PHP, the versatile open-source server-side scripting language, serves as the backbone of numerous web development projects. Beyond web development, it extends its utility to diverse applications, including Graphical User Interfaces (GUIs). In this comprehensive guide, we will delve into the world of PHP, unraveling its inner workings, and gaining an understanding of its fundamental features. By the end of this journey, you will be equipped to craft your inaugural Hello World program in PHP.
The Meaning of PHP Initially standing for Personal Homepage, PHP has since evolved into a recursive acronym: Hypertext Preprocessor. Its recursive nature lies in the fact that the first word, “Personal,” is itself an abbreviation, resulting in a layered interpretation. Having been introduced 26 years ago, PHP has made significant strides, with version 8 emerging in November 2020, although version 7 remains the most prevalent.
PHP primarily operates on the Zend engine, the most widely adopted implementation. Alternate implementations like parrot, HPVM (Hip Hop Virtual Machine), and Hip Hop, developed by Facebook, also exist. Notably, PHP is chiefly employed for constructing web servers, facilitating execution both in browsers and command-line environments.
However, the reality suggests otherwise. PHP continues to serve as the driving force behind nearly 80% of all websites today. Thus, if you visit ten websites daily, it’s highly probable that eight of them rely on PHP.
Furthermore, PHP job opportunities remain robust, surpassing many other programming languages on platforms like Indeed. Proficient PHP developers find lucrative opportunities crafting WordPress themes and plugins, with the average annual salary for a PHP developer in the United States reaching $86,000.
Creating Your First Hello World Program in PHP Now that you’ve gained insights into PHP’s advantages and its enduring relevance, it’s time to embark on crafting your inaugural Hello World program:
You can also assign your greeting message to a variable and use the
echo statement to display it:
localhost/your-folder-name/index.php. Ensure that your WAMP or XAMP server is running for the code to execute correctly.
