PHP Programming Examples: A Beginner‘s Guide with Practical Illustrations252

PHP, a server-side scripting language, is widely used for web development. Its ease of use and vast community support make it a great choice for beginners and experienced developers alike. This tutorial will guide you through several practical PHP programming examples, illustrating core concepts and techniques. We'll start with the very basics and gradually increase the complexity, covering fundamental aspects like variables, operators, control structures, functions, and arrays.

1. Hello, World! – Your First PHP Program

Every programming journey begins with the classic "Hello, World!" program. In PHP, it's incredibly simple:```php

```

This code snippet uses the `echo` statement to output the text "Hello, World!" to the browser. The `` tags define the beginning and end of a PHP code block.

2. Variables and Data Types

Variables are used to store data. PHP is dynamically typed, meaning you don't explicitly declare the data type of a variable. The type is determined at runtime.```php

```

This example demonstrates different data types: string, integer, float (floating-point number), and boolean. Variable names start with a dollar sign (`$`).

3. Operators

PHP supports various operators, including arithmetic, comparison, logical, and assignment operators.```php

```

This code illustrates arithmetic operators. The `.` operator is used for string concatenation.

4. Control Structures: Conditional Statements

Conditional statements allow you to execute different blocks of code based on certain conditions.```php
