getopt
GETOPT(3) 1 GETOPT(3)getopt - Gets options from the command line argument listSYNOPSIS
array getopt (string $options, [array $longopts])
DESCRIPTION
Parses options passed to the script.
PARAMETERS
o $options
- Each character in this string will be used as option characters and matched against options passed to the script starting with a
single hyphen ( -). For example, an option string "x" recognizes an option -x. Only a-z, A-Z and 0-9 are allowed.
o $longopts
- An array of options. Each element in this array will be used as option strings and matched against options passed to the script
starting with two hyphens ( --). For example, an longopts element "opt" recognizes an option --opt.
The $options parameter may contain the following elements:
oIndividual characters (do not accept values)
oCharacters followed by a colon (parameter requires value)
oCharacters followed by two colons (optional value)
Option values are the first argument after the string. If a value is required, it does not matter whether the value has leading white
space or not. See note.
Note
Optional values do not accept " " (space) as a separator.
Note
The format for the $options and $longopts is almost the same, the only difference is that $longopts takes an array of options
(where each element is the option) whereas $options takes a string (where each character is the option).
RETURN VALUES
This function will return an array of option / argument pairs or FALSE on failure.
Note
The parsing of options will end at the first non-option found, anything that follows is discarded.

"required:", // Required value
"optional::", // Optional value
"option", // No value
"opt", // No value
);
$options = getopt($shortopts, $longopts);
var_dump($options);
?>
