These PHP application programming interfaces (APIs) are being used to connect with MySQL databases and tables. Both of these options are available to engineers to employ for their projects; however, MySQLi is not compatible with PHP 7 or later versions. Meanwhile, the programmer may use MySQLi with PHP 5, although PHP 5 is no longer supported.

MySQL and its successor, MySQLi, are both Relational Database Management Systems. To refresh your memory, a Relational Database Management System is designed after entities that reflect connections in the actual world. The information is kept in a tabular format for storage, normalized and constrained, so it may be linked to other data.

The MySQLi Extension is packed with a wide variety of features that supplement and enhance those made available by MySQL, which is MySQL's predecessor. Some stand out from the crowd more than the rest. An object-oriented interface, support for statements that have been previously prepared, support for a variety of reports, support for any kind of transaction that takes place, support for an enhanced level of debugging support, and support for an improved level of server support that is already embedded in the infrastructure of the database are some of these features that are meant to enhance the functionality of the MySQL (as well as provide an update to the database manager as a whole). Other features include: support for any kind of transaction that takes place, support for any kind

My SQL vs. My SQLi

The main difference between MySQL and MySQLi is. MySQL is an older database driver, whereas MySQLi is a newer, improved version of that driver.

Relational Database Management Systems, or RDMS for short. MySQL and its fork, MySQLi, are examples of relational database management systems. As you may already be aware, the foundation of a relational database management system is made up of objects that stand in for actual relationships in the real world. This data is handled in the form of a table, and through normalization and constraints, it has been connected to a large amount of additional information. PHP is the programming language that uses the MySQLi Extension, a relational database driver also known as MySQL Improved or MySQLi. MySQLi Extension may also be referred to by its shorter name. It offers a user interface to the MySQL databases that have previously been established. It is a better version of its predecessor, MySQL, which was only a mechanism to administer databases between servers. MySQL's primary purpose was to facilitate the transfer of data.

One of the benefits of using MySQLi is that it comes with object-oriented support for the MySQL database that it is built on top of. This makes it easier for programmers to create connection objects and carry out their responsibilities using the methods provided by the kind of link object being used. On the other hand, MySQL performs just as well as MySQLi in applications where the database queries are only CRUD operations.

As the database component of a solution bundle, sometimes known as a LAMP software stack, MySQL may be found in a wide variety of online applications. Its application may be observed on a large scale on several well-known websites, like Flickr, Facebook, Wikipedia, Google, Nokia, and YouTube, among others. Every one of these websites uses MySQL as its data storage and logging system for user information. The source code is written in C and C++ and runs on various operating systems and platforms, including Linux, Mac OS X, and Microsoft Windows.

Regarding security, MySQLi has a mechanism that protects against SQL Injection attacks already set up and ready to go. Additionally, MySQLi supports most of MySQL's features, providing the added convenience of APIs. Because of its application programming interfaces (APIs), MySQLi does have the edge over MySQL. When dealing with duplicate tasks, developers typically find that using APIs rather than developing their queries is a more efficient. In addition, PHP developers are strongly urged to use MySQLi rather than MySQL due to the superior language compatibility and community support that MySQLi offers.

What is MYSQL?

These are the most important extensions that would be used to let Application code communicate and receive information with MySQL databases. On the other hand, MySQL is no longer supported in PHP 7 and later versions, and its functionality has been deprecated.

MySQL is a database management system that is both open-source and available at no cost. This data management system is by far the most popular option now available on the market. Examples of this include Facebook, Twitter, YouTube, and various other well-known apps. It requires a procedure that is broken down into steps. In addition to being free and open-source software distributed under the GNU General Public License terms, MySQL is also made available immediately below several other commercial licenses.

A database is more than a collection of data organized in a certain way. Consider the process of taking a selfie, in which you press a button to take a picture of yourself. Your picture is a piece of data, and the gallery app on your phone is the database. A database is a location that stores data and organizes it in a structured manner. When you hear the phrase "relational," it indicates that the information saved in the dataset is laid out in tables. Each table is connected to the others in some manner. Refer to the program as a database management system if it does not support the relational data model.

MySQL was first conceived and financed by a Swedish company, MySQL AB, which was subsequently acquired by Sun Microsystems (now Oracle Corporation). After Oracle purchased Sun in 2010, Widenius divided the open-source MySQL project into what would later become MariaDB. Dual-licensing is implemented in the MySQL web server and the client libraries of the MySQL database management system. They may be obtained either under the GNU General Public License version 2 or under a private license.

The official guidebook is a resource that may be of use. In addition, assistance may be obtained for free via several IRC channels and newsgroups. Oracle's MySQL Enterprise solutions offer premium support. These vary in the scope of services provided and the prices. In addition, several groups are independent of the government that provides aid and assistance.

What is MySQLi?

There is a relational database driver known as MySQLi, which provides access to MySQL databases. Improved is represented by the letter I in the MySQLi programming language. The majority of its applications are found in PHP coding. The solution of problems is done in an object-oriented fashion using this method. The MySQLi extension was first made available in PHP version 5.0.0, while the MySQL Native Driver was made available in PHP version 5.3.0.

MySQLi, which stands for improved, provides users with various options for gaining access to the MySQL database and modifying the individual data items it contains. The MySQLi functions would have to be invoked like any other PHP function would need to be called. This study is intended for Java programmers who want a more in-depth understanding of how to link PHP MySQLi techniques to MySQL and is built specifically for them.

Accessing MySQL databases may now be done more efficiently with PHP thanks to the MySQLi extension, which has an I that stands for "enhanced." Oracle and Microsoft SQL Server are two of the world's most widely used relational database management systems (DBMS). MySQL is also among the most commonly used of these systems. Relational databases are an essential component of the internet because they make it feasible to handle and store vast volumes of data throughout an extended period. This entails breaking down large data sets into smaller subgroups and putting those subsets in the proper relation to one another depending on the circumstances.

There are three distinct entry points available for using MySQL as a database. The earliest one still uses the MySQL extension, which was marked as obsolete starting with PHP 5.5 and eliminated beginning with PHP 7. In PHP 7, the MySQL() function is deprecated and will not operate. MySQLi has taken its position as the new system ().

MySQL databases may be accessed with PHP via several different extensions, one of which is the PHP Data Objects (PDO) extension, which is notable for the flexibility with which it can be put to use. The older MySQL extension is still available. The MySQL Improved Extension is used in the third method. Since PHP version 5, it has been possible to connect to MySQL databases by using an extension called mysqli. The following line of code may be an example of PHP MySQLi.

The Swedish business MySQL AB first developed this software in 1994; however, the Oracle Corporation is currently responsible for its distribution and uses a dual licensing structure. Oracle provides not just its private Enterprise Edition but also an open-source version licensed under the GNU Public License. Because of this dual licensing, businesses can create their applications based on MySQL without worrying about violating license agreements.

Before beginning this course, students must have a strong understanding of the programming language PHP. Since you'll be dealing with MySQL databases, you should have a solid knowledge of SQL and the fundamentals of databases.

Main Differences Between MySQL and MySQLi in Points

  • MySQL comes complete with its command-line user interface. MySQLi, on the other hand, connects to MySQL databases using a graphical user interface.
  • SQL Injection attacks have been occurring rather often in MySQL as of late. SQL Injection assaults, however, may be avoided thanks to the safety mechanisms provided by My SQLi.
  • However, My SQLI does not handle the ACID transactions. These core MySQL transactions have API support.
  • There are such things as prepared statements in the MySQL database. On the other hand, MySQLi, which is a part of the main MySQL database, enabled prepared statements in My SQLi.
  • However, MySQLi is not a database in the same way that MySQL is.
  • MySQL is a relational database management system (RDBMS) that operates as a server and enables numerous users to access various databases simultaneously. MySQLi is an extension of MySQL.
  • MySQL does not need GUI tools to administer databases or manage the data contained inside them; MySQLi expands upon the functionality of MySQL and includes support for object-oriented interfaces, support for previously prepared statements, and better-embedded server support.


MySQL was undoubtedly a superior product to its successor, MySQLi. Nevertheless, whatever option you choose is dependent on the technological stack you have available. PHP has excellent support for MySQLi, which cannot be said of other languages.

If your application is built on the LAMP stack (Linux, Apache, MySQL, and Perl/Python/PHP), then you should make use of the MySQL database. This was made possible by the phenomenal community support offered by MySQL for LAMP-related architectural issues. Therefore, proceed with caution and keep up your academic pursuits.

As is the case with any software updates and improvements, there are very certainly going to be bugs in the next releases as well as those who stick to older versions of the application or find alternatives. The specifics of the situation as well as the opinions of the individuals had a role in the conclusion that MySQLi should be used rather than PDO or the MySQL Extension.
