/*** @param string|null $name* @return array|null*/
function splitName($name)
{if (empty($name) || empty(trim($name))) {return null;}//该正则是用来提取$name参数里面的中文字符的。preg_match_all('/[\x{4e00}-\x{9fff}]+/u', $name, $matchers);$matchersCount = isset($matchers[0]) ? count($matchers[0]) : 0;if ($matchersCount <= 0) {return null;}$firstName = $lastName = '';if ($matchersCount == 1) {$lastName = mb_substr($name, 0, 1);$firstName = mb_substr($name, 1);} else {foreach ($matchers[0] as $index => $value) {if ($index == 0) {$firstName = $value;} else {$lastName .= $value;}}}return compact('firstName', 'lastName');
}var_dump(splitName("姓名"));
var_dump(splitName("姓1231名adsa"));
var_dump(splitName("买买提·吐尔逊"));

测试结果如下：
