PHP/CLI

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.

Functionality

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:

• getopt() parses individual arguments in a standard way
• cli_get_process_title()
• cli_set_process_title()
• glob() is the interface to the system's file-globbing function
