Hello.php - My First PHP Script
<< Introduction and Installation of PHP
<< PHP Tutorials - Herong's Tutorial Examples
This section provides a tutorial example on how to write the first PHP script, Hello.php, and run it with PHP CLI and PHP CGI.
Use any text editor like notepad, and enter the first PHP script, Hello.php:
Hello <?php echo "world!"; ?>
Run it with PHP CLI first:
>\php\php Hello.php Hello world!
Then run it with PHP CGI:
>\php\php-cgi Hello.php Content-type: text/html X-Powered-By: PHP/5.0.4 Hello world!
As expected, both versions of the PHP engine worked nicely. PHP CGI version did generate the HTTP response header for me.
