Recently implementing the price sorting function of the Tutu group buying system, the $oc array needs to be expanded. After testing, the following method can be used.

The core code is as follows:

<?<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>?>

Because it is a multi-condition query, you need to first determine whether it is empty, and then add it to the array.

The above introduces the dynamic addition of PHP arrays to realize the price sorting of the code for the most local group buying system, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
