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:

  • $argc contains 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.

Other:

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.
