Faker Command Line Tool

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.

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

vero,omnis

Output formats

You can use different output formats by definint the --format option. JSON is the default format.

JSON output

$ ./bin/faker.php word

[
    "culpa",
    "consequatur",
    "quisquam",
    "recusandae",
    "asperiores",
    "accusamus",
    "nihil",
    "repellat",
    "vero",
    "omnis"
]

$ ./bin/faker.php --count 5 words 2

[
    [
        "culpa",
        "consequatur"
    ],
    [
        "quisquam",
        "recusandae"
    ],
    [
        "asperiores",
        "accusamus"
    ],
    [
        "nihil",
        "repellat"
    ],
    [
        "vero",
        "omnis"
    ]
]

XML output

$ ./bin/faker.php --format xml word

<?xml version="1.0"?>
<array>
  <item>culpa</item>
  <item>consequatur</item>
  <item>quisquam</item>
  <item>recusandae</item>
  <item>asperiores</item>
  <item>accusamus</item>
  <item>nihil</item>
  <item>repellat</item>
  <item>vero</item>
  <item>omnis</item>
</array>

CSV output

$ ./bin/faker.php --format csv word

culpa
consequatur
quisquam
recusandae
asperiores
accusamus
nihil
repellat
vero
omnis

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.

$ ./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.

$ ./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.
