php数组如何按拼音顺序排序

php$pinyin = array(
        array('name'=>'梁朝伟','age'=>23),
        array('name'=>'andy','age'=>24),
        array('name'=>'黎明','age'=>19),
        array('name'=>'郭富城','age'=>20)
    );

name字段转为拼音然后按字母排序，如果第一个字母相同比较第二个，希望结果为

php$pinyin = array(
        array('name'=>'andy','age'=>24),
        array('name'=>'郭富城','age'=>20)
        array('name'=>'梁朝伟','age'=>23),
        array('name'=>'黎明','age'=>19),
    );

找到汉字转拼音库

不懂楼主的做法，汉字排序时本来就是按拼音顺序排的，因为汉字编码表本身就是按照字母顺序来的。echo "梁朝伟" < "黎明" 得到true
拼音排序还要用拼音库的都太缺乏基础知识了。

@incNick 其实GBK编码也不是完全按照首字母排序的，你可以去查一查GBK编码表，希望大家不要被误导

楼上正解，手册看一下array_multisort()

---

$sort = array();
foreach($pinyin as $key => $item) {
    $py = zhcnToPinyin($item['name']);
    $pinyin[$key]['pinyin'] = $py;
    $sort[] = $py;
}

array_multisort($sort, SORT_ASC, $pinyin);

function zhcnToPinyin() {
   //TODO 汉字转拼音
}

最近也碰到了要对汉字排序的问题, Collator 效果还不错, 参考 Comparing UTF-8 String

$name = [...];
(new \Collator('zh-CN'))->asort($name);
var_dump( $name );
