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));
?>
