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;
}

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);

另一个(仅限linux)
function randompassword()
{
$fp = fopen ("/dev/urandom", 'r');
if (!$fp) { die ("Can't access /dev/urandom to get random data. Aborting."); }
$random = fread ($fp, 1024); # 1024 bytes should be enough
fclose ($fp);
return trim (base64_encode ( md5 ($random, true)), "=");
}
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); } } ?>

一个简单的代码应该是这样的:
function generatePassword($len){
$az = range("a","z");
$AZ = range("A","Z");
$num = range(0,9);
$password = array_merge($az,$AZ,$num);
return substr(str_shuffle(implode("",$password)),0, $len);
}
// testing
$generate = range(8,32);
foreach($generate as $g){
print "Len:{$g} = " . generatePassword($g)."\n";
}
输出:
Len:8 = G5uFhPKS
Len:9 = aU9x2NjvI
Len:10 = lJE9kxy3oD
Len:11 = tVh2CmpMdHW
Len:12 = ToXYHCPb58Ar

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;”
