (version 14+) and npm (version 5.2+) are installed Modern Alternatives If you prefer a faster, lighter setup, many developers n...
