How to generate random number in Codeigniter?

@arnoldo.moen 

In CodeIgniter, you can use the random_string function from the string_helper library to generate a random string of a specified length. You can then convert this random string to an integer by using the intval function.

Here's an example of how you can use these functions to generate a random integer in CodeIgniter:

1
2
3
4
5
6
7

$this->load->helper('string');

// Generate a random string of length 8
$random_string = random_string('numeric', 8);

// Convert the random string to an integer
$random_integer = intval($random_string);

You can also use the rand function from PHP to generate a random integer. Here's an example of how you can use this function in CodeIgniter:

1
2

// Generate a random integer between 1 and 100
$random_integer = rand(1, 100);

Note that the rand function is not cryptographically secure, so it should not be used for generating random numbers that need to be secure, such as passwords or security tokens. In those cases, you should use a more secure function, such as random_int from PHP's random_compat library.
