如何使用Laravel Faker在最小和最大字符数之间生成随机字符串

Question

I'm looking for a way to generate random string between min and max number of characters using laravel Faker. I have to create random strings between 4 and 20 characters. This method str_random will generate exactly 20 characters, but how to specify min number of characters?

<?php

use Faker\Generator as Faker;

$factory->define(App\User::class, function (Faker $faker) {
    return [
        'name' => str_random(20),
    ];
});

Updated: I'm using the following code now as a workaround:

'name' => substr($faker->name(), 0, rand(4, 20))

</div>

You could use regexify and and this let's you control what characters could be in the randomly generated string like this:

<?php

use Faker\Generator as Faker;

$factory->define(App\User::class, function (Faker $faker) {
    return [
        'name' => $faker->regexify('[A-Za-z0-9]{' . mt_rand(4, 20) . '}'),
    ];
});

Another option is $faker->realText(mt_rand(4, 20))
