Laravel String Helper Function: random

By John Koster

The random helper method generates a random string of the specified $length. This method internally uses the OpenSSL function openssl_random_pseudo_bytes, and therefore requires the OpenSSL extension to be installed and configured.

The signature for the random helper method is:

random($length = 16)

#RuntimeException

A RuntimeException will be thrown if a call is made to random without the OpenSSL extension installed.

It should also be noted that the random method remove the following characters:
/ + =

The following examples show sample output. Because the intention of the random method is to generate a random string, any output you get will likely be different:

 1use Illuminate\Support\Str;

 2

 3// XHJtXFOa5Jt8B48z

 4echo Str::random();

 5

 6// z50fdgeBrmoJRBh7

 7echo Str::random();

 8

 9// 2bXJNUcZVdtZfUUzbEgfvvaawOCfOgvK

10echo Str::random(32);

#str_random($length = 16)

The str_random function is a shortcut to calling Str::random. This function is declared in the global namespace.
