本文实例讲述了php简单截取字符串的方法。分享给大家供大家参考，具体如下：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 //截取摘要 public static function mbsubstr($str){ $strleng = mb_strlen($str,"utf8"); $mbstr = mb_substr($str,0,140,'utf8'); $strdstr = mb_substr($str,140,$strleng,'utf8'); $strlengs = mb_strlen($strdstr,'utf8'); $strc = ""; for($i=0;$i<$strlengs;$i++){ $strn = mb_substr($strdstr,$i,1,'utf8'); if($strn == "。" || $strn == "？" || $strn == "！"){ break; } $strc .= $strn; } $strd = $mbstr.$strc; //echo $strleng."@".mb_strlen($strd,'utf8')."@".$strd."<br>"; return $strd; }

希望本文所述对大家PHP程序设计有所帮助。
