如何添加用户可以决定他想要多少个密码的功能？ [关闭]答案

【问题描述】：

我为我的公司制作了一个密码生成器，现在我想添加用户可以决定他想要多少个密码的功能。

我尝试了str_repeat ($output , $password_amount )，但是我两次获得相同的密码，当我想要 2 个密码时，我的输出字段看起来像这样，例如123abc123abc。

我是初学者。我愿意接受任何改进和指导。

【问题讨论】：

“多少个密码”是什么意思？为什么一个用户应该有多个密码？
str_repeat() 函数将字符串重复指定的次数。多次获得相同的密码是正常的..
@Nico Haase 对于其他公司的一些项目，我们需要很多密码，例如当我们为一群人创建帐户时。那么输出 10 个或 100 个密码比只复制一个密码更容易吗？

【解决方案1】：

例如，您可以将生成器声明为函数，然后在循环中多次调用它。

function generatePassword($password_length) {  
    $numbs = array("0","1","2",
    "3","4","5","6","7","8","9","@","!","$",
    "%","&","?",",",".","-",":","_","#","+","*","q","w","e",
    "r","t","z","u","i","o","p","a","s",
    "d","f","g","h","j","k","l","y","x","c","v","b","n","m","Q","W","E",
    "R","T","Z","U","I","O","P","A","S",
    "D","F","G","H","J","K","L","Y","X","C","V","B","N","M");
    shuffle($numbs);
    $output = "";

    for($i=0;$i<$password_length;$i++){
        $output .= $numbs[array_rand($numbs)];
    }
return $output;
}

然后这样称呼它：

$passwords = [];

for($i=0;$i<=$_POST["amount"]-1;$i++) // Repeat generating desired number of times
$passwords[] = generatePassword($_POST["length"]);
var_dump($passwords); //This is the array of your passwords

编辑：应您的要求，这是您将其合并到代码中的方式：

<?php
function generatePassword($password_length) { //Function to generate the password
    $numbs = array("0","1","2",
    "3","4","5","6","7","8","9","@","!","$",
    "%","&","?",",",".","-",":","_","#","+","*","q","w","e",
    "r","t","z","u","i","o","p","a","s",
    "d","f","g","h","j","k","l","y","x","c","v","b","n","m","Q","W","E",
    "R","T","Z","U","I","O","P","A","S",
    "D","F","G","H","J","K","L","Y","X","C","V","B","N","M");
    shuffle($numbs);
    $output = "";

    for($i=0;$i<$password_length;$i++){
        $output .= $numbs[array_rand($numbs)];
    }
    return $output;
}

if(isset($_POST["lenght"]) { // If user submitted a form
    for($i=0;$i<=$amount_of_passwords-1;$i++) { // Repeat generating desired number of times
        $password = generatePassword($_POST["length"]);

//Regex match on $password
if (!preg_match('/^((?=.*?[A-Z])(?=.*?[a-z])(?=.*?\d)|(?=.*?[A-Z])(?=.*?            [a-z])(?=.*?[^a-zA-Z0-9])|(?=.*?[A-Z])(?=.*?\d)(?=.*?[^a-zA-Z0-9])|(?=.*?[a-z])(?=.*?\d)(?=.*?[^a-zA-Z0-9])).{8,}$/', $password)){   #  (1,2,3|1,2,4|1,3,4|2,3,4) 4 mögliche Kombinationen
$message = "<span style=\"color:red\">Das Passwort entspricht nicht den <a style=\"color:red; text-decoration:underline;\" href=\"http://Passwortrichtlinien\">SKOPOS-Richtlinien</a></span>";
} else{
$message = "<span style=\"color:green\">Das Passwort entspricht den <a style=\"color:green; text-decoration:underline;\" href=\"http://Passwortrichtlinien\">SKOPOS-Richtlinien</a></span>";
}

$size = round($_POST["lenght"] * 1.2);
echo"<center>Zufälliges Passwort:<input type = \"text\" id= \"password\" value=\"".$password."\" size=\"".$size."\" style=\"font-size:16pt; text-align:center; margin: 17px; font-family=\"Monaco, monospace;\" \" /><br/>
".$message."
</center>";
    }
}
?>

这将生成所需数量的密码，根据您的正则表达式检查它们是否有效并按照您所做的那样打印它们。您只需要将$amount_of_passwords 替换为所需的数字，或者让用户在表单中选择，然后将其传递为$_POST["amount"]。

好的，谢谢，我认为这将解决我的问题，但我如何将您的代码包含在我的代码中？我试图包含它，但我不明白。
