php：连表查询一对一和关联模型一对一

# Faker [](https://codecov.io/gh/fzaninotto/Faker) Faker is a PHP library that generates fake data for you. Whether you need to bootstrap your database, create good-looking XML documents, fill-in your persistence to stress test it, or anonymize data taken from a production service, Faker is for you. Faker is heavily inspired by Perl's [Data::Faker](http://search.cpan.org/~jasonk/Data-Faker-0.07/), and by ruby's [Faker](https://rubygems.org/gems/faker). Faker requires PHP >= 5.3.3.

Beatae nam sunt fugit // et sit et mollitia sed. // Fuga deserunt tempora facere magni omnis. Omnis quia temporibus laudantium // sit minima sint. ``` Even if this example shows a property access, each call to `$faker->name` yields a different (random) result. This is because Faker uses `__get()` magic, and forwards `Faker\Generator->$property` calls to `Faker\Generator->format($property)`. ```php <?php for ($i = 0; $i < 10; $i++) { echo $faker->name, "\n"; } // Adaline Reichel // Dr. Santa Prosacco DVM // Noemy Vandervort V // Lexi O'Conner // Gracie Weber // Roscoe Johns // Emmett Lebsack // Keegan Thiel // Wellington Koelpin II // Ms. Karley Kiehn V ``` **Tip**: For a quick generation of fake data, you can also use Faker as a command line tool thanks to [faker-cli](https://github.com/bit3/faker-cli). ## Formatters Each of the generator properties (like `name`, `address`, and `lorem`) are called "formatters". A faker generator has many of them, packaged in "providers". Here is a list of the bundled formatters in the default locale. ### `Faker\Provider\Base` randomDigit // 7 randomDigitNot(5) // 0, 1, 2, 3, 4, 6, 7, 8, or 9 randomDigitNotNull // 5 randomNumber($nbDigits = NULL, $strict = false) // 79907610 randomFloat($nbMaxDecimals = NULL, $min = 0, $max = NULL) // 48.8932 numberBetween($min = 1000, $max = 9000) // 8567 randomLetter // 'b' // returns randomly ordered subsequence of a provided array randomElements($array = array ('a','b','c'), $count = 1) // array('c') randomElement($array = array ('a','b','c')) // 'b' shuffle('hello, world') // 'rlo,h eoldlw' shuffle(array(1, 2, 3)) // array(2, 1, 3) numerify('Hello ###') // 'Hello 609' lexify('Hello ???') // 'Hello wgt' bothify('Hello ##??') // 'Hello 42jz' asciify('Hello ***') // 'Hello R6+' regexify('[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}'); // sm0@y8k96a.ej ### `Faker\Provider\Lorem` word // 'aut' words($nb = 3, $asText = false) // array('porro', 'sed', 'magni') sentence($nbWords = 6, $variableNbWords = true) // 'Sit vitae voluptas sint non voluptates.' sentences($nb = 3, $asText = false) // array('Optio quos qui illo error.', 'Laborum vero a officia id corporis.', 'Saepe provident esse hic eligendi.') paragraph($nbSentences = 3, $variableNbSentences = true) // 'Ut ab voluptas sed a nam.
