我写了这个随机密码脚本，它运行得很好。
尽管我想在下面添加额外的一行，显示随机密码的显象字母表。
实现这一点的最佳方式是什么？
<?php
function random_readable_pwd($length=10){
// the wordlist from which the password gets generated
// (change them as you like)
$words = 'AbbyMallard,AbigailGabble,AbisMal,Abu,Adella,TheAgent,AgentWendyPleakley,Akela,AltheAlligator';
$phonetic = array("a"=>"alfa","b"=>"bravo","c"=>"charlie","d"=>"delta","e"=>"echo","f"=>"foxtrot","g"=>"golf","h"=>"hotel","i"=>"india","j"=>"juliett","k"=>"kilo","l"=>"lima","m"=>"mike","n"=>"november","o"=>"oscar","p"=>"papa","q"=>"quebec","r"=>"romeo","s"=>"sierra","t"=>"tango","u"=>"uniform","v"=>"victor","w"=>"whisky","x"=>"x-ray","y"=>"yankee","z"=>"zulu");
// Split by ",":
$words = explode(',', $words);
if (count($words) == 0){ die('Wordlist is empty!'); }
// Add words while password is smaller than the given length
$pwd = '';
while (strlen($pwd) < $length){
$r = mt_rand(0, count($words)-1);
$pwd .= $words[$r];
}
$num = mt_rand(1, 99);
if ($length > 2){
$pwd = substr($pwd,0,$length-strlen($num)).$num;
} else {
$pwd = substr($pwd, 0, $length);
}
$pass_length = strlen($pwd);
$random_position = rand(0,$pass_length);
$syms = "!@#%^*()-?";
$int = rand(0,9);
$rand_char = $syms[$int];
$pwd = substr_replace($pwd, $rand_char, $random_position, 0);
return $pwd;
}
?>
<html><head><title>Password generator</title></head>
<body><p><?php echo random_readable_pwd(10); ?></p></body>
</html>
E.g输出：
Alt！heAll87
ALFA利马探戈！酒店回声ALFA利马利马8 7
您应该逐个字符地循环生成密码，并以此方式构建一个语音字符串。
例如（根据您的代码和需求进行自定义，底部示例尚未经过测试，但应该会让您了解如何处理它）：
$password = "aBcDefG";
$phonetics = array("a"=>"alfa","b"=>"bravo","c"=>"charlie","d"=>"delta","e"=>"echo","f"=>"foxtrot","g"=>"golf","h"=>"hotel","i"=>"india","j"=>"juliett","k"=>"kilo","l"=>"lima","m"=>"mike","n"=>"november","o"=>"oscar","p"=>"papa","q"=>"quebec","r"=>"romeo","s"=>"sierra","t"=>"tango","u"=>"uniform","v"=>"victor","w"=>"whisky","x"=>"x-ray","y"=>"yankee","z"=>"zulu");
$phonetic = array();
for ($i = 0; $i < strlen($password); $i++) {
$char = substr($password, $i, 1);
$phonetic[] = (ctype_upper($char) ? strtoupper(strtr(strtolower($char), $phonetics)) : strtolower(strtr($char, $phonetics)));
}
$phonetic = join(' ', $phonetic);
echo $phonetic;
EDIT我的代码有问题，我更新并测试了它。输出为：alfa BRAVO charlie DELTA echo foxtrot GOLF
