1、Understanding PHP
PHP, which stands for Hypertext Preprocessor, is an open-source, server-side scripting language. It was created by Rasmus Lerdorf in 1994 and has since become one of the most widely used programming languages in the world. PHP is compatible with various servers, including Apache, Microsoft IIS, and Netscape iPlanet Server.
1、1 PHP syntax
PHP syntax is similar to C, Java, and Perl, making it easy for developers to learn. PHP code is written in HTML files, which can be executed on the server. Here's an example of a simple PHP script:
<?php echo "Hello, World!"; ?>
In this script,<?php and?> delimit the PHP code. Theecho statement is used to display the message "Hello, World!" on the webpage.
2、Installing PHP

One of the key features of PHP is its ability to interact with databases. MySQL is a popular database management system that works well with PHP. Here's how to connect to a MySQL database using PHP:
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
