任何人都遇到复杂的拉丁字符,如越南语?
function truncate($str, $length, $append = '…') {
$strLength = mb_strlen($str);
if ($strLength <= $length) {
return $str;
}
return mb_substr($str, 0, $length) . $append;
}
echo truncate('Bà Rịa - Vũng Tàu!', 14);
输出:
BàRịa – V ……

我需要一些帮助来削减角色,但我甚至不确定幕后发生了什么.
最佳答案 您可以使用
mb_strimwidth(PHP文档):
echo mb_strimwidth("Hello World", 0, 10, "...");
或者像Multibyte String Truncate for Smarty这样的自定义功能:
mb_truncate($string, $length = 80, $etc = '...', $charset='UTF-8',
$break_words = false, $middle = false)
{
if ($length == 0)
return '';
if (strlen($string) > $length) {
$length -= min($length, strlen($etc));
if (!$break_words && !$middle) {
$string = preg_replace('/\s+?(\S+)?$/', '', mb_substr($string, 0, $length+1, $charset));
}
if(!$middle) {
return mb_substr($string, 0, $length, $charset) . $etc;
} else {
return mb_substr($string, 0, $length/2, $charset) . $etc . mb_substr($string, -$length/2, $charset);
}
} else {
return $string;
}
}
