PHP stands for the “PHP Hypertext Preprosessor”. PHP is a server scripting language and a powerful tool to create the interactive and dynamic web pages to add the features to the web pages. PHP is freely available and cost nothing. PHP is easy to learn and allow very simple coding for the web pages. PHP code is interpreted by a web server with a PHP processor module, which generates the resulting web page: PHP commands can be embedded directly into an HTML source document rather than calling an external file to process data. The first thing you need, before you start learning PHP, is a basic understanding of HTML.
<!DOCTYPE html> <html> <body> <?php echo "My first PHP script!"; ?> </body> </html>
