最近在实现最土团购系统的价格排序功能,需要对$oc数组进行扩展，经过测试用下面的方法即可。
核心代码如下:
<?<span>php
</span><span>$now</span>=<span>time</span><span>();
</span><span>$oc</span> = <span>array</span><span>(
</span>'team_type' => 'normal',
"begin_time < '{<span>$now</span>}'",
"end_time > '{<span>$now</span>}'",<span>
);
</span><span>$p</span>="p2"<span>;
</span><span>$pp1</span>=""<span>;
</span><span>$pp2</span>=""<span>;
</span><span>$now</span> = <span>time</span><span>();
</span><span>switch</span> (<span>$p</span><span>)
{
</span><span>case</span> "p1":
<span>$pp1</span>="team_price < 10"<span>;
</span><span>$pp2</span>=""<span>;
</span><span>break</span><span>;
</span><span>case</span> "p2":
<span>$pp1</span>="team_price > 10"<span>;
</span><span>$pp2</span>="team_price < 50"<span>;
</span><span>break</span><span>;
</span><span>case</span> "p3":
<span>$pp1</span>="team_price > 50"<span>;
</span><span>$pp2</span>="team_price < 100"<span>;
</span><span>break</span><span>;
</span><span>case</span> "p4":
<span>$pp1</span>="team_price > 100"<span>;
</span><span>$pp2</span>="team_price < 200"<span>;
</span><span>break</span><span>;
</span><span>case</span> "p5":
<span>$pp1</span>="team_price > 200"<span>;
</span><span>$pp2</span>=""<span>;
</span><span>break</span><span>;
</span><span>default</span>:
<span>$pp1</span>=""<span>;
</span><span>$pp2</span>=""<span>;
}
</span><span>if</span>(!<span>empty</span>(<span>$pp1</span><span>)){
</span><span>array_push</span>(<span>$oc</span>,<span>$pp1</span><span>);
}
</span><span>if</span>(!<span>empty</span>(<span>$pp2</span><span>)){
</span><span>array_push</span>(<span>$oc</span>,<span>$pp2</span><span>);
}
</span><span>print_r</span>(<span>$oc</span><span>);
</span><span>/*</span><span> 何问起 hovertree.com </span><span>*/</span>
?>因为是多条件查询所以需要先判断是否为空，然后再添加到数组里面。
