Enhance php cli scripts experiance.

Install

Use Composer

$ composer require shso/cli

Composer will load the library automatically.

Manually

Download the script:

$ curl -fL -O https://github.com/ShahinSorkh/php-cli/raw/master/src/cli.php
# Or using wget
$ wget https://github.com/ShahinSorkh/php-cli/raw/master/src/cli.php

Import in your scripts:

require_once './cli.php';

Script Usage

Assuming following cli:

$ php script.php -f --action ACTION -- ARG1 ARG2 ARG3

Count arguments

cli\argc(); // returns 3

Get arguments

cli\arg(); // returns ['script.php', 'ARG1', 'ARG2', 'ARG3']
cli\arg(2); // returns 'ARG2'
cli\arg(4, 'foo'); // returns 'foo'

Get options

cli\opt(); // returns ['f' => true, 'action' => 'ACTION']
cli\opt('f'); // returns true
cli\opt('action'); // returns 'ACTION'
cli\opt('q'); // returns null
cli\opt('foo', 'bar'); // returns 'bar'

Define usage

You can define a strict usage with fixed options and arguments. To do so, you should use cli\usage() method which takes an array as argument with possible keys of args, opts, desc.

Define arguments

Arguments can be optional.

cli\usage([
    'args' => [ 'REQUIRED_ARG', '[OPTIONAL_ARG]' ],
]);

Define options

Options can be optional and can accept arguments. Also options can be short or long.

cli\usage([
    'opts' => [
        '-f' => null, // optional, without arg, short
        '*c' => null, // required, without arg, short
        '-o' => 'OPT_ARG', // optional, with arg, short
        '-no-dev' => null, // optional, without arg, long
        '*config' => 'CONFIG', // required, with arg, long
    ],
]);

Define additional descriptions

If you need to describe about options or arguments, you can do so.

cli\usage([
    'args' => [ 'CONFUSING_ARG' ],
    'opts' => [
        '-f' => null,
    ],
    'desc' => [
        'CONFUSING_ARG' => 'Some descriptions that make the arg not confusing!',
        '-f' => 'Describe -f option can force the operation or whatever.',
    ],
]);

Command Line Usage

This package supports following syntax:

$ php script.php --opt --opt-with-arg OPT_ARG -- ARG [OPTIONAL_ARG]

Passing arguments

• Arguments has to be the last values. This means the following syntax is not acceptable:

$ php script.php ARG1 --opt1 ARG2 --opt2 OPT2_ARG ARG3 ARG4

Whenever an argument detected, every value after that is considered arguments. Means all of ARG1, --opt1, ARG2, --opt2, OPT2_ARG, ARG3, ARG4, are separate arguments.

• Every non-option value after an option, is considered the argument of the option. This means in the following syntax, ARG1 would be available as the value of the --op1 option (see below):

$ php script.php --op1 ARG1

If you need a boolean option and some arguments, use -- before arguments. like:

$ php script.php --op1 -- ARG1

• If you need input from stdin, use -. like:

$ php script.php - < somefile.txt
$ cat somefile.txt | php script.php -

It is possible to pass other arguments and options alongside.

Passing options

Every passed value starting with - before the first detected argument, is an option. Options can get additional value as their argument. like:

$ php script.php -f --file SOME_FILE
$ php customzipcompress.php --rm --compression best -f FILE1,FILE2 -d DIR1

If you are going to pass arguments, options has to be terminated with --. like:

$ php script.php -t -g OPT_ARG -- ARG1
