PHP Core

1. Introduction

# Usage

<html><body>
<?php echo "<p>This is a php-generated paragraph.</p>" ?>
<body></html>

PHP(Personal Home Page): Hypertext Processor is used as a web-content renderer, and widely used in the industry environment. The example above shows that the php script can be directly injected into a html page (by using indentifer <?php and ?> ), and will be executed by the php complier to be the html code. From the user’s side this is showed as:

<html><body>
<p>This is a php-generated paragraph.</p>
<body></html>

Where the parameter of echo is printed to the page. Noticed that if a page is pure php code then the end identifer ?> can be omitted.

The framework of PHP includes Laravel, Symfony, Yii, and so on.
