PHP Stands for Personal Home Page, its a Script Language and Interpreter that is freely available and use Primarily on Linux Web Servers. Oracle Corporation develops, distributes, and supports MySQL, the most popular open-source SQL database management system. If you are beginner in PHP and MySQL then this article will surly help you to clear some of your concepts to understand these two tools.


From the outset, PHP started as a simple scripting platform called “Personal Home Page.” These days PHP is an option of the Microsoft’s Active Server Pages (ASP) innovation.

Developers use PHP, an open-source server-side language, to create dynamic web pages. It very well inserted into HTML. Typically, developers use PHP in conjunction with a MySQL database on Linux/UNIX web servers. It is presumably the most famous scripting language. Developers widely use PHP as a general-purpose scripting language and interpreter, which is freely available. You can find a full explanation of all PHP functions, a comprehensive user manual, and plenty of tutorials on the official PHP page. A most significant aspect regarding utilizing PHP is to have a PHP specific host.


MySQL is a uninhibitedly accessible open source Relational Database Management System (RDBMS) that utilizations Structured Query Language (SQL). SQL is the most well-known language for including, getting to and overseeing content in a database. It is most noted for its speedy handling, demonstrated unwavering quality, straightforwardness and adaptability of utilization. MySQL is a fundamental piece of pretty much every open source PHP application. Genuine models for PHP and MySQL-based contents are WordPress, Joomla, Magento and Drupal. A most significant aspect regarding utilizing MySQL is to have a MySQL particular host.

PHP’s distinguishing feature is that it executes the scripting code on the server, generating HTML that it sends back to the client. The client receives the result of executing the script without knowing the underlying code. Developers can configure the web server to process all the HTML files (containing the PHP script).

PHP course is easy to learn for any newcomer, but also offers advanced programming features.

Using PHP with a Database System:

PHP, as a scripting language, is popular among web developers because of its ability to interact with database systems including Oracle and MySQL.

This article discusses the use of PHP scripting language with the MySQL database. Any website can require a variety of data or information to display and to retrieve them from the database. This can include display of a simple list to the running of the website based on data stored in the database.

Some examples where PHP and MySQL can be used together are listed below:

  • The PHP script retrieves a digital banner from the database, selects a random banner from its table records, and sends it back to the calling script for use in digital ad banners. The PHP script can also maintain a count of banner views and clicks from the website.
  • Internet forums or digital boards, which use PHP and MySQL to store and retrieve user messages.
  • In website designing, a couple of PHP scripts can change the design of an entire website, eliminating the need to change and upload each web page individually. The PHP script can access the MySQL database to retrieve all information about the web page.

Setting up the MySQL Database:

The procedure of setting up the MySQL database varies according to the host. Every database would require a user name and password, in order to access the database. Database administration can be done using PHP scripts or using a program like PHPMyAdmin.

The next step is to create the database tables for storing the website information. Creating a database table using PHPMyAdmin is also simple. Alternatively, one can create and configure the entire database using the following PHP script:

CREATE TABLE tablename {


}Where the Fields are coded as fieldname type(length) extra_info

Example: first varchar(15) NOT NULL

The following command is used in the PHP script to connect to the MySQL database:



  • localhost is the server address on which the web site is running,
  • $username is the user name for the database access
  • $password is the password for the database access

Executing PHP Commands:

After configuring and connecting to the MySQL database, you can start executing PHP commands on the server.

Following are the 2 methods of executing a PHP command:

  • Entering the command in PHP using the following syntax:


  • This form of command can be used to repeat the command simply by changing the variable.
  • Defining the command as a variable. The result of the operation will be assigned to the variable.

Data Input and Output:

Inserting data using PHP is identical to the procedure of data input using HTML pages. The advantage of using PHP is that the script does not need to be changed for each new piece of input data. Users can also input their own data on the web page.

Then again, you can utilize factors to enter data into the database. Model:


$query = “Addition INTO contacts VALUES

The HTML form can call the insert.php file, which saves this content. Using this technique, the website page structure stores entered data in defined variables, which then pass to PHP.

To show (or yield) the entered information utilizing PHP, you can utilize the accompanying MySQL direction with the outcome doled out to the variable.

$query=”SELECT * FROM contacts”;

PHP offers two submission methods, GET and POST, to retrieve the data submitted by the form into your PHP script. GET strategy shows the factors and the information in the page address, while they are undetectable in the POST technique. For instance, a content can be made that will show diverse pages relying upon the clicked connection.

yourpage.php?user=charles (to show Charles’s page)
yourpage.php?user=nathan (to show Nathan’s page)


At the point when joined together, talented PHP and MySQL engineers can manufacture extremely ground-breaking and adaptable Web/Internet/Intranet Applications. PHP and MySQL are alluded to as improvement apparatuses.

PHP and MySQL are Open Source, implying that they are free advancement apparatuses, and there is a huge network of devoted volunteer software engineers who add to make upgrades and are consistently adding highlights to it. The improvement instruments and database servers that require authorizing expenses have restricted programming assets contrasted with open source advancement apparatuses, which have a gigantic and quickly developing devoted and educated network that stretches out the world over.

There has been contradiction about which apparatus is better. Normally, the designer who has more familiarity with one tool over the other will prefer to use the tool they have experience with.

With our experience, we have discovered that, PHP and MySQL are the best improvement devices. When developed successfully, developers can build applications with clean and straightforward usability, complex functionality, speed, power, and flexibility.

Great Development Practices:

One thing to take note of: No issue how incredible the advancement apparatuses are that you are creating with, if the application isn’t grown effectively, the final product may not be advantageous.

PHP and MySQL are assembled so that anybody with a basic amount of programming knowledge can build a program-based web application. This simple section to PHP advancement can likewise make issues when an unpracticed developer takes on a huge Web Application venture and doesn’t think about security suggestions, versatility and the SQL execution time when there are huge simultaneous associations, just to begin.

Instances of muddled coding and messy SQL questions:

  • Not utilizing coding rules
  • Blending HTML in with PHP capacities
  • Coding irregularities
  • Utilizing various styles of capacity calls
  • Cluttered rationale
  • History and People that are behind PHP

The Zend Engine fuels the PHP scripting language, which is written in C. Rasmus Lerdorf initially created PHP in 1995, and later, Zeev Suraski and Andi Gutmans reworked it in 1997. Zeev Suraski and Andi Gutmans established Zend Technology and made the motor behind PHP, the Zend Engine. Suraski and Gutmans effectively engaged with taking PHP to its zenith achievement.

PHP Popularity:

PHP is one of the most well-known scripting dialects utilized in building dynamic destinations. It has arrived at its bleeding edge prevalence in 2009 utilized on in excess of 27,000,000 spaces.

What is Zend Engine?

Zend Engine is the PHP compiler and runtime motor. Zend Engine is liable for assembling the PHP Script into the Zend Opcode (Virtual Machine), at that point executing the opcodes and creating the outcomes into the Web Server.

The Zend Optimizer is a help that runs the records encoded by the Zend Encoder. The standard Zend run-time compiler utilized by PHP is for sure extremely quick, producing code that is typically 2 to multiple times quicker. In any case, an application that utilization Zend Optimizer can execute contents another 40% to 100% quicker. Zend Optimizer incorporated into the standard PHP circulation after PHP 5.3.

Zend Guard Compatibility: The encoded records incorporated with a good form of Zend Guard. At the point when you don’t know about the Zend Guard form, consistently utilize the most recent rendition of Zend Optimizer.
