php mb_chunk_split函數支援寬字元分割

/** * 分割字串 * @param String $str 要分割的字串 * @param int $length 指定的長度 * @param String $end 在分割後的字串塊追加的內容 */ function mb_chunk_split($string, $length, $end, $once = false){ $string = iconv('gb2312', 'utf-8//ignore', $string); $array = array(); $strlen = mb_strlen($string); while($strlen){ $array[] = mb_substr($string, 0, $length, "utf-8"); if($once) return $array[0] . $end; $string = mb_substr($string, $length, $strlen, "utf-8"); $strlen = mb_strlen($string); } return implode($end, $array); } $str = 's六一馬上$就dfs要到$@#了'; $str1 = 'aabbccddeefff'; echo mb_chunk_split($str, 3, '...', true); //s六一...馬上$...就df...s要到...$@#...了 echo " "; echo mb_chunk_split($str1, 2, '...'); //aa...bb...cc...dd...ee...ff...f 複製代碼
