The Vasu's solution doesn't work well if $pad_string contains multibyte characters.
Here another way to implement it:
<?php
function mb_str_pad($input, $pad_length, $pad_string=' ', $pad_type=STR_PAD_RIGHT) {
$diff = $pad_length - mb_strlen($input, 'UTF-8');
if ($diff <= 0) {
return $input;
}
$pad_string = str_pad($pad_string, 1);
$multiplier = ceil($diff / mb_strlen($pad_string, 'UTF-8'));
$compl = mb_substr(str_repeat($pad_string, $multiplier), 0, $diff, 'UTF-8');
if ($pad_type === STR_PAD_LEFT) {
return $compl.$input;
} elseif ($pad_type === STR_PAD_BOTH) {
return mb_substr($compl, -1, round($diff/2), 'UTF-8')
.$input
.mb_substr($compl, 0, ceil($diff/2), 'UTF-8');
} else {
return $input.$compl;
}
}
echo mb_str_pad('ë', 4, 'éè', STR_PAD_BOTH); // éëéè
?>
