以下是我对选项列表的贡献。

该功能可以确保密码策略被满足。

  function password_generate($length=8, $min_lowercases=1, $min_uppercases=1, $min_numbers=1, $min_specials=0) {

    $lowercases = 'abcdefghijklmnopqrstuvwxyz';
    $uppercases = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $numbers = '0123456789';
    $specials = '!#%&/(){}[]+-';

    $absolutes = '';
    if ($min_lowercases && !is_bool($min_lowercases)) $absolutes .= substr(str_shuffle(str_repeat($lowercases, $min_lowercases)), 0, $min_lowercases);
    if ($min_uppercases && !is_bool($min_uppercases)) $absolutes .= substr(str_shuffle(str_repeat($uppercases, $min_uppercases)), 0, $min_uppercases);
    if ($min_numbers && !is_bool($min_numbers)) $absolutes .= substr(str_shuffle(str_repeat($numbers, $min_numbers)), 0, $min_numbers);
    if ($min_specials && !is_bool($min_specials)) $absolutes .= substr(str_shuffle(str_repeat($specials, $min_specials)), 0, $min_specials);

    $remaining = $length - strlen($absolutes);

    $characters = '';
    if ($min_lowercases !== false) $characters .= substr(str_shuffle(str_repeat($lowercases, $remaining)), 0, $remaining);
    if ($min_uppercases !== false) $characters .= substr(str_shuffle(str_repeat($uppercases, $remaining)), 0, $remaining);
    if ($min_numbers !== false) $characters .= substr(str_shuffle(str_repeat($numbers, $remaining)), 0, $remaining);
    if ($min_specials !== false) $characters .= substr(str_shuffle(str_repeat($specials, $remaining)), 0, $remaining);

    $password = str_shuffle($absolutes . substr($characters, 0, $remaining));

    return $password;
  }

参数$min_*可以有以下值:

1-999 =需要 True =可选 False =禁用

它可以像下面这样使用:

echo password_generate(8); // Outputs a random 8 characters long password

10个字符的密码，每组至少有2个字符:

echo password_generate(10, 2, 2, 2, 2);

只输出6个随机数

echo password_generate(6, false, false, true, false);

Create a file with this code in it. Call it like in the comments. <?php /** * @usage : * include_once($path . '/Password.php'); * $Password = new Password; * $pwd = $Password->createPassword(10); * return $pwd; * */ class Password { public function createPassword($length = 15) { $response = []; $response['pwd'] = $this->generate($length); $response['hashPwd'] = $this->hashPwd( $response['pwd'] ); return $response; } private function generate($length = 15) { $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*(){}/?,><"; return substr(str_shuffle($chars),0,$length); } private function hashPwd($pwd) { return hash('sha256', $pwd); } } ?>

下面是另一个密码生成器代码片段。 控制长度，数字和特殊字符计数和列表。

其他解决方案的一个问题是，它们没有包含重复字符的选项。而下面的脚本也可以做到这一点。

$length = random_int(30, 40);

$pass = [];

$lowers = range('a', 'z');
$uppers = range('A', 'Z');
$digits = range('0', '9');
$specials = ['.', '-', '_', '^', '#', '(', ')'];

$specialCount = random_int(1, 5);
$digitCount = random_int(1, 9);

for ($i = 0; $i < $length - $specialCount - $digitCount; $i++) { 
    $pass[] = random_int(1, PHP_INT_MAX) % 2 == 0 ? $uppers[array_rand($uppers)] : $lowers[array_rand($lowers)];
}
for ($i = 0; $i < $specialCount; $i++) { 
    $pass[] = $specials[array_rand($specials)];
}
for ($i = 0; $i < $digitCount; $i++) { 
    $pass[] = $digits[array_rand($digits)];
}

shuffle($pass)

$pass = implode('', $pass);

Generates a strong password of length 8 containing at least one lower case letter, one uppercase letter, one digit, and one special character. You can change the length in the code too. function checkForCharacterCondition($string) { return (bool) preg_match('/(?=.*([A-Z]))(?=.*([a-z]))(?=.*([0-9]))(?=.*([~`\!@#\$%\^&\*\(\)_\{\}\[\]]))/', $string); } $j = 1; function generate_pass() { global $j; $allowedCharacters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ~`!@#$%^&*()_{}[]'; $pass = ''; $length = 8; $max = mb_strlen($allowedCharacters, '8bit') - 1; for ($i = 0; $i < $length; ++$i) { $pass .= $allowedCharacters[random_int(0, $max)]; } if (checkForCharacterCondition($pass)){ return '<br><strong>Selected password: </strong>'.$pass; }else{ echo 'Iteration '.$j.': <strong>'.$pass.'</strong> Rejected<br>'; $j++; return generate_pass(); } } echo generate_pass();

我的答案与上面的一些类似，但我去掉了元音，数字1和0，字母I, j, I, l, O, O, Q, Q, X, X, Y, Y, W, W。原因是:第一个很容易混淆(就像l和1，取决于字体)，其余的(从Q开始)是因为它们在我的语言中不存在，所以对于超级终端用户来说可能有点奇怪。字符串仍然足够长。此外，我知道使用一些特殊的标志是理想的，但他们也与一些最终用户相处不好。

function generatePassword($length = 8) {

$chars = '23456789bcdfhkmnprstvzBCDFHJKLMNPRSTVZ';
$shuffled = str_shuffle($chars);
$result = mb_substr($shuffled, 0, $length);

return $result;
}

此外，通过这种方式，我们避免重复相同的字母和数字(不包括匹配情况)

一句话:

substr(str_shuffle('abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789') , 0 , 10 )
