Chapter 16: Command-Line PHP Utilities 567 The syntax for short arguments in Console_Getopt::getopt() is fairly simple. List each short argument, order doesn t matter. If an argument requires a parameter (like s in the listing above) you follow it with a colon (as we did above). If the parameter is optional, you add two colons. The short and the long argument lists are the expected lists of arguments. The Console_Getopt::getopt() function returns an error object if the user enters an invalid argument that is not listed in the short or long expected argument list passed to it. If the user enters valid arguments and argument options, the getopt() method returns the list of options supplied by the user in an array. The getCommandLineOptions() function goes through the valid list of user-entered arguments, removes - characters from each argument, and makes an associative array called $cmd, using the argument name as the key and the argument value as the value. For example, if the user runs this script as follows: ./cmd_options.php -h -s 100 the $cmd array looks like the following: Array ( [h] => 1 [s] => 100 ) Similarly, if the user runs it as ./cmd_options.php -h –size 100 –king=burger the $cmd array looks like the following: Array ( [h] => 1 [size] => 100 [king] => burger )
