PHP code is a set of instructions written in the PHP programming language that can be executed by a web server to generate dynamic web pages. PHP is a server-side scripting language, which means that the PHP code is executed on the server and the resulting HTML output is sent to the client’s web browser.
PHP code is embedded in HTML code using special tags that start with . These tags tell the web server to start interpreting the code as PHP code, and to output the results of the code as HTML. PHP code can include variables, conditional statements, loops, functions, and other programming constructs.
Here’s an example of a simple PHP program that displays the current date and time:
<!DOCTYPE html>
<html>
<head>
<title>PHP Example</title>
</head>
<body>
<?php
echo "The current date and time is " . date("Y-m-d H:i:s");
?>
</body>
</html>
In this example, we’ve embedded PHP code between the tags. The PHP code calls the date function to get the current date and time in the format Y-m-d H:i:s, and uses the echo statement to display the result on the web page.
When this code is executed on the server, the PHP code is interpreted and the resulting HTML code is sent to the client’s web browser. The web page will display the current date and time, as generated by the PHP code.
