Laravel String Helper Function: random

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)

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.
