我想从我的pdf输出到raggrup数据像时间一样，当他们是相同的。
我正在使用tcpdf库
.
.
这就是我到目前为止所做的！
物料编号| bpm编号| sttpp编号|数量

A | 123 | 1231 | 100
A | 123 | 1232 | 200
B | 234 | 2341 | 100
B | 234 | 2342 | 100
C | 432 | 4321 | 100
D | 567 | 5671 | 100
D | 567 | 5672 | 600
D | 568 | 5681 | 300
D | 568 | 5682 | 200
D | 598 | 5981 | 100
D | 598 | 5672 | 90

下面的代码就是这样得到结果的！
这就是我想要的！
请帮我这是我的代码：

function realtime($durata){
  $tmp=$durata/3600;
  if (strpos($tmp,"." )>0) $ore	 = substr($tmp,0,strpos($tmp,"."));
  else $ore=$tmp;
  if ($ore<10) $ore='0'.$ore;
  $tmp=(($durata-($ore*3600))/60);
  if (strpos($tmp,"." )>0) $minuti	 = substr($tmp, 0,strpos($tmp,"." ));
  else $minuti=$tmp;
  if ($minuti<10) $minuti='0'.$minuti;
  $tmp=$durata-($ore*3600)-($minuti*60);
  if (strpos($tmp,"." )>0) $secondi = substr($tmp, 0,strpos($tmp,"." ));
  else $secondi=$tmp;
