本文实例讲述了php实现数组按拼音顺序排序的方法。分享给大家供大家参考,具体如下:
一、问题:
给定数组要求实现按照其汉字首字母排序:
1
2
3
4
5
6
|
$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) ); |
二、解决方法:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22

<?php /* * Created on 2017-5-3 * author: www.zzvips.com * */ function zhcnToPinyin( $str ) //汉字转拼音函数 { if ( empty ( $str )){ return '' ;} $fchar =ord( $str {0}); if ( $fchar >=ord( 'A' )&& $fchar <=ord( 'z' )) return strtoupper ( $str {0}); $s1 =iconv( 'UTF-8' , 'gb2312' , $str ); $s2 =iconv( 'gb2312' , 'UTF-8' , $s1 ); $s = $s2 == $str ? $s1 : $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 ( 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) ); $sort = array (); foreach ( $pinyin as $key => $item ) { $py = zhcnToPinyin( $item [ 'name' ]); $pinyin [ $key ][ 'pinyin' ] = $py ; $sort [] = $py ; } array_multisort ( $sort , SORT_ASC, $pinyin ); var_dump( $pinyin ); ?> |
运行结果如下:
1
2
3
4
5
6
7
8
9
10
11

array (4) { [0]=> array (3) { [ "name" ]=> string(4) "andy" [ "age" ]=> int(24) [ "pinyin" ]=> string(1) "A" } [1]=> array (3) { [ "name" ]=> string(6) "郭富城" [ "age" ]=> int(20) [ "pinyin" ]=> string(1) "G" } [2]=> array (3) { [ "name" ]=> string(4) "黎明" [ "age" ]=> int(19) [ "pinyin" ]=> string(1) "L" } [3]=> array (3) { [ "name" ]=> string(6) "梁朝伟" [ "age" ]=> int(23) [ "pinyin" ]=> string(1) "L" } } |
