Implementation of selection sort in PHP

This article mainly introduces to you the implementation of PHP selection sorting. The principle is: each traversal selects the smallest one on the right and exchanges its position with the one on the left. For example: in the first pass, select the first element 4 as a reference, find the right side of 4, and exchange the smallest number with 4 to become:0, 1,8,4,6,7,2,9,3,200,0,656,5,12,12123,34,9,

$arr[$j]){ $min= $j; } } if($min!=$i){ $t = $arr[$i]; $arr[$i] = $arr[$min]; $arr[$min] = $t; } foreach($arr as $v){ echo $v.","; } echo "
"; } ?>
