本文实例讲述了PHP简单实现冒泡排序的方法。分享给大家供大家参考，具体如下：

$files=array("file11.txt","file22.txt","file1.txt","file2.txt");
functionmySort($arr,$nat=false) {
    for($i=0;$i
      for($j=0;$j
        if($nat) {
          //按照strnatcmp()自然排序函数
          if(strnatcmp($arr[$j],$arr[$j+1])>0) {
            $tmp=$arr[$j];
            $arr[$j] =$arr[$j+1];//从小到大排
            $arr[$j+1] =$tmp;
          }
        }else{
          //按照strcmp()自然排序函数
          if(strcmp($arr[$j],$arr[$j+1])>0) {
            $tmp=$arr[$j];
            $arr[$j] =$arr[$j+1];//从小到大排
            $arr[$j+1] =$tmp;
          }
        }
      }
    }
    return$arr;
}
//Array ( [0] => file1.txt [1] => file11.txt [2] => file2.txt [3] => file22.txt )
print_r(mySort($files,false));
echo"
";
//2<11
//Array ( [0] => file1.txt [1] => file2.txt [2] => file11.txt [3] => file22.txt )
print_r(mySort($files,true));
?>
