PHP array dynamically adds implementation code (price sorting of the Tutu group buying system), array group buying

Recently implementing the price sorting function of the Tutu group buying system, the $oc array needs to be To expand, use the following method after testing.

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.
