php-fakerHow can I generate unique data with Laravel Faker?

You can generate unique data with Laravel Faker by using the unique() method. This method will generate a random unique value each time it is called.

For example:

$uniqueNumber = \Faker\Factory::create()->unique()->numberBetween($min = 1, $max = 9999);
echo $uniqueNumber;

Output example

5577

The code above will generate a random number between 1 and 9999.

The parts of the code are:

• \Faker\Factory::create() - creates a new Faker\Generator instance
• unique() - the method used to generate a unique value
• numberBetween($min = 1, $max = 9999) - generates a random number between 1 and 9999
