An explanation of how the PHP array is sorted by phonetic order

This article mainly introduces the PHP implementation of the array in alphabetical order, involving the conversion of PHP kanji and Pinyin and array traversal, sorting related operations skills, the need for friends can refer to the next

First, the question:

The given array requires implementation to be sorted alphabetically by its kanji:

$pinyin = Array (  ' name ' = ' Tony Leung ', ' age ' =>23),  Array (' name ' = "Andy ', ' age ' =>24),  Array ( ' Name ' = ' Dawn ', ' age ' =>19,  Array (' name ' = ' Aaron Kwok ', ' age ' =>20));

Second, the solution:

<?php/* * Created on 2017-5-3 * author:www.jb51.net * */function Zhcntopinyin ($STR)//kanji to pinyin function {if (empty ($STR)) {return  '';}  $fchar =ord ($str {0});  if ($fchar >=ord (' A ') && $fchar <=ord (' z ')) return Strtoupper ($str {0});  $s 1=iconv (' UTF-8 ', ' gb2312 ', $str);  $s 2=iconv (' gb2312 ', ' UTF-8 ', $s 1);  $s = $s 2== $str? $s 1: $str;  $asc =ord ($s {0}) *256+ord ($s {1})-65536;  if ($asc >=-20319&& $asc <=-20284) return ' A ';  if ($asc >=-20283&& $asc <=-19776) return ' B ';  if ($asc >=-19775&& $asc <=-19219) return ' C ';  if ($asc >=-19218&& $asc <=-18711) return ' D ';  if ($asc >=-18710&& $asc <=-18527) return ' E ';  if ($asc >=-18526&& $asc <=-18240) return ' F ';  if ($asc >=-18239&& $asc <=-17923) return ' G ';  if ($asc >=-17922&& $asc <=-17418) return ' H ';  if ($asc >=-17417&& $asc <=-16475) return ' J ';  if ($asc >=-16474&& $asc <=-16213) return ' K '; if ($asc >=-16212&& $asc <=-15641) return ' L ';  if ($asc >=-15640&& $asc <=-15166) return ' M ';  if ($asc >=-15165&& $asc <=-14923) return ' N ';  if ($asc >=-14922&& $asc <=-14915) return ' O ';  if ($asc >=-14914&& $asc <=-14631) return ' P ';  if ($asc >=-14630&& $asc <=-14150) return ' Q ';  if ($asc >=-14149&& $asc <=-14091) return ' R ';  if ($asc >=-14090&& $asc <=-13319) return ' S ';  if ($asc >=-13318&& $asc <=-12839) return ' T ';  if ($asc >=-12838&& $asc <=-12557) return ' W ';  if ($asc >=-12556&& $asc <=-11848) return ' X ';  if ($asc >=-11847&& $asc <=-11056) return ' Y ';  if ($asc >=-11055&& $asc <=-10247) return ' Z '; return null;} $pinyin = Array (' name ' = ' Tony Leung ', ' age ' =>23), Array (' name ' + ' Andy ', ' age ' =>24), Array (' name ' = ' Dawn ') , ' age ' =>19), Array (' name ' = ' Aaron Kwok ', ' age ' =>20); $sort = Array (); foreach ($pinyin as $key = = $item) {$py = zhcnt  Opinyin ($item [' name ']); $pinyin [$key] [' Pinyin '] = $py; $sort [] = $py;} Array_multisort ($sort, SORT_ASC, $pinyin); Var_dump ($pinyin);? >

The results of the operation are as follows:

Array (4) {[0]=> Array (3) {  ["name"]=>  string (4) "Andy"  ["Age"]=>  Int ()  ["Pinyin"]= >  string (1) "A"} [1]=> Array (3) {  ["name"]=>  string (6) "Aaron Kwok"  ["Age"]=>  Int (20)  ["Pinyin"]=>  string (1) "G"} [2]=> Array (3) {  ["name"]=>  string (4) "Dawn"  ["Age"]= >  int  ["Pinyin"]=>  string (1) "L"} [3]=> Array (3) {  ["name"]=>  string (6) " Tony Leung "  [" Age "]=>  int  [" Pinyin "]=>  string (1)" L "}}

The above is the whole content of this article, I hope that everyone's study has helped.
