What is PHP?
PHP is an open-source, interpreted, and object-oriented scripting language that is especially suited for web development and can be embedded in HTML.
Why do we use PHP?
- PHP is a server-side scripting language embedded in HTML.
- PHP is used to manage or create dynamic content, databases, session tracking, and even building e-commerce sites.
Advantages of PHP
- PHP is a recursive acronym for “PHP: Hypertext Preprocessor“.
- It is integrated with a number of popular databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix and Microsoft SQL Server.
- PHP is pleasingly zippy in its execution, especially when compiled as an Apache module on the Unix side.
The MySQL server once started, executes even very complex queries with huge result sets in recording setting-time.
- It supports a large number of major protocols such as POP3, IMAP, and LDAP. PHP4 added support for java and distributed object architectures (COM and COBRA).
- PHP is forgiving: PHP language tries to be as forgiving as possible.
- PHP syntax is C-like.
- PHP is simple and easy to learn.

But, you must have the basic knowledge of the following technologies for web development:
- HTML
- CSS
- JavaScript
- Ajax
- XML and JSON
- JQuery

Common use cases for PHP Tutorial For Beginners – Easy Learning
- Web application development. Full-stack PHP apps using vanilla PHP or Laravel/Symfony frameworks.
- WordPress plugin/theme development. Custom functionality for the world’s most popular CMS.
- API development. REST or GraphQL endpoints serving mobile apps and SPAs.
- CLI tools. Command-line scripts for cron jobs, data migration, or automation.
- Legacy code maintenance. PHP powers a large share of the web; understanding it is a durable skill.
Working code example
<?php
declare(strict_types=1);
class UserService {
public function getGreeting(string $name): string {
if ($name === "") {
throw new InvalidArgumentException("Name is required");
}
return "Welcome, " . htmlspecialchars($name);
}
}
$service = new UserService();
echo $service->getGreeting("Alice");
?>
Best practices
- Enable strict types. declare(strict_types=1) at the top of every file catches type coercion bugs.
- Use Composer. Modern PHP uses Composer for dependency management, autoloading, and PSR-4 class naming.
- Follow PSR standards. PSR-12 for coding style, PSR-4 for autoloading, PSR-3 for logging.
- Write unit tests with PHPUnit. Aim for 70%+ code coverage on business-critical modules.
- Use static analysis. PHPStan or Psalm catch many bugs before code runs.
Common pitfalls
- Global state. Overusing global variables makes testing hard. Prefer dependency injection.
- SQL concatenation. Always use prepared statements. Never concatenate user input into SQL strings.
- Missing type declarations. Old PHP allowed loose types. Modern PHP encourages strict typing everywhere.
- Ignoring errors. Set error_reporting(E_ALL) in development. Handle errors explicitly in production.
