在PHP中剪切UTF8文本 [英] Cut an UTF8 text in PHP
问题描述
我从数据库中获取UTF8文本,并且我只想显示前$ len个字符(用一个词整理).我尝试了几个选项,但是由于特殊字符(á,é,í,ó等),该功能仍然无法正常工作.
I get UTF8 text from a database, and I want to show only the first $len characters (finishing in a word). I've tried several options but the function still doesn't work because of special characters (á, é, í, ó, etc).
感谢您的帮助!
function text_limit($text, $len, $end='...')
{
mb_internal_encoding('UTF-8');
if( (mb_strlen($text, 'UTF-8') > $len) ) {
$text = mb_substr($text, 0, $len, 'UTF-8');
$text = mb_substr($text, 0, mb_strrpos($text," ", 'UTF-8'), 'UTF-8');
...
}
}
编辑以添加示例
如果我截断65个字符的文本,它将返回:
If I truncate a text with 65 characters, it returns:
联合国新闻和发展委员会…
Un jardín de estilo neoclásico acorde con el …
如果我更改特殊字符(í,á),则返回:
If I change the special characters (í, á), then it returns:
新古典主义的法国花园……帕拉西奥德……
Un jardin de estilo neoclasico acorde con el Palacio de …
我确定编码,服务器或php有点奇怪;但我不知道!谢谢!
I'm sure there is something strange with the encoding or the server, or php; but I can't figure it out! Thanks!
最终解决方案
我正在使用 UTF8 PHP库现在一切正常...
I'm using this UTF8 PHP library and everything works now...
推荐答案
使用mb_substr.第一个arg要检查的字符串,第二个是起始位置,第三个是长度,最后一个是编码.
use mb_substr. first arg the string to check second is the starting position the third is lenght and last is the encoding.
mb_substr ("String", 0, $len, 'utf-8');
