PHP – iterate on string characters

Use str_split to iterate ASCII strings (since PHP 5.0)

If your string contains only ASCII (i.e. “English”) characters, then use str_split.

$str="some text";
foreach (str_split($str) as $char) {
    var_dump($char);
}

Use mb_str_split to iterate Unicode strings (since PHP 7.4)

If your string might contain Unicode (i.e. “non-English”) characters, then you must use mb_str_split.

$str="μυρτιὲς δὲν θὰ βρῶ";
foreach (mb_str_split($str) as $char) {
    var_dump($char);
}
