Bubble sorting method in php

$arr=array(23,5,26,4,9,85,10,2,55,44,21,39,11,16,55,88,421,226,588);

$n = count($arr);/*count() function counts the number of cells in an array or the number of attributes in an object. For an array, return the number of its elements. For other values, return 1. If the argument is a variable and the variable is not defined, 0 is returned. If mode is set to COUNT_RECURSIVE (or 1), the number of elements in the array in the multidimensional array will be calculated recursively*/

//echo $n;

for($h=0;$h<$n -1;$h++){//Outer loop n-1

for($i=0;$i<$n-$h-1;$i++){

if($arr[$i]> ;$arr[$i+1]){//Judge the size of the array and reverse the position

$k/p> $arr[$i+1]=$arr[$i];

$arr[$i ]=$kong;

}

}

}

var_dump($arr);

?>Result: array(19) { [0]=> int(2) [ 1]=> int(4) [2]=> int(5) [3]=> int(9) [4]=> int(10) [5]=> int(11) [ 6]=> int(16) [7]=> int(21) [8]=> int(23) [9]=> int(26) [10]=> int(39) [ 11]=> int(44) [12]=> int(55) [13]=> int(55) [14]=> int(85) [15]=> int(88) [16]=> int(226) [17]=> int(421) [18]=> int(588) }
