Faker is a PHP library that generates fake data for you.
This is a command line tool for easy generation of fake data in a static way., (*1)
Usage
As a Phar (Recommended)
You can find the latest phar on the releases page., (*2)
$ wget https://github.com/bit3/faker-cli/releases/download/1.4/faker.phar
$ ./faker.phar
As a Composer Install
$ composer create-project bit3/faker-cli
$ cd faker-cli
$ ./bin/faker.php
Parameters and arguments
$ ./bin/faker.php
--locale (-l) # The locale to used. (default: "en_US")
--seed (-s) # The generators seed.
--pattern (-p) # The printf pattern. (default: "%s")
--delimiter (-d) # The delimiter is used by the csv and printf format.
--enclosure (-e) # The enclosure is used by the csv and printf format.

<args1>..<argsN> # Arguments for the type, e.g. "words 5" will generate 5 words.
Single value generator example
$ ./bin/faker.php word
culpa
consequatur
quisquam
recusandae
asperiores
accusamus
nihil
repellat
vero
omnis
Multi value generator example
$ ./bin/faker.php --count 5 words 2
culpa,consequatur
quisquam,recusandae
asperiores,accusamus
nihil,repellat
vero,omnis
You can use different output formats by definint the --format
option. JSON is the default format., (*3)

"culpa",
"consequatur",
"quisquam",
"recusandae",

"repellat",
"vero",
"omnis"
]
$ ./bin/faker.php --count 5 words 2

[
"culpa",
"consequatur"
],
[

PHP output
$ ./bin/faker.php --format php word
array (
0 => 'culpa',
1 => 'consequatur',
2 => 'quisquam',
3 => 'recusandae',
4 => 'asperiores',
5 => 'accusamus',
6 => 'nihil',
7 => 'repellat',
8 => 'vero',
9 => 'omnis',
)
printf and vprintf output
The printf and vprintf output are mostly equal. But printf
is designed for single value generator types e.g. safeEmail
and vprintf
is designed for multi value generator types e.g. words 5
., (*4)
$ ./bin/faker.php --format printf \
--pattern "INSERT INTO emails (uuid, email) VALUES (UUID(), %s);" \
--enclosure "'" \
safeEmail
INSERT INTO emails (uuid, email) VALUES (UUID(), 'dbednar@example.com');
INSERT INTO emails (uuid, email) VALUES (UUID(), 'xhettinger@example.net');
INSERT INTO emails (uuid, email) VALUES (UUID(), 'gerald62@example.org');
INSERT INTO emails (uuid, email) VALUES (UUID(), 'miles91@example.com');
INSERT INTO emails (uuid, email) VALUES (UUID(), 'to\'conner@example.com');
INSERT INTO emails (uuid, email) VALUES (UUID(), 'bridgette.runolfsdottir@example.com');
INSERT INTO emails (uuid, email) VALUES (UUID(), 'fgoldner@example.org');
INSERT INTO emails (uuid, email) VALUES (UUID(), 'grimes.leo@example.org');
INSERT INTO emails (uuid, email) VALUES (UUID(), 'lilian.reynolds@example.net');
INSERT INTO emails (uuid, email) VALUES (UUID(), 'ratke.darlene@example.net');
./bin/faker.php --format vprintf \
--pattern "INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), %s, %s, %s);" \
--enclosure "'" \
words 3
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'est', 'illo', 'consequuntur');
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'dolorem', 'temporibus', 'commodi');
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'sint', 'reiciendis', 'sint');
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'sunt', 'eum', 'id');
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'tempora', 'rerum', 'occaecati');
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'corrupti', 'impedit', 'doloribus');
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'amet', 'consectetur', 'repudiandae');
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'est', 'id', 'amet');
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'odio', 'facere', 'nesciunt');
INSERT INTO keywords (uuid, keyword1, keyword2, keyword3) VALUES (UUID(), 'voluptas', 'quia', 'rerum');
You can also use printf
with multi value generator types, which will joined by the --delimiter
char, which is ,
by default., (*5)
$ ./bin/faker.php --format printf \
--pattern "INSERT INTO words (uuid, words) VALUES (UUID(), %s);" \
--delimiter ' / ' \
--enclosure "'" \
words 10
INSERT INTO words (uuid, words) VALUES (UUID(), 'est / illo / consequuntur / dolorem / temporibus / commodi / sint / reiciendis / sint / sunt');
INSERT INTO words (uuid, words) VALUES (UUID(), 'eum / id / tempora / rerum / occaecati / corrupti / impedit / doloribus / amet / consectetur');
INSERT INTO words (uuid, words) VALUES (UUID(), 'repudiandae / est / id / amet / odio / facere / nesciunt / voluptas / quia / rerum');
INSERT INTO words (uuid, words) VALUES (UUID(), 'ad / sed / esse / sed / exercitationem / sed / et / rem / esse / excepturi');
INSERT INTO words (uuid, words) VALUES (UUID(), 'animi / minus / qui / perferendis / quo / repudiandae / aliquam / dolorem / voluptas / fugiat');
INSERT INTO words (uuid, words) VALUES (UUID(), 'at / odit / dolorem / a / aperiam / dignissimos / ipsa / sunt / consequatur / alias');
INSERT INTO words (uuid, words) VALUES (UUID(), 'accusantium / voluptatum / autem / nobis / cumque / neque / modi / iure / voluptatem / error');
INSERT INTO words (uuid, words) VALUES (UUID(), 'molestiae / consequatur / alias / eligendi / corrupti / illum / commodi / molestiae / aut / repellat');
INSERT INTO words (uuid, words) VALUES (UUID(), 'id / quisquam / et / sit / consequuntur / aut / et / ullam / asperiores / molestiae');
INSERT INTO words (uuid, words) VALUES (UUID(), 'cupiditate / culpa / voluptatem / et / mollitia / dolor / sit / nisi / praesentium / qui');
It is recommend to use the --enclosure
option. each occurrence of the --enclosure
char will be escaped with the --escape
char, which is \\
by default., (*6)
