php使用自定义函数实现汉字分割替换功能示例

header("Content-type:text/html;charset=utf-8");$str="赵钱孙";function mbstringToArray($str,$charset) {  $strlen=mb_strlen($str);  while($strlen){    $array[]=mb_substr($str,0,1,$charset);    $str=mb_substr($str,1,$strlen,$charset);    $strlen=mb_strlen($str);  }  return $array;}//用法gbk utf-8$arr = mbstringToArray($str,"utf-8");var_dump($arr);

array(3) { [0]=> string(2) "赵" [1]=> string(2) "钱" [2]=> string(2) "孙"}
