how to develop web application with php sql

PHP and MySQL are great for the creation of dynamic web pages and apps. They are currently some of the most extensively used technologies for creating back-end applications around the globe. They enable you to generate dynamic content and bring it to life on your website. They also enable data to be saved in the backend database and used in a variety of ways. You’ll eventually be able to apply what you’ve learned to create more complicated and powerful web pages and applications with PHP and SQL.

In the software development industry, PHP is not a programming technology that is questioned for its efficiency. It is the most widely used server-side scripting language. Even though PHP was released 25 years ago, it continues to grow in terms of popularity.

The combination of PHP SQL design has made it easier for organisations of all sizes to succeed. For their perfect results, PHP and SQL web development has become well-known among all software engineers.

Do you have any idea why PHP and SQL are merged?

PHP SQL, is open-source, meaning that anyone can use them for free on the internet. It employs a relational database management system. SQL can manage a huge number of database connections at the same time. When both of these technologies are integrated, they offer some of the most beneficial advantages to organizations looking to boost earnings with their web apps.

To be a successful businessperson, you must use reliable programming tools and database management systems. With millions of websites published each year, the web app market is flooded with traffic and competition. Businesses are looking for the best process on how to design web application with PHP SQL and a list of top PHP companies in India.

We’ll cover some of the concepts in this post, all of which can be utilized to build dynamic Web apps with PHP SQL solutions. External files can be included, custom functions can be written and used, emails can be sent, the Web browser can be redirected, and the date() function in PHP can be used. Some of the particular examples are based on prior chapters’ work, and the majority of the code in this chapter will be reused in some way or another in subsequent chapters.

Benefits of How to develop web application with PHP SQL

If you want to get the most out of your web application development services investment, this pair is a good option. Here are the PHP SQL benefits to create web database applications.

Security Assurance

Here are the steps to follow  – How to develop a web application with PHP SQL

Collecting essential requirement

Even the tiniest personalized initiatives must have parameters for what must be completed. Understand the issue, what the users want, and what has to be done in general.

  • We’ll need to make a quick to-do list.
  • The list of tasks should be kept in a database.
  • If a task is still “pending,” “completed,” or “cancelled,” flags should be displayed.
  • Create a page where you can manage your tasks

Create the database’s structure

Let’s move on to the project’s basis – the database tables – now that we’ve completed the planning and have a basic notion of the system.

This should be easy to understand:

  • todo_id”: The primary key is the task ID
  • todo_task: The task itself is described.
  • todo status: The task’s current status: 0 indicates that it is pending, 1 indicates that it has been completed, and 2 indicates that it has been cancelled.

Yes, that should be adequate to meet the “keep the activities and monitor their status” requirement.

PHP Library

  • The function Object() { [native code] } connects to the database when the $TODO = new ToDo() object is formed, and the destructor closes the connection when the object is destroyed.
  • query() is merely a helper function that does SQL queries.
  • There are only three key functions that cover “manage to-do items”!
  • Add or update a task with the save() function.
  • getAll() returns a list of all to-do items.
  • Delete a task with the del() function.

Client-side pages

The final step is to design a page to manage the to-do items now that the foundations have been laid (user interface).



require "2-todo-lib.php";

if (isset($_POST['action'])) {

  // (A1) SAVE TASK

  if ($_POST['action']=="save") {

    $pass = $TODO->save(

      $_POST['task'], $_POST['status'], (isset($_POST['id'])?$_POST['id']:null)




  else { $pass = $TODO->del($_POST['id']); }


  echo "<div class='notify'>";

  echo $pass ? "OK" : $TODO->error ;

  echo "</div>";




<form id="ninForm" method="post">

  <input type="hidden" name="action" value="del"/>

  <input type="hidden" name="id" id="ninID"/>


<div id="tasks">

  <!-- (C) ADD NEW TASK -->

  <form method="post">

    <input type="hidden" name="action" value="save"/>

    <input type="text" id="taskadd" name="task" placeholder="Task" required/>

    <select name="status">

      <option value="0">Pending</option>

      <option value="1">Done</option>

      <option value="2">Canceled</option>


    <input type="submit" value="Add"/>


  <!-- (D) LIST TASKS -->


  $tasks = $TODO->getAll();

  if (count($tasks)!=0) { foreach ($tasks as $t) { ?>

    <form method="post">

      <input type="button" value="X" onclick="deltask(<?=$t['todo_id']?>)"/>

      <input type="hidden" name="action" value="save"/>

      <input type="hidden" name="id" value="<?=$t['todo_id']?>"/>

      <input type="text" name="task" placeholder="Task" value="<?=$t['todo_task']?>"/>

      <select name="status">

        <option value="0"<?=$t['todo_status']==0?" selected":""?>>Pending</option>

        <option value="1"<?=$t['todo_status']==1?" selected":""?>>Done</option>

        <option value="2"<?=$t['todo_status']==2?" selected":""?>>Canceled</option>


      <input type="submit" value="Save"/>


  <?php }} ?>

</div>Take some time to read through the above – we’re simply utilising the library to build the necessary HTML list. We’ve combined the HTML forms and PHP processing into a single page for simplicity’s sake.

However, we will normally break the processing into a separate “PHP AJAX handler script”; it is better to maintain this as a “pure interface page,” as it will be much easier to update when users say “this does not look nice” to a technical code ninja with no design experience.

Last but not least, software development never truly stops. For instance, in the future, we may want to improve the to-do list:

  • Add a timestamp to the task to keep track of when it was last updated.
  • Add a new column to the database called “updated.”
  • Update the functions in the PHP library to include a timestamp as well.
  • The timestamp should be displayed somewhere on the to-do list.

Yes, you’re upgrading the development cycle; it never stops and will keep looping as new requirements arise.


PHP SQL web development is the best choice if you want dynamic, scalable, and high-performing web projects. Furthermore, because both are open-source, this combination allows for cost-effective development.
