Rando-PHP

RandoPHP is a PHP open-source package for random stuff. With this package you can:

Draw: Extract random items (sample) from an array. This is useful when you want to "draw" some numbers or items;
Generate: useful for create random items/sequences:
- item like integer, byte, boolean, float, lat/long coordinates, char (numeric, alphabetic, alphanumeric);
- sequences like an array of integers or chars;

With the fluent interface, you can control some things like:

minimum and maximum value you want to create;
how many items you want to create;
for sequences if you want or not duplicates ([1,5,3,1,1], 1 is duplicate or [1,6,5,3,8], no duplicates);
And other stuff, see the documentation for more options.

Installation

You can install the package via composer:

composer require hi-folks/rando-php

Usage

To import the right class:

use HiFolks\RandoPhp\Randomize;

Generate Char

Sometimes you want to obtain a random char, for example, a numeric char:

Randomize::char()->numeric()->generate();

Or you might want an alphabetic char:

Randomize::char()->alpha()->generate();

You can even do both!

Randomize::char()->alphanumeric()->generate();

You can generate a lower case char:

Randomize::char()->alpha()->lower()->generate();

You can generate an upper case char:

Randomize::char()->alpha()->upper()->generate();

You can generate a special character. A special character is one of '!"#$%&'()*+,-./:;<=>?@[]^_`{|}~':

Randomize::char()->specialCharacters()->generate();

Generate Boolean

Sometimes you want to obtain a random boolean true or false (flip a coin):

$randomBool = Randomize::boolean()->generate();

Generate a Float

Sometimes you want to obtain a random float (default min-max range of 0.0 - 1.0). For example, you want to generate a random temperature for a day:

$randomFloat = Randomize::float()->generate();

Or you can set the min-max range of 0 - 90, which is equivalent to ->min(0)->max(90)

$randomFloat = Randomize::float()->min(0)->max(90)->generate();

Generate an Integer

Sometimes you want to obtain a random integer (min-max range). For example, you want to roll the dice:

$randomNumber = Randomize::integer()->min(1)->max(6)->generate();

The same thing using range() method, instead of min() and max():

$randomNumber = Randomize::integer()->range(1,6)->generate();

You can use a shortcut helper to generate an integer calling the constructor with min and max parameters:

$randomNumber = Randomize::integer(1,6)->generate();

Generate bytes

Sometimes you want to obtain some random bytes (hexadecimal). For example, you want to generate a random RGB color (a hex triplet in hexadecimal format):

$randomRGB = Randomize::byte()->length(3)->generate();

Generate a Date

Sometimes you want to obtain a random date. For example, you want to generate a random date:

$randomDate = Randomize::datetime()->generate();

By default, a date between the first day of the current year to the last day of the current year. If you want to define the range, for example, a range of 01 Jan 2020 to 10 Jan 2020, you can use min() and max() methods:

$randomDate = Randomize::datetime()->min('2020–01–01')->max('2020–01–10')->generate();

You can even specify your preferred format for the random date generated, by using the format() method:

$randomDate = Randomize::datetime()->format('d-M-Y')->generate();

You can use min() and max() with format() method:

$randomDate = Randomize::datetime()->min('2020–01–01')->max('2020–01–10')->format('d-M-Y')->generate();

With the latest example, you can obtain something like "05-Jan-2020".

Generate sequences

Sometimes, you want to obtain some random sequences. For example, you want to roll the dice 15 times:

$randomRolls = Randomize::sequence()->min(1)->max(6)->count(15)->generate();

Sometimes you want to obtain some random char sequences. For example, char sequences of length 10:

$randomChars = Randomize::sequence()->chars()->count(10)->generate();

Or you might want numeric char sequences.

$randomChars = Randomize::sequence()->chars()->numeric()->count(10)->generate();

Or you might want alphabetical char sequences.

$randomChars = Randomize::sequence()->chars()->alpha()->count(10)->generate();

Yes, even both.

$randomChars = Randomize::sequence()->chars()->alphanumeric()->count(10)->generate();

You want 20 lowercase chars:

Randomize::sequence()->chars()->alphaLowerCase()->count(20)->asString()->generate();

You want 20 upper case chars:

Randomize::sequence()->chars()->alphaUpperCase()->count(20)->asString()->generate();

Sometimes you want to obtain some random sequences with no duplicates. For example, you want to play "Tombola" (extracting numbers from 1 to 90 with NO duplicates):

$randomTombola = Randomize::sequence()->min(1)->max(90)->count(90)->noDuplicates()->generate();

Sometimes you want to obtain some random char sequences with no duplicates.

$randomChars = Randomize::sequence()->chars()->count(10)->noDuplicates()->generate();

Or you might want numeric char sequences with no duplicates. For example, char sequences of length 10:

$randomChars = Randomize::sequence()->chars()->numeric()->count(10)->noDuplicates()->generate();

Or you might want alphabetical char sequences with no duplicates.

$randomChars = Randomize::sequence()->chars()->alpha()->count(10)->noDuplicates()->generate();

Yes, even both and with no duplicates.

$randomChars = Randomize::sequence()->chars()->alphanumeric()->count(10)->noDuplicates()->generate();

Random String

If you want to generate a random string (alphanumeric, only letters, only numbers, with no duplication, lower case, upper case etc) you can use random chars generation. To generate a string use Randomize::chars():

$string = Randomize::chars()->generate();

The default behavior is:

10 chars;
only letters (a-z);
lowercase;
duplication is allowed (the string 'aba' has a duplication for 'a' char).

You can change the default values with some methods and parameters. Method to set the type of chars (numeric, alpha, alphanumeric...):

alpha() : 'a-z', 'A-Z';
alphanumeric() : 'a-z', 'A-Z', '0-9';
numeric() : '0-9';
alphaLowerCase() : 'a-z';
alphaUpperCase() : 'A-Z';
specialCharacters() : !"#$%&'()*+,-./:;<=>?@[]^_`{|}~

You have also some methods to "control" the output, for example, avoid duplications:

unique(): it generates a string with at most one occurrence per character.

String with numeric chars ('0'-'9')

If you want to generate a string with 16 chars, made with numeric chars ('0'-'9'):

$string = Randomize::chars(16)->numeric()->generate();

You could obtain something like this '3963233500573002'.

String with 20 chars, lower case, just letters, no dups

If you want to obtain a string with 20 chars, lower case and just letters ('a'-'z'), and you want to avoid character duplications ( alphaLowerCase() and unique() ):

$string = Randomize::chars(20)->alphaLowerCase()->unique()->generate();

You could obtain something like this: 'nmbsjhrgdyfxwoltqkzp'.

String with 20 chars, letters and special characters

If you want to obtain a string with 20 chars, with letters and special characters:

$string = Randomize::chars(20)->specialCharacters()->alpha()->generate();

You could obtain something like this: 'IOgPckeGGifrD%DRy[*!'.

Draw random stuff

If you have a list of values and you want to extract/select/draw one or more elements, you could use the Draw class instead of Randomize. For using the Draw class you need to import it:

use HiFolks\RandoPhp\Draw;

Suggest which programming language you could use in your next project (random)

use HiFolks\RandoPhp\Draw;

$randomLanguage = Draw::sample(["PHP", "Python", "Golang", "Javascript"])->snap();
var_dump($randomLanguage);

Suggest which JS framework you could use in your next project (random)

$array=["React.js", "Vue.js", "Svelte.js", "Angular.js" , "Alpine.js", "Vanilla js"];
$randomJs = Draw::sample($array)->extract();

Extract 3 JS frameworks you could use in your next project

$array=["React.js", "Vue.js", "Svelte.js", "Angular.js" , "Alpine.js", "Vanilla js"];
$randomJs = Draw::sample($array)->count(3)->extract();

Extract 3 JS frameworks (duplicates allowed)

$array = ["React.js", "Vue.js", "Svelte.js", "Angular.js", "Alpine.js", "Vanilla js"];
$randomJs = Draw::sample($array)->count(3)->allowDuplicates()->extract();

Testing

composer test

If you want to see some coverage reports you can execute phpunit command with coverage-text option:

vendor/bin/phpunit --coverage-text

Warning ⚠️

Under the hood, RandoPHP uses some native PHP functions like:

array_rand(): PHP Doc for array_rand;
random_int(): PHP Doc for random_int;
shuffle(): PHP Doc for shuffle;
random_bytes(): PHP Doc for random_bytes.

These PHP functions use a pseudo-random number generator that is not suitable for cryptographic purposes.
