Getting Started with PHP for Web Development

Get a proper working environment before you write your first script.

1. Requirements of the PHP Setup version.
2. To start building PHP based applications, you require:
3. Local server environment such as XAMPP, MAMP or WAMP.
4. A code editor or IDE
5. Basic knowledge of HTML and CSS.
6. An optional database system e.g. MySQL or MariaDB.

After the installation, all one needs to do is create a file with the .php extension and place it in the server directory, often referred to as htdocs or www. Subsequently, open it with your browser with a URL like: localhost/yourfilename.php

PHP Basics for Web Development

When you are ready, begin the study of fundamental blocks of the language.

PHP Variables

Variables hold data in the form of text, numbers, or values that are in a form. PHP has all variables beginning with a dollar sign.

Example

$name = "John";

PHP Operators

Calculations or comparisons are done with the help of the operators.

Examples

for addition
== to compare values
= to assign values

PHP Functions

Functions enable you to have reusable blocks of code, and thus you do not repeat yourself.

Example

function greet() {

   echo "Welcome to PHP";

}

PHP Conditional Statements

The program makes decisions with the assistance of conditional statements.

Example

if($age > 18){

   echo "Eligible";

}

PHP Loops

Repetitions can be seen as loops where the action repeats until a condition is reached.

Example

for($i=0; $i<5; $i++){

   echo $i;

}

PHP Arrays

Lots of values are held in arrays under one variable.

Example

$fruits = array(Apples, bananas, mango);

These fundamental skills are a stepping stone to the higher levels of understanding, such as object-oriented programming, database work, authentication of users, and the creation of full-scale applications.
