将Java方法Base64.encodeToString（）转换为PHP

Question

Hello I have the below java code:

Base64.encodeToString(("users name").getBytes(), 2);

And I'm trying to convert it to php:

bytesEnc("users name");

function bytesEnc($string) {
    $bytes = array();
    for($i = 0; $i < strlen($string); $i++){
        $bytes[] = ord($string[$i]);
    }
    return $bytes;
}

I converted getBytes() but I don't know what to do next. I know function base64_encode exists inn PHP but the second argument of encodetoString java method with value 2 bothers me. Please, help.

Answer 1

According to the docs the second parameter is a bitwise flag.

If the value is 2, then the flag NO_WRAP is used:

Encoder flag bit to omit all line terminators (i.e., the output will be on one long line).

This means its removes the new lines.

function bytesEnc($string){
  $string = str_replace(PHP_EOL, '', $string);

  $bytes = array();
  for($i = 0; $i < strlen($string) - 1; $i++){
    $bytes[] = ord($string[$i]);
  }
  return $bytes;
}

echo base64_encode(implode('',bytesEnc('users name')));
