如何在php中编码和解码多维数组？

Question

可能重复：
PHP array Encoding and Decoding:Need a function for encoding and decoding string or array with delimiters or array itself…

喜。 我是新来的PHP。 我需要编写两个单独的函数编码和解码多维数组在php中。 我附上一个插件.......... encode.class.php ..............

从这个插件，我需要使用我的函数中的编码和解码函数用于模式检查。 如果有人能帮助我.......这会是很好的me.coz我需要它........

Answer 1

使用serialize()和unserialize()打开数组到字符串和回到阵列（除了资源以外的其他所有东西都可以）

Answer 2

看起来像一个非常大的编码器/解码器类。

也许这RC4算法会更容易

//encrypt 
$encrypted = RC4Crypt::encrypt('your key','some string to encrypt'); 

//decrypt 
$decrypted = RC4Crypt::encrypt('your key',$encrypted); 

//The RC4 Class 
class RC4Crypt { 
    function encrypt ($pwd, $data){ 
     $key[] = ''; 
     $box[] = ''; 
     $pwd_length = strlen($pwd); 
     $data_length = strlen($data); 
     for ($i = 0; $i < 256; $i++){ 
      $key[$i] = ord($pwd[$i % $pwd_length]); 
      $box[$i] = $i; 
     } 
     for ($j = $i = 0; $i < 256; $i++){ 
      $j = ($j + $box[$i] + $key[$i]) % 256; 
      $tmp = $box[$i]; 
      $box[$i] = $box[$j]; 
      $box[$j] = $tmp; 
     } 
     $cipher = ''; 
     for ($a = $j = $i = 0; $i < $data_length; $i++){ 
      $a = ($a + 1) % 256; 
      $j = ($j + $box[$a]) % 256; 
      $tmp = $box[$a]; 
      $box[$a] = $box[$j]; 
      $box[$j] = $tmp; 
      $k = $box[(($box[$a] + $box[$j]) % 256)]; 
      $cipher .= chr(ord($data[$i])^$k); 
     } 
     return ($cipher); 
    } 
    function decrypt ($pwd, $data){ 
     return RC4Crypt::encrypt($pwd, ($data)); 
    } 
}
