PHP array contains both Chinese and English, how to sort the first word or Chinese characters

PHP has a lot of functions for sorting arrays.

For example, the most basic sort and rsort (plus r The representative reverse order, the same below);
The natural sort natsort (natural sort is to sort the numbers by size, not by ASCII code) and ignore the case natcasesort ;
Keep the key-value index relationship asort arsort ;
The and of the sort according to the key ksort krsort ;
If you are not satisfied with the built-in collation, you can also write your own function to determine the collation usort , uasort and uksort (the corresponding function does not have u the above);
There is also the ability to sort multiple arrays and keep only the key-value index relationships of the associated array array_multisort .

There is always one for you in so many sorts.
Please refer to the documentation for details.

Using the strcmp string to compare the ordering has actually been able to meet your needs.
STRNATCMP Natural Sort and strcmp string comparison sort the main difference is that the numbers, strnatcmp processed by the number elements are from small to large sort, there is a size relationship.
In the ICU Extension Intl, the Simplified Chinese sequencer collator_sort (ZH_CN) sorting is mainly based on the pinyin of the Chinese characters, such as Ali,baidu,zhongguo. Interested can also see my article PHP uses ICU Extension Intl To quickly implement Chinese characters to pinyin and to sort alphabetically by the first letter of Pinyin, Chinese characters to Pinyin is a function of things:

echo transliterator_transliterate('Any-Latin; Latin-ASCII; Upper()', '中华有为');//输出 ZHONG HUA YOU WEI
