java版MD5转换成php版

java代码

public static String encryptMD5_Salt(String content) {
    String resultString = "";
    String appkey = "acdf,kef";
    byte[] a = appkey.getBytes();
    byte[] datSource = content.getBytes();
    byte[] b = new byte[a.length + 4 + datSource.length];
    int i;
    for (i = 0; i 
php代码:
function javaMd5($data) {
   assert(is_array($data));
   $dataString = byteArrayToString($data);
   $hashString = md5($dataString);
   return $hashString;
}
function byteArrayToString($b) {
   assert(is_array($b));
   $asciiString = '';
   for ($i = 0; $i
