导读： _tags($string, $replace_with_space = true)
{
if ($replace_with_space) {
return preg_replace('!]*?>!', ' ', $string);
} else {
return strip_t
{
if ($replace_with_space) {
return preg_replace('!]*?>!', ' ', $string);
} else {
return strip_t

_tags($string, $replace_with_space = true) { if ($replace_with_space) { return preg_replace('!]*?>!', ' ', $string); } else { return strip_tags($string); } } 截取字符函数（匹配各种编码） function truncate($string, $length = 80, $etc = '...', $break_words = false, $middle = false){ if ($length == 0) return ''; if (is_callable('mb_strlen')) { if (mb_detect_encoding($string, 'UTF-8, ISO-8859-1') === 'UTF-8') { // $string has utf-8 encoding if (mb_strlen($string) > $length) { $length -= min($length, mb_strlen($etc)); if (!$break_words && !$middle) { $string = preg_replace('/\s+?(\S+)?$/u', '', mb_substr($string, 0, $length + 1)); } if (!$middle) { return mb_substr($string, 0, $length) . $etc; } else { return mb_substr($string, 0, $length / 2) . $etc . mb_substr($string,- $length / 2); } } else { return $string; } } } // $string has no utf-8 encoding if (strlen($string) > $length) { $length -= min($lengthphp代码, strlen($etc)); if (!$break_words && !$middle) { $string = preg_replace('/\s+?(\S+)?$/', '', substr($string, 0, $length + 1)); } if (!$middle) { return substr($string, 0, $length) . $etc; } else { return substr($string, 0, $length / 2) . $etc . substr($string, - $length / 2); } } else { return $string; } } 综合就是 $arc=strip_tags($arc); $arc=truncate($arc,200) （编辑：我爱资讯网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
