Solved Centered Popups

the text in the photo is that:

PHP:

Player->sendPopup("§a§lExample§r\n§bof a popup not centered");

to make it centered i need to add spaces like:

PHP:

Player->sendPopup("§a§l        Example§r\n§bof a popup not centered");

the problem is that the text can change so, i can't decide how many spaces to add.

I tryed with strlen() to count the text lenght... example:

PHP:

$line1 = 'a text that can change';
$line2 = 'another text that can change';
$len1 = strlen($line1);//22 in this case
$len2 = strlen($line2);//28 in this case

$spacesToAdd = floor(((max($len1, $len2) - min($len1, $len2))/2));
// 28 - 22 = 6 ; 6/2 = 3 ; floor(3) = 3 . so i need to add 3 spaces before the $line1

//to add these spaces i'm using a for loop like: $line1 = ' '.$line1; repeated for 3 times (in this case)  ... another way?

But is not working (not centered text)
Can someone help me please? sorry if my english is not good.

I meant the alignment

no one can help?

I personally think calculating the spaces depending on the strlen is the only way...

and i think i'm doing it in the right way

Player->sendPopup("§a§l Example");
Player->sendPopup("§a§l§ bof a popup not centered");

You use this code

He wants 2 lines and that would just override the previous popup

2 lines is add space in message

solved... is working but if the number is odd , /2 with floor ... there is an half space error , sorry for my bad english, idk how to explain it better

-_-' pls stop replying if you don't understand what i need btw , i solved !

So... Sorry for bumping, but what was your solution?

This works poorly because it does not consider different lengths in each character.

Using str_pad():

PHP:

function alighStringCenter(string $string){
  $strlen = function_exists("mb_strlen") ? "mb_strlen" : "strlen";
  $lines = explode("\n", $string);
  $maxLength = max(array_map($strlen, $lines));
  foreach($lines as &$line){
    $line = str_pad($line, $maxLength, " ", STR_PAD_BOTH);
  }
  return implode("\n", $lines);
}

However, str_pad() is not compatible with multibyte. So your lines will be unreasonably biased if you have Unicode characters there.

Using str_repeat():

PHP:

function alighStringCenter(string $string){
  $strlen = function_exists("mb_strlen") ? "mb_strlen" : "strlen";
  $lines = explode("\n", $string);
  $maxLength = max(array_map($strlen, $lines));
  foreach($lines as &$line){
    $delta = (int) (($maxLength - $strlen($line)) / 2);
    if($delta > 0)
      $line = str_repeat(" ", $delta);
    }
  }
  return implode("\n", $lines);
}

This checks the line of the string with $strlen, which is the function mb_strlen(), or just strlen() if the multibyte extension is not loaded.
