如何用PHP按字符串长度将包含中文的文本分割成数组？

本文共计150个文字，预计阅读时间需要1分钟。

phpfunction str_split_unicode($str, $l=0) { if ($l > 0) { $ret=array(); $len=mb_strlen($str, UTF-8); for ($i=0; $i < $len; $i +=$l) { $ret[]=mb_substr($str, $i, $l, UTF-8); } return $ret; } return preg_split(/u, $str, -1, PREG_SPLIT_NO_EMPTY);}

<?php function str_split_unicode($str, $l = 0) { if ($l > 0) { $ret = array(); $len = mb_strlen($str, "UTF-8"); for ($i = 0; $i < $len; $i += $l) { $ret[] = mb_substr($str, $i, $l, "UTF-8"); } return $ret; } return preg_split("//u", $str, -1, PREG_SPLIT_NO_EMPTY); } ?> $s = "还未如愿sss见gfg者不rtret不朽"; // Mild milk print_r(str_split($s, 5)); print_r(str_split_unicode($s, 5)); //输出 //Array ( [0] => 还�� [1] => �如� [2] => ��sss [3] => 见gf [4] => g者� [5] => ��rtr [6] => et不 [7] => 朽 ) //Array ( [0] => 还未如愿s [1] => ss见gf [2] => g者不rt [3] => ret不朽 ) blog.ppsql.net/post-1843.html
