如何对下面的数据进行排序

Black Tiger / HL / Regular G2 - 10x2000/2000 - 13/15 ()<br>
Black Tiger / HL / Regular G2 - 10x2000/2000 - 16/20 ()<br>
Black Tiger / HL / Regular G2 - 10x2000/2000 - 21/25 ()<br>
Black Tiger / HL / Regular G2 - 10x2000/2000 - 3/6 ()<br>
Black Tiger / HL / Regular G2 - 10x2000/2000 - 8/12 ()<br>
Black Tiger / HL / Regular G2 - 6x2000/2000 - 13/15 (0)<br>
Vannamei / HOSO / Regular - 10x800/1000 - 31/40 (50)<br>
Vannamei / HOSO / Regular - 10x800/1000 - 40/60 (75)<br>
Vannamei / HOSO / Regular - 10x800/1000 - 61/80 (100)<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 8/12 (15)<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 13/15 (18.75)<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 16/20 (25)<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 21/25 (31.25)<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 26/30 (37.5)<br>

应该像这样排序

Black Tiger / HL / Regular G2 - 10x2000/2000 - 3/6 ()<br>
Black Tiger / HL / Regular G2 - 10x2000/2000 - 8/12 ()<br>
Black Tiger / HL / Regular G2 - 10x2000/2000 - 13/15 ()<br>
Black Tiger / HL / Regular G2 - 10x2000/2000 - 16/20 ()<br>
Black Tiger / HL / Regular G2 - 10x2000/2000 - 21/25 ()<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 8/12 (15)<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 13/15 (18.75)<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 16/20 (25)<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 21/25 (31.25)<br>
Vannamei / HOSO / Horeca - 10x800/1000 - 26/30 (37.5)<br>
Vannamei / HOSO / Regular - 10x800/1000 - 31/40 (50)<br>
Vannamei / HOSO / Regular - 10x800/1000 - 40/60 (75)<br>
Vannamei / HOSO / Regular - 10x800/1000 - 61/80 (100)

【问题讨论】：

所有这些数据是否都存储在一列中？
不是一个有效的问题。你只是要求我们做你的工作。你试过什么？排序的条件是什么？
使用php.net/manual/en/function.usort.php

【解决方案1】：

你可以通过下面的查询得到结果，但是如果数据量很大，查询会很慢。

SELECT * FROM mytable ORDER BY LEFT(myfield,5), SUBSTRING_INDEX(SUBSTRING_INDEX(myfield,'-',-1),'/',1);
