This section provides a tutorial example on how to run the PHP engine as an interactive shell, php -a, which lets you to type in a PHP statement and see the result immediately on the screen.

In previous tutorial, I learned how to run the PHP engine to execute a PHP script stored in a file.

The PHP engine can also be used as an interactive shell, taking PHP script from the console and execute it one line at a time. interactively.

Here is a session of running the PHP engine as an interactive shell: 

herong> \php\php -a

Interactive shell

php > print "I am tossing a coin...\n";
I am tossing a coin...
php > $coin = rand(0,1);
php > if ($coin==1) {
php {    print "   Head\n";
php { } else {
php {    print "   Tail\n";
php { }
   Head
php > exit

C:\herong>

Cool. This is really a good tool to help leaning PHP. Just typing in a PHP statement, and watching the result displayed immediately on the screen.
