Generate random strings or numeric values

Random

Generate random strings, numbers, bytes, patterns, and a lot more

Features

It generates cryptographically secure pseudo-random bytes (using random_bytes() and random_int()) to make:

• Strings
• Numbers (strings or integers)
• Upper, lower and mixed case
• Prefixed and suffixed random strings
• Hexadecimal
• Regex patterns ([abcd], [aeiou], [A-Z0123], [0-9a-f])
• Raw strings, giving you whatever random_bytes() generates

Faker

If you have Faker installed it falls back to it, giving you access to random names, dates, cities, phones, and a lot more.

Install

Via Composer

$ composer require pragmarx/random

Usage

Basic array usage

$this->random = new PragmaRX\Random\Random();

$this->random->get(); /// will generate an alpha string which is the same of

$this->random->alpha()->get();

Should give you 16 chars (default size) string

   Ajv3ejknLmqwC36z

Defining the size

$this->random->size(32)->get();

Upper and lower case

$this->random->uppercase()->get();
$this->random->lowercase()->size(255)->get();

To get back to mixed case you can just:

$this->random->mixedcase()->get();

Defining a pattern

The pattern method uses regex, so you can:

$this->random->pattern('[abcd]')->get();

$this->random->pattern('[A-F0-9]')->get(); /// Hexadecimal

To get

   abcddcbabbacbbdabbcb

Numeric and Integer

The pattern method uses regex, so you can:

$this->random->numeric()->start(10)->end(20)->get();

To get

   (int) 18

But if you set the size

$this->random->numeric()->size(3)->get();

You'll get a string

   (string) 123

Hexadecimal

$this->random->hex()->size(10)->get();

Hexadecimal is uppercase by default, but you can get a lowercase by doing:

$this->random->hex()->lowercase()->get();

Prefix && Suffix

$this->random->hex()->prefix('#')->size(6)->lowercase()->get();

And you should get a random CSS color:

#fafafa

Of course, the same works for suffixes

$this->random->prefix('!')->suffix('@')->get();

Trivia

There are currently 43982 questions in the trivia database, and this is how you get them:

$this->random->trivia()->get();

$this->random->trivia()->count(2)->get();

You'll need to install the Trivia database package:

$ composer require pragmarx/trivia

Faker

If you install Faker

composer require fzaninotto/faker

You'll also have access to all of the Faker features, like:

$this->random->city()->get();

And also use all other features of Random

$this->random->prefix('city: ')->city()->lowercase()->get();

You can also change the faker class, you another one pleases you more:

$this->random->fakerClass(AnotherFaker\Factory::class)->date()->get();

Raw strings

Usually the package returns characters in the range of Base64 (A to Z, a to z and 0 to 9), but you can completely disable this feature and make it return whatever random_bytes() generates:

$this->random->raw()->get();
