Overview
Why Learn PHP?
PHP is a widely used server-side
programming language that’s become increasingly fast and powerful over the
years. PHP works well with HTML and databases, making it a great language for
anyone interested in building dynamic web applications. php

An introductory example
<!DOCTYPE html>
<html>
<head>
<title>Example</title>
</head>
<body>
<?php
echo "Hi, I'm a PHP script!";
?>
</body>
</html>
<html>
<head>
<title>Example</title>
</head>
<body>
<?php
echo "Hi, I'm a PHP script!";
?>
</body>
</html>
Instead of lots of commands
to output HTML (as seen in C or Perl), PHP pages contain HTML with embedded
code that does "something" (in this case, output "Hi, I'm a PHP
script!"). The PHP code is enclosed in special
What distinguishes PHP from something like
client-side JavaScript is that the code is executed on the server, generating
HTML which is then sent to the client. The client would receive the results of
running that script, but would not know what the underlying code was. You can
even configure your web server to process all your HTML files with PHP, and
then there's really no way that users can tell what you have up your sleeve.
PHP Data
Types
Variables can store data of different types, and different data
types can do different things.
PHP supports the following data types:
- String
- Integer
- Float
(floating point numbers - also called double)
- Boolean
- Array
- Object
- NULL
- Resource
PHP String
A string is a sequence of characters, like "Hello
world!".
A string can be any text inside quotes. You can use single or
double quotes:
Example:-
<?php
$x = "Hello world!";
$y = 'Hello world!';
echo $x;
echo "<br>";
echo $y;
?>
PHP
Integer
An integer
data type is a non-decimal number between -2,147,483,648 and 2,147,483,647.
Rules for integers:
- An
integer must have at least one digit
- An integer must not have a decimal
point
- An integer can be either positive or
negative
- Integers can be specified in three
formats: decimal (10-based), hexadecimal (16-based - prefixed with 0x) or
octal (8-based - prefixed with 0)
