Here you will learn how to develop PHP login form using My SQL database. what happens when you submit your credentials to any login form.

You will understand the login application how it actually works in real time here.

Many methods like mysql_real_escape_string(), mysql_query(), mysql_num_rows(), mysql_connect(), mysql_select_db(), mysql_close() were deprecated in PHP 5 and removed from the latest version of PHP i.e. It uses prepared statements and My SQL scripts to create a PHP login page with validations" data-medium-file="https://i2com/ SQL-scripts-to-create-a-PHP-login-page-with-validations.jpg?

Another common approach in Java Script-intensive web database applications is to write two sites: one that uses Internet Explorer Java Script and another that uses Netscape Navigator Java Script.Java Script isn't a fully fledged programming language like PHP: it can't connect to databases, it's limited as to which system resources it can interact with, and it can't do most tasks a web database application requires.However, Java Script is good for interacting with a ), changes in the browser appearance, and resizing of the browser.Example 7-7 shows how the browser application name and version can be detected with both Java Script and PHP.The output of the script rendered in a Netscape browser is shown in Figure 7-5.

These differences can be compounded by the fact that the web database application developer usually has little control over the standardization of the client Java Script environment.
