How to get 8 first and last from php var (utf-8)?

Question

How to get 8 first and last from php var (utf-8) ?

I tried this code but not show 8 first and last.

<?PHP
$file_name= "Μια φορά κι έναν καιρό";

$first_8_char_file_name_display = mb_substr($file_name, 0, 8, "utf-8");
$last_8_char_file_name_display = mb_substr($file_name ,-8, "utf-8");

echo $first_8_char_file_name_display;
echo "<BR>";
echo $last_8_char_file_name_display;
?>

How can i do that ?

try using `mb_substr` instead of `substr` - it is multi-byte safe. — DerVO, Feb 18 '16 at 13:32

Try to do this:

$file_name= "Μια φορά κι έναν καιρό";
$from = strlen($file_name)/2-6;
$first_8_char_file_name_display = mb_substr($file_name, 0, 8,"utf-8");
$last_8_char_file_name_display = mb_substr($file_name, $from, 8,"utf-8");

echo $from;
echo "<br/>";
echo $first_8_char_file_name_display;
echo "<br/>";
echo $last_8_char_file_name_display;

You can try using mb_substr instead, as it supports multi-byte strings:

$first_8_char_file_name_display = mbsubstr($file_name, 0, 8);
$last_8_char_file_name_display = mbsubstr($file_name, -8);

For single-byte strings (e.g. US-ASCII, ISO 8859 family, etc.) use substr.

For multi-byte strings (e.g. UTF-8, UTF-16, etc.) use mb_substr
