PHP random string

Python has a random package, which can be implemented, such as a random string. php does not. Therefore, you have implemented a functiongenRandomString ($ len) {$ charsarray (a, B, c, d, e, f, g, h, I, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z, A, B, C, D, E, F, G, h, I,

So I implemented

Function genRandomString ($ len) {$ chars = array ("a", "B", "c", "d", "e", "f", "g ", "h", "I", "j", "k", "l", "m", "n", "o", "p", "q ", "r", "s", "t", "u", "v", "w", "x", "y", "z", "", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K ", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U ", "V", "W", "X", "Y", "Z", "0", "1", "2", "3", "4 ", "5", "6", "7", "8", "9"); $ charsLen = count ($ chars)-1; shuffle ($ chars ); // disrupt the array $ output = ""; for ($ I = 0; $ I <$ len; $ I ++) {$ output. = $ chars [mt_rand (0, $ charsLen)];} return $ output ;}
