You can generate random passwords, texts, etc. in any length with this code.
function generate_random_text($length = 3) { // Character list will be used in generating text $characters = 'abcdefghijklmnoprstuvyzxqwABCDEFGHIJKLMNOPRSTUVYZXQW0123456789'; // split character string to character array $character_array = str_split($characters); $text = ''; // choose random character from $character_array and generate string for ($i=0; $i < $length; $i++) { $text .= $character_array[mt_rand(0, strlen($characters) - 1)]; } return $text; } echo generate_random_text(5); // j4SaQ
