Solution in PHP (judge verdict: WA: Presentation Error)

<?php
$input = trim(fgets(STDIN));
$a = explode(' ',$input);

$x = $a[0];
$y = $a[1];
$z = $a[2];
	
for ($i = 0; $i < 3 ;$i++){
	if ($x > $y ){
		$temp = $x;
		$x = $y;
		$y = $temp;
	}
	if ($y > $z ){
		$temp = $y ;
		$y = $z;
		$z = $temp;	
	}
	
}
echo $x." ".$y." ".$z;
 exit;
