这篇文章主要介绍了PHP生成随机密码类分享,生成的密码包含大小写英文字母及数字,需要的朋友可以参考下

类代码:

length = $length; $this->configure(true, true, true, false, false); } /** * 配置 */ function configure($uppercase = false, $lowercase = false, $number = false, $special = false, $extra = false ) { $this->chars = array(); $this->upper_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" ); $this->lower_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" ); $this->number_chars = array( "1", "2", "3", "4", "5", "6", "7", "8", "9", "0" ); $this->special_chars = array( "!", "@", "#", "$", "%", "^", "&", "*", "(", ")" ); $this->extra_chars = array( "[", "]", "{", "}", "-", "_", "+", "=", "", "?", "/", "`", "~", "|", ",", ".", ";", ":" ); if (($this->uppercase = $uppercase) === true) { $this->chars = array_merge($this->chars, $this->upper_chars); } if (($this->lowercase = $lowercase) === true) { $this->chars = array_merge($this->chars, $this->lower_chars); } if (($this->number = $number) === true) { $this->chars = array_merge($this->chars, $this->number_chars); } if (($this->special = $special) === true) { $this->chars = array_merge($this->chars, $this->special_chars); } if (($this->extra = $extra) === true) { $this->chars = array_merge($this->chars, $this->extra_chars); } $this->chars = array_unique($this->chars); } /** * 从字符列中生成随机密码 * * @return string **/ function generate() { if (empty($this->chars)) { return false; } $hash = ''; $totalChars = count($this->chars) - 1; for ($i = 0; $i length; $i++) { $hash .= $this->chars[$this->random(0, $totalChars)]; } return $hash; } /** * 生成随机数字 * * @return int */ function random($min = 0, $max = 0) { $max_random = 4294967295; $random = uniqid(microtime() . mt_rand(), true); $random = sha1(md5($random)); $value = substr($random, 0, 8); $value = abs(hexdec($value)); if ($max != 0) { $value = $min + ($max - $min + 1) * $value / ($max_random + 1); } return abs(intval($value)); } }

调用:
