PHP Command Line Interface 'CLI'
▫ Allows you to parse and execute files by using parameter -f fol- ▫ lowed by the name of the file to be executed. ▫ ▫ Using parameter -r you can directly execute PHP code sim- ▫ ply as you would do inside a .php file when using the ▫ eval() function. ▫ ▫ If none of -r or -f 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. ▫ ▫ PHP's Command Line Interface first showed up in PHP 4.2.0, as experimental ▫ functionality. With PHP 4.3.0 the CLI became an official server API.
