JavaScript to Disable Mouse Right Click ,Cut, Copy and Paste Options

If we want to prevent the user from copying content from a web page,
we need to disable right click and also we need to disable the copy, cut,
paste options.

<!DOCTYPE html>

<html lang="en">


    <script src=""></script>

    <!--Javascript code for disable right click-->

                return false;

    <!--Javascript code for disable cut,copy,paste-->

            $(document).on("cut copy paste",function(e){
                return false;



1. contextmenu (also called contextual, shortcut, and pop up or pop-up menu) is a menu in a graphical user interface (GUI) that appears upon user interaction, such as a right-click mouse operation.

2. The on( ) method attaches one or more event handlers for the selected elements and child elements like cut, copy, paste.

Kahlan is a full-featured BDD testing framework that makes it possible to write Unit Tests using the describe-itsyntax. It embraces the KISS (Keep It Simple, Stupid) design principle. Kahlan requires at least PHP 5.5.

PHP Debugging Tools


Pinba is an open source MySQL storage engine that acts as a statistics server for PHP. It uses the data received to analyze the performance of PHP apps and locate any problems quickly.

PHP_Debug is an open-source project that gives you useful information about your PHP code that can be used for debugging. It can output processing times of your PHP and SQL, check the performance of particular code blocks and get variable dumps in graphical form, which is great if you need a more visual output than the one given to you by print_r() or var_dump().

DBG is a robust and popular PHP debugger for use in local and remote PHP debugging. It plugs into numerous PHP IDE’s and can easily be used with the command line.

Webgrind is a Xdebug profiling web frontend in PHP5. It implements a subset of the features of kcachegrind and installs in seconds and works on all platforms. For quick N dirty optimizations, it does the job

PHPMD is an easy to configure, user-friendly front-end for the raw metrics that PHP Depend measures. It looks for several potential problems in your code, including possible bugs, suboptimal code, unused parameters, and more.

Xdebug is one of the most popular debugging PHP extensions. It provides a ton of useful data to help you quickly find bugs in your source code. Xdebug plugs right into many of the most popular PHP applications, such as PHPEclipse and phpDesigner.

Gubed PHP Debugger
As the name implies, Gubed PHP Debugger is a PHP debugging tool for hunting down logic errors.

PHP_Dyn is another excellent PHP debugging tool that’s open-source. You can trace execution and get an output of the argument and return values of your functions.

MacGDBp is a live PHP debugger application for the Mac OS. It has all the features you’d expect from a fully featured debugger, such as the ability to step through your code and set breakpoints.

When debugging PHP code, var_dump(), print_r() and debug_backtrace()are usually our best friends. Kint, an open source resource, is a zero-setup replacement that offers a better debugging experience. It smartly detects the type of data being dumped displays tailored alternatives to otherwise hardly readable data. The name of the variable, file, its line and the function wrapping it are all presented.

DebugBar is a free and open source app that can integrate into any PHP project and collect + present profiling data. It has no dependencies, supports Ajax requests and includes generic data collectors and collectors for well-known libraries. The bar is 100% JavaScript that sits in the footer (like Dev. Tools). New collectors and views can be added with ease and it is possible to save/re-run previous requests.

Whoops is a PHP library for handling errors and debugging them much easier. The library provides stack-based error handling with a good-looking error interface. It has a simple API for dealing with exceptions, trace frames + their data and can integrate with any framework (ready-to-use integrations exist for the end and Silex).

Many PHP developers use print_r() & var_dump() for debugging which output hard to read/unformatted results. Krumo is a replacement for these functions which can display structured information about any PHP variable. Once Krumo is running, the output is displayed in a collapsible DHTML tree built around the structure of the dumped PHP variable. Also, it speeds up the debugging process by the ability to turn it “off” rather than disabling every dumping route inside the code.

Delete files from folder using php

Sometimes we need to free the space of the web server by deleting old or specific or all files from a directory. Means we want to remove files from the folder without know the name of the files. This type of functionality required for the following situation.
1. Need to remove all files in a folder for free the space of web server.
2. Need to remove old files in a folder which are used before the specific time.
3. Need to remove some files from a folder which holds a specific extension.

To delete files from directory we’ll use glob() and unlink() functions in PHP.
glob() function is used to get filenames or directories as an array based on the specified pattern.
unlink() function is used to delete a file.
Delete All Files from Folder:
The following script removes all files from the folder.
$files = glob('NewFolder/*'); //get all file names
// NewFolder is the name of folder
foreach($files as $file){   
unlink($file); //delete file
Delete Specific Type of file  from Folder:
The following script removes only those files which have a specific extension.(In this example delete all file with .jpg extension )
$files = glob('NewFolder/*.jpg'); //get all file names
// NewFolder is name of folder
foreach($files as $file){   
unlink($file); //delete file
Delete Old Files from Folder:
The following script removes the files which modified before the specified time.
$files = glob('NewFolder/*'); //get all file names
// NewFolder is the name of folder
foreach($files as $file) {    
$lastModifiedTime = filemtime($file);    
$currentTime = time();    
$timeDiff = abs( $currentTime - $lastModifiedTime) / (60 * 60); //in one hours   
 if (is_file($file) &&  $timeDiff > 10) //check if file is modified before 10 hours     
 unlink($file); //delete file
