格式顯示問題

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

主要是加了
最後一行顯示空格。如何修改可以把最後一行多的空格去除。謝謝！

回複討論(解決方案)

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

4409 * 300
4410 * 75

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

4409 * 300
4410 * 75

如果變成這樣呢？
foreach($ress as $source)
{
if($source['cust_no'] == '237033AW0A')
{
if($source['part_count'] != 0)
{
$lotno_count[] = $source['lotno'].' * '.$source['part_count'];
}
}
}

那有什麼區別呢？
你不過只是在直接輸出時多了最後的

只要能判斷出是最後一個就不需要緩衝了
