Copy code The code is as follows:
$arr = array(345,4,17,6,52 ,16,58,69,32,8,234);
$n = count($arr);
for($i=1;$i<$n;$i++){
//where Why $n-1 is because the array is calculated from 0
//The next is the first inner loop
for($j=$n-1;$j>=$i;$j --)
{
//If $arr[10]<$arr[9];
//temp = $arr[9];
if($arr[$j] <$arr[$j-1]){
//$temp put the small values together for now
$temp = $arr[$j-1];
//Start at this time The positions are about to be swapped
$arr[$j-1] = $arr[$j];
//$arr[9] = the value of $arr[10]
$arr[$j] = $temp;
//The value of $arry[10] is equal to the value of $arr[9]
//At this time, the positions will start to be exchanged
}
}
}
