用php做了下冒泡排序

大学没好好读书，那会没怎么明白冒泡排序是这么回事

早上睡到九点多起来，就在房间看书、听歌，下午吃完饭做了下冒泡排序，现在把代码贡献如下：

 

<?php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2016/8/27 0027
 * Time: 12:24
 * 冒泡排序
 */
header('Content-type: text/html; charset=utf-8');
$number=array("10","2","9","1","5","8","4","7","3","6");
for( $i=0;$i<count($number);$i++){
    echo $number[$i]. " ";
}
echo "<br/>";
echo  "冒泡后的顺序";
$temp=0;
for($n=0;$n<count($number);$n++){
    for($m=0;$m<count($number);$m++){
        if($number[$n]>$number[$m]){
            $temp=$number[$n];
            $number[$n]=$number[$m];
            $number[$m]=$temp;
        }
    }
}
for( $N=0;$N<count($number);$N++){
    echo $number[$N]. " ";
}
echo "<br/>";
die();
?>

其实还可以改良的，节省时间空间，有时间我拿来改改。
