php将新字段添加到数组并将其显示

Question

下面给出的代码是读取csv文件并将值检索到字段$ time，$ sip，$ dip和$ data。我需要检索，

1. first_time_stamp
2. SIP/DIP
3. sum_of_all_values_at_SIP
4. sum_of_all_values_at_DIP

下面的代码是总和起来。但我找不到分开的啜饮。我需要分开寻找啜饮和浸泡。也是第一次的时间戳。

2014-10-31 23:34:06,10.101.11.122,54.252.136.82,2047 
2014-10-31 23:34:08,31.13.70.81,10.101.84.6,49580 
2014-10-31 23:34:15,10.101.11.122,54.252.136.82,20 
2014-10-31 23:34:09,54.252.136.82,10.101.11.122,20 
2014-10-31 23:34:12,10.101.11.13,10.101.11.122,20 

如：

$lines =file('/ghgj.csv'); 
    $records=array(); 
    $i=1; 
    foreach($lines as $line) 
    { 

    list($time,$sip,$dip,$data)= explode(',',$line); 
    if(substr($sip, 0, 3)=="10.") 
    { 
      if(key_exists($sip, $records)) 
      { 
       $records[$sip] += $data; 
      } 
      else 
      { 
       $records[$sip] = $data; 
      } 

    } 
    else if(substr($dip, 0, 3)=="10.") 
    {   
      if(key_exists($dip, $records)) 
      { 
      $records[$dip] += $data; 
      } 
      else 
      { 
       $records[$dip] = $data; 
      } 
    } 
    else 
    { 
     continue; 
    } 
    $i++; 
    } 
    } 

CSV文件的例子在下面给出我的代码输出：

10.101.11.122(sip or dip),2087 
10.101.84.6,49580 
10.101.11.13,20 

如：输出应该是这样的：

2014-10-31 23:34:06(timestamp),10.101.11.122(common sip or dip),2067(sum of sip),20(sum of dip) 
2014-10-31 23:34:08,10.101.84.6,0,49580 
2014-10-31 23:34:06,10.101.11.13,20,0 

谢谢！

看看这是否适合你。正如@jerdiggity所写的，你也可以使用fgetcsv（），但在你的情况下（没有引号，特别是CSV数据中没有引用逗号或换行符），这是没有必要的。

$lines =file('/ghgj.csv'); 
$records=array(); 
$i=1; 
foreach($lines as $line) 
{ 
    list($time,$sip,$dip,$data)= explode(',',$line); 
    if(substr($sip, 0, 3)=="10.") 
    { 
     if (!key_exists($sip, $records)) 
     { 
      $records[$sip] = array(
       'timestamp' => $time, 
       'sip'  =>  0, 
       'dip'  =>  0 
      ); 
     } 
     $records[$sip]['sip'] += $data; 
    } 
    else if(substr($dip, 0, 3)=="10.") 
    {   
     if (!key_exists($dip, $records)) 
     { 
      $records[$dip] = array(
       'timestamp' => $time, 
       'sip'  =>  0, 
       'dip'  =>  0 
      ); 
     } 
     $records[$dip]['dip'] += $data; 
    } 
    else 
    { 
     continue; 
    } 
    $i++; 
}
