格式显示问题

$ress = array ( 0 => array ( 0 => '237033AW0A', 'cust_no' => '237033AW0A', 1 => '4409', 'lotno' => '4409', 2 => 300, 'part_count' => 300, ), 1 => array ( 0 => '237033AW0A', 'cust_no' => '237033AW0A', 1 => '4410', 'lotno' => '4410', 2 => 141, 'part_count' => 75, ), )

foreach($ress as $source)
			{	
					if($source['part_count'] != 0)
					{
						$lotno_count = $source['lotno'].' * '.$source['part_count'];
						echo $lotno_count.'<br />';
					}
			}

主要是加了<br />最后一行显示空格。如何修改可以把最后一行多的空格去除。谢谢！

foreach($ress as $source) {   
  if($source['part_count'] != 0)
  {
    $lotno_count[] = $source['lotno'].' * '.$source['part_count'];
  }
}
echo join('<br />', $lotno_count);

4409 * 300<br />4410 * 75

引用 1 楼 xuzuning 的回复:

$ress = array ( 0 => array ( 0 => '237033AW0A', 'cust_no' => '237033AW0A', 1 => '4409', 'lotno' => '4409', 2 => 300, 'part_count' => 300, ), 1 => array ( 0 => '237033AW0A', 'cust_no' => '237033AW0A', 1 => '4410', 'lotno' => '4410', 2 => 141, 'part_count' => 75, ), );
 
foreach($ress as $source) {   
  if($source['part_count'] != 0)
  {
    $lotno_count[] = $source['lotno'].' * '.$source['part_count'];
  }
}
echo join('<br />', $lotno_count);

4409 * 300<br />4410 * 75

如果变成这样呢？ foreach($ress as $source) { if($source['cust_no'] == '237033AW0A') { if($source['part_count'] != 0) { $lotno_count[] = $source['lotno'].' * '.$source['part_count']; } } }

那有什么区别呢？ 你不过只是在直接输出时多了最后的 <br /> 只要能判断出是最后一个就不需要缓存了
