Chainable method for making any formatter optional.

Chainable method for making any formatter unique.

// will never return twice the same value
$faker->unique()->randomElement(array(1, 2, 3));

Chainable method for forcing any formatter to return only valid values.

The value validity is determined by a function passed as first argument.

$values = array();
$evenValidator = function ($digit) {
  return $digit % 2 === 0;
};
for ($i=0; $i < 10; $i++) {
  $values []= $faker->valid($evenValidator)->randomDigit;
}
print_r($values); // [0, 4, 8, 4, 2, 6, 0, 8, 8, 6]

Returns a random number between 0 and 9

Returns a random number between 1 and 9

Generates a random digit, which cannot be $except

Returns a random integer with 0 to $nbDigits digits.

The maximum value returned is mt_getrandmax()

Return a random float number

Returns a random number between $int1 and $int2 (any order)

Returns the passed value

Returns a random letter from a to z

Returns a random ASCII character (excluding accents and special chars)

Returns randomly ordered subsequence of $count elements from a provided array

Returns a random element from a passed array

Returns a random key from a passed associative array

Returns a shuffled version of the argument.

This function accepts either an array, or a string.

Returns a shuffled version of the array.

This function does not mutate the original array. It uses the Fisher–Yates algorithm, which is unbiased, together with a Mersenne twister random generator. This function is therefore more random than PHP's shuffle() function, and it is seedable.

Returns a shuffled version of the string.

This function does not mutate the original string. It uses the Fisher–Yates algorithm, which is unbiased, together with a Mersenne twister random generator. This function is therefore more random than PHP's shuffle() function, and it is seedable. Additionally, it is UTF8 safe if the mb extension is available.

Replaces all hash sign ('#') occurrences with a random number Replaces all percentage sign ('%') occurrences with a not null number

Replaces all question mark ('?') occurrences with a random letter

Replaces hash signs ('#') and question marks ('?') with random numbers and letters An asterisk ('*') is replaced with either a random number or a random letter

Replaces * signs with random numbers and letters and special characters

Transforms a basic regular expression into a random string satisfying the expression.

Converts string to lowercase.

Uses mb_string extension if available.

Converts string to uppercase.

Uses mb_string extension if available.

Generate a text string by the Markov chain algorithm.

Depending on the $maxNbChars, returns a random valid looking text. The algorithm generates a weighted table with the specified number of words as the index and the possible following words as the value.
