Hypertext Preprocessor (PHP) is a programming language that lets web developers make dynamic content that works with databases. PHP is mostly used to make software that runs on the web. This tutorial will help you get started with PHP.
Why Study PHP?
PHP started out as a small open source project that grew as more and more people found out how useful it was. In 1994, Rasmus Lerdorf put out the first version of PHP.
PHP is a MUST for students and working professionals who want to become great Software Engineers, especially if they work in Web Development. I will list some of the most important reasons why you should learn PHP:
PHP stands for \”PHP: Hypertext Preprocessor,\” which is also an acronym.
PHP is a scripting language that runs on the server. It is built into HTML. It is used to manage dynamic content, databases, session tracking, and even to build whole e-commerce sites.
It works with MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server, among other popular databases.
PHP runs quickly, especially when it is compiled as an Apache module on a Unix system. Once the MySQL server is running, it can run even very complicated queries with very large sets of results in record time.
PHP works with a lot of important protocols, like POP3, IMAP, and LDAP. PHP4 made n-tier development possible for the first time by adding support for Java and distributed object architectures (COM and CORBA).
PHP is forgiving. The PHP language tries to be as forgiving as possible.
PHP Syntax is C-Like.
What PHP is and what it does
PHP is useful because of five things that make it possible. −
- Simplicity
- Efficiency
- Security
- adaptability
- Familiarity
Example Using PHP, \”Hello, Coder!\”
I\’m going to give you a small, standard PHP \”Hello World\” programme to get you interested in PHP.
<html>
<head>
<title>Hello Coder</title>
</head><body> <?
php echo \”Hello, Coder!\”;?>
</body>
</html>
Applications of PHP
As was already said, PHP is a language that is used a lot on the web. I\’ll list some of them here:
- PHP works with the system, so it can create, open, read, write, and close files on a system.
- PHP can handle forms, which means it can get data from files, save data to files, send data via email, and give data back to the user.
- Using PHP, you can add, delete, and change things in your database.
- You can look at the cookie variables and set cookies.
- Using PHP, you can make it so that only certain people can see certain pages of your website.
- It can hide information.
