我试图在php中生成一个随机密码。
但是我得到的都是'a'返回类型是数组类型，我希望它是字符串。对如何修改代码有什么想法吗?
谢谢。
function randomPassword() {
$alphabet = "abcdefghijklmnopqrstuwxyzABCDEFGHIJKLMNOPQRSTUWXYZ0123456789";
for ($i = 0; $i < 8; $i++) {
$n = rand(0, count($alphabet)-1);
$pass[$i] = $alphabet[$n];
}
return $pass;
}
当前回答
有一个简短的解决方案(php 8.1):
$dict = array_merge(
...array_map(
fn(array $d): array => range(ord($d[0]), ord($d[1])),
[["0", "9"], ["a", "z"], ["A", "Z"]]
)
);
$f = fn (int $len): string =>
join(
"",
array_map(
fn (): string => chr($dict[random_int(0, count($dict) - 1)]),
range(0, $len)
)
);
echo $f(12) . PHP_EOL;
一行bash脚本:
PHP -r '$dict = array_merge(…到fn(数组$ d):数组= >范围(奥德($ d[0]),奥德($ d[1])),(“0”,“9”,“一个”、“z”,[“一”、“z”]]));$ f = fn (int len美元):字符串= >加入(“”,到(fn():字符串= >科($ dict [random_int (0, count ($ dict) - 1))),范围(0,len美元)));Echo $f(12)。PHP_EOL;”

其他回答
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('', $pass);
一句话:
substr(str_shuffle('abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789') , 0 , 10 )
function password_generate($n, $l, $s)
{
$numbers = '1234567890';
$letters = '1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcefghijklmnopqrstuvwxyz';
$special = '--!=!@@#++%';
return substr(str_shuffle($numbers), 0, $n).substr(str_shuffle($letters), 0, $l).substr(str_shuffle($special), 0, $s);
}
echo password_generate(2,9,1);
Create a file with this code in it. Call it like in the comments. <?php /** * @usage : * include_once($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); } } ?>
该函数将根据参数中的规则生成密码
function random_password( $length = 8, $characters = true, $numbers = true, $case_sensitive = true, $hash = true ) {
$password = '';
if($characters)
{
$charLength = $length;
if($numbers) $charLength-=2;
if($case_sensitive) $charLength-=2;
if($hash) $charLength-=2;
$chars = "abcdefghijklmnopqrstuvwxyz";
$password.= substr( str_shuffle( $chars ), 0, $charLength );
}
if($numbers)
{
$numbersLength = $length;
if($characters) $numbersLength-=2;
if($case_sensitive) $numbersLength-=2;
if($hash) $numbersLength-=2;
$chars = "0123456789";
$password.= substr( str_shuffle( $chars ), 0, $numbersLength );
}
if($case_sensitive)
{
$UpperCaseLength = $length;
if($characters) $UpperCaseLength-=2;
if($numbers) $UpperCaseLength-=2;
if($hash) $UpperCaseLength-=2;
$chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
$password.= substr( str_shuffle( $chars ), 0, $UpperCaseLength );
}
if($hash)
{
$hashLength = $length;
if($characters) $hashLength-=2;
if($numbers) $hashLength-=2;
if($case_sensitive) $hashLength-=2;
$chars = "!@#$%^&*()_-=+;:,.?";
$password.= substr( str_shuffle( $chars ), 0, $hashLength );
}
$password = str_shuffle( $password );
return $password;
}
