# getopt

(PHP 4 >= 4.3.0, PHP 5)

getopt -- Gets options from the command line argument list

## Description

array getopt ( string options [, array longopts] )

Returns an associative array of option / argument pairs based on the options format specified in options, or `FALSE` on an error.

On platforms that have the C function getopt_long, long options can be specified with the parameter longopts (as of PHP 4.3.0).

`<?php // parse the command line ($GLOBALS['argv']) $options = getopt("f:hp:"); ?>`

The options parameter may contain the following elements: individual characters, and characters followed by a colon to indicate an option argument is to follow. For example, an option string x recognizes an option -x, and an option string x: recognizes an option and argument -x argument. It does not matter if an argument has leading white space.

This function will return an array of option / argument pairs. If an option does not have an argument, the value will be set to `FALSE`.
