我在php的加密代码错误

-3

请问我的代码可能有什么问题？该代码旨在加密给定的字符串。它的加密完全没问题，但是当回显加密的值时，它会给它添加数字。下面是代码：我在php的加密代码错误

$keys = "Bb94tU1LSSLgPKNu"; 
$encrypt = array(); 

// this contains the key/value pair i used for the encryption 
$arrayEncrypt = array("a"=>"g","b"=>"h","c"=>"i","d"=>"j","e"=>"k","f"=>"l","g"=>"m","h"=>"n","i"=>"o","j"=>"p","k"=>"q","l"=>"r", "m"=>"s","n"=>"t","o"=>"u","p"=>"v","q"=>"w","r"=>"x","s"=>"y","t"=>"z","u"=>"a","v"=>"b","w"=>"c","x"=>"d","y"=>"e","z"=>"f","A"=>"G","B"=>"H","C"=>"I","D"=>"J","E"=>"K","F"=>"L","G"=>"M","H"=>"N","I"=>"O","J"=>"P","K"=>"Q","L"=>"R","M"=>"S","N"=>"T","O"=>"U","P"=>"V","Q"=>"W","R"=>"X","S"=>"Y","T"=>"Z","U"=>"A","V"=>"B","W"=>"C","X"=>"D","Y"=>"E","Z"=>"F","0"=>"2","1"=>"4","2"=>"6","3"=>"8","4"=>"0","5"=>"9","6"=>"7","7"=>"5","8"=>"3","9"=>"1"); 

for ($i = 0; $i < strlen($keys); $i++) { 
    if (array_key_exists($keys[$i], $arrayEncrypt)) { 
     foreach ($arrayEncrypt as $key => $letter) { 
      if ($keys[$i] == $key) { 
       // appends the values of each in $encrypt array 
       array_push($encrypt, $letter); 
      } 
     } 
    } 
} 

$encryptedValue = ""; 
foreach ($encrypt as $encrypted) { 
    $encryptedValue .= $encrypted; 
    echo $encryptedValue; 
}

它打印：

H2h210z2A24R2Y2Y2R2m2V2Q2T2a2

相反的：

Hh10zA4RYYRmVQTa

此代码甚至不起作用。除了你错过分号和做''$ encryptedValue = ...'之类的事实，当我纠正它们时，它不会产生任何输出。 – Enstage

请不要对非js，css或html代码使用片段功能。 – Daedalus

@Enstage我粘贴了完整的代码并更正了您提到的那一行。你现在可以检查一下吗？ – Nathileo

在任何情况下，你是在复杂它试图使用$我，而不是只使用名称来获得匹配值。 str_split（）获取一个字符数组，然后它只是$ arrayEncrypt [$ value]的问题。要撤消你可以使用array_flip（）。

为您提供了一个很好的加密和解密功能。享受

<?php 
// 1 to encrypt 
// 2 to decrypt 
function encdec($do, $keys){ 
    $arrayEncrypt = array("a"=>"g","b"=>"h","c"=>"i","d"=>"j","e"=>"k","f"=>"l","g"=>"m","h"=>"n","i"=>"o","j"=>"p","k"=>"q","l"=>"r", "m"=>"s","n"=>"t","o"=>"u","p"=>"v","q"=>"w","r"=>"x","s"=>"y","t"=>"z","u"=>"a","v"=>"b","w"=>"c","x"=>"d","y"=>"e","z"=>"f","A"=>"G","B"=>"H","C"=>"I","D"=>"J","E"=>"K","F"=>"L","G"=>"M","H"=>"N","I"=>"O","J"=>"P","K"=>"Q","L"=>"R","M"=>"S","N"=>"T","O"=>"U","P"=>"V","Q"=>"W","R"=>"X","S"=>"Y","T"=>"Z","U"=>"A","V"=>"B","W"=>"C","X"=>"D","Y"=>"E","Z"=>"F","0"=>"2","1"=>"4","2"=>"6","3"=>"8","4"=>"0","5"=>"9","6"=>"7","7"=>"5","8"=>"3","9"=>"1"); 

    if ($do==2){ 
     $arrayEncrypt=array_flip($arrayEncrypt); 
    } 

    $chars = str_split($keys); 
    $encryptedValue=""; 

    foreach($chars as $char=>$value){ 
     $encryptedValue .= $arrayEncrypt[$value]; 
    } 

    return $encryptedValue; 
} 

echo "Encrypted key: ".encdec(1,"Bb94tU1LSSLgPKNu")."<br />"; 
echo "Decrypted key: ".encdec(2,"Hh10zA4RYYRmVQTa")."<br />"; 

?>

它的工作。谢谢@帕特里克。我只是PHP的初学者。我用这个答案了解了一些新东西 – Nathileo
