这篇文章主要介绍了在php中用for循环对数组进行冒泡排序并打印，有一定的参考价值，感兴趣的朋友可以看看，希望可以帮助到你！

<!DOCTYPE html>
<html>
<body>
<h1>原来是PHP啊！</h1>
<?php
//冒泡排序并打印排序后的数组
$a=array(2,1,4,3,5,6);
$length=count($a);
for($i=0;$i<$length;$i++){
for($j=0;$j<$length-1-$i;$j++){
if($a[$j+1]<$a[$j]){
$b=$a[$j];
$a[$j]=$a[$j+1];
$a[$j+1]=$b;
}
}
echo $a[$i]," ";
}
?>  
</body>
</html>

结果为1 2 3 4 5 6

当然，也可以直接使用函数sort()或者rsort()直接进行排序。
