关于php排序用法的详解

<div>
<blockquote><div>
<?php教程 <br />$array = array(10,5,36,86,2,56,9,15,8,4,3,41);<br>$num = count($array);<br>for($i = 0;$ifor($j = $i+1;$jif($array[$j]>$array[$i]){//这里交换数组的值<br>$temp = $array[$i];<br>$array[$i] = $array[$j];<br>$array[$j] =$temp;<br>}<br>}<br>}<br>print_r($array);<br>?></div></blockquote>　　这是写的冒泡排序算法，结果还是可以的：</div>

<div>---------- PHP Debug ----------<br><blockquote>Array<br>(<br>[0] => 86<br>[1] => 56<br>[2] => 41<br>[3] => 36<br>[4] => 15<br>[5] => 10<br>[6] => 9<br>[7] => 8<br>[8] => 5<br>[9] => 4<br>[10] => 3<br>[11] => 2<br>)<br>
