Although PHP is most commonly used to write web applications, it can also be used for scripts that run from a command line interface (CLI). The CLI environment is a little different than the web environment, and PHP's current documentation doesn't make it easy to locate the relevant pieces.
Arguments
Predefined variables:
$argccontains the number of arguments passed to the current script$argv[]contains an array of all the arguments passed to the script$argv[0]is always the name that was used to run the script.
Note that these variables are only present in the global scope; to use them inside of objects, they will need to be passed in somehow.
Other:
getopt()parses individual arguments in a standard way- Note that this ignores any options listed after non-options.
cli_get_process_title()cli_set_process_title()
See also file/glob for interfacing with the CLI environment's file-globbing services
Interactivity
- GNU Readline manages editable input lines
fgetc()reads a single character, but waits for a CRLF- See the comments for ways to wait for the user to actually just press a single character.
- ncurses: PECL package last updated in 2012
