//The getRandomword = 7 is the number of characters

function getRandomWord($len = 7) {

//O array_merge = this case will be a combination of the z

$word = array_merge(range('a', 'z'), range('A', 'Z'));
shuffle($word);
return substr(implode($word), 0, $len);
}

//O 1000 = this case is the number of repetitions, here we have to make some calculations combinatorics not to repeat combinations. Eg you put $ len = 2 and 'a', 'c' is the number of repetitions equal to "6" = ab, ba, ca, ac, cb, bc or 2 * 3 = 6

for ($i = 0; $i < 1000; $i++) {
echo getRandomWord()."<p>";
