Add the following code to the Common directory in the project directory. php files, such as www/Common/common. php file, of course, you can also directly add it to the Common/common of thinkphp. in the php file, all projects can be used.

Function truncate_cn ($ string, $ length = 0, $ ellipsis = '... ', $ Start = 0) {$ string = strip_tags ($ string); $ string = preg_replace ('/\ n/is ', '', $ string ); // $ string = preg_replace ('/|/is', ', $ string); // clear the spaces in the string $ string = preg_replace (' // is ', '', $ string ); preg_match_all ("/[\ x01-\ x7f] | [\ xc2-\ xdf] [\ x80-\ xbf] | \ xe0 [\ xa0-\ xbf] [\ x80- \ xbf] | [\ xe1-\ xef] [\ x80-\ xbf] [\ x80-\ xbf] | \ xf0 [\ x90-\ xbf] [\ x80 -\ xbf] [\ x80-\ xbf] | [\ xf1-\ xf7] [\ x80-\ xbf] [\ x80-\ xbf] [\ x80-\ xbf]/", $ string, $ string); if (is_a Rray ($ string )&&!
