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。我试过了，str_repeat ($output , $password_amount )但后来我得到了两次相同的密码，当我想要 2 个密码（例如 123abc123abc）时，我的输出字段看起来像这样。我是初学者。我愿意接受任何改进和指导。<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html><head><title>Passwort Generator/Tester | </title><meta http-equiv="Content-Type" content="text/html"charset="utf-8"/><link rel="stylesheet" type="text/css" href="PasswortStyle.css" /><link rel="shortcut icon" href="Logo.ico"/><img class="logo" src="logo.png" alt="Logo"/><script> function myFunction() { var copyText = document.getElementById("password"); copyText.select(); copyText.setSelectionRange(0, 99999); document.execCommand("copy");}</script></head><body><h1 id="firstHeading">Passwort-Generator</h1><div class="passwordgen"><?php $numbs = array("0","1","2", "3","4","5","6","7","8","9","@","!","$", "%","&","?",",",".","-",":","_","#","+","*","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); $password_amount = 1; if (isset ($_POST['amount']) ) $password_amount = ($_POST['amount']) ; $password_length = 10; if (isset ($_POST['lenght']) ) $password_length = ($_POST['lenght']) ; $output = ""; for($i=0;$i<$password_length;$i++){ $output .= $numbs[array_rand($numbs)];}

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;
}
并称之为：
$passwords = [];
for($i=0;$i<=$_POST["amount"]-1;$i++) // Repeat generating desired number of times
$passwords[] = generatePassword($_POST["length"]);
var_dump($passwords); //This is the array of your passwords
编辑：根据您的要求，这是将其合并到代码中的方式：
<?php
function generatePassword($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/>
".$message."
</center>";
}
}
?>
这将生成所需数量的密码，根据您的正则表达式检查它们是否有效并按照您的方式打印它们。您只需要替换$amount_of_passwords为所需的数字或让用户在表单中选择，然后将其作为$_POST["amount"]示例传递。
