PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. This is the command line interface that enables you to do the following:
You can parse and execute files by using parameter -f followed by the name of the file to be executed.
Using parameter -r you can directly execute PHP code simply as you would do inside a .php file when using the eval() function.
It is also possible to process the standard input line by line using either the parameter -R or -F. In this mode each separate input line causes the code specified by -R or the file specified by -F to be executed. You can access the input line by $argn. While processing the input lines $argi contains the number of the actual line being processed. Further more the parameters -B and -E can be used to execute code (see -r) before and after all input lines have been processed respectively. Notice that the input is read from STDIN and therefore reading from STDIN explicitly changes the next input line or skips input lines.
PHP also contains an built-in web server for application development purpose. By using the -S option where addr:port point to a local address and port PHP will listen to HTTP requests on that address and port and serve files from the current working directory or the docroot passed by the -t option.
If none of -r -f -B -R -F -E or -S is present but a single parameter is given then this parameter is taken as the filename to parse and execute (same as with -f). If no parameter is present then the standard input is read and executed.

You can use a shebang line to automatically invoke php from scripts. Only the CLI version of PHP will ignore such a first line as shown below:
// your script
