PHP's 10 integers, sort from small to large, and output the sorting results

<code><span>$aray</span> = <span>array</span>(<span>5</span>,<span>4</span>,<span>3</span>,<span>2</span>,<span>6</span>,<span>7</span>,<span>9</span>,<span>8</span>,<span>1</span>,<span>10</span>);
 <span>for</span>(<span>$i</span>=<span>0</span>;<span>$i</span><count(<span>$aray</span>);<span>$i</span>++){
      <span>for</span>(<span>$j</span>=<span>$i</span>+<span>1</span>;<span>$j</span><count(<span>$aray</span>);<span>$j</span>++){
          <span>$a</span>=<span>$aray</span>[<span>$i</span>];
          <span>$b</span>=<span>$aray</span>[<span>$j</span>];
          <span>if</span>(<span>$a</span>><span>$b</span>){
            <span>$aray</span>[<span>$i</span>]=<span>$b</span>;
            <span>$aray</span>[<span>$j</span>]=<span>$a</span>;
          }

      }
 }
 <span>//输出排序好的</span><span>for</span>(<span>$k</span>=<span>0</span>;<span>$k</span><count(<span>$aray</span>);<span>$k</span>++){
    <span>echo</span><span>$aray</span>[<span>$k</span>].<span>','</span>;

  }
