Q. PHP: split a UTF-8 string into characters
A.
// Split a UTF-8 string to characters
function utf8Split(string $str): array {
return preg_split('//u', $str, null, PREG_SPLIT_NO_EMPTY);
}
// See if a string has accented letters or other non-ASCII chars
function hasMultibyteChars(string $str): bool {
$charArray = utf8Split($str) {
$len = count($charArray);
for ($i = 0; $i < $len; $i++) {
$char = $charArray[$i];
if (strlen($char) > 1) return true;
}
return false;
}
This is better than using the multibyte functions.
Don't forget to add
<meta charset="UTF-8">
to your page.
