Display Other Texts rather then English using PHP MySQL

When we want to display and store the data other than ENGLISH using PHP.

Below is the code used to save and retrieve the data in PHP.

mysql_set_charset('utf8',$db_connect);

where $db_connect is the "MySQL Host" connection handler. You can see the example below for the connection handler.


<?php
$db_connect = mysql_connect(HOST_NAME,USERNAME,PASSWORD);
mysql_set_charset('utf8',$db_connect);
?>

By using the above, we can store and retrieve the data in different languages like Telugu, French, Hindi, German and many.

Note: And also a major note we need to be keep in mind, when we try to retrieve the same UTF-8 converted data using AJAX. We should not use "mysql_set_charset" as AJAX by default sets the content as "UTF-8" 

Disable Back Button using Javascript

User tries to use back button for most of the applications and it is valid, but few of the cases is required to disable the back button and also restrict the user.

It would be very useful when the user is on payment page. Below is the code to disable the back button in Browser.

var currentURL = window.location.pathname + window.location.search;

 history.pushState(null, null, currentURL);

 window.addEventListener('popstate', function(event) {

  history.pushState(null, null, currentURL);

 });

It works in all major browsers
