平时用我们使用htmlspecialchars() 来过滤html, 但是把html的字符转义了,最后显示出来的就是html源代码.

利用strip_tags()就可以把html标签去除掉.

$str = 'href';
//echo htmlspecialchars($str);
echo strip_tags($str);

?>

很多网站首页都有一片文章的一小部分.在这里就要使用strip_tags()把html标签去除掉.但但是汉字的话我们还要考虑是什么编码,因为正常切割字段串很容易把最后一个汉字切成一半.

/**
* 截取utf-8字符串
* @since 2008.12.23
* @param string $str 被截取的字符串
* @param integer $start 起始位置
* @param integer $length 截取长度(每个汉字为3字节)
*/
function utf8_strcut($str, $start, $length=null) {
preg_match_all('/./us', $str, $match);
$chars = is_null($length)? array_slice($match[0], $start ) : array_slice($match[0], $start, $length);

unset($str);

return implode('', $chars);
}
