下面给出的代码是读取csv文件并将值检索到$ time,$ sip,$ dip和$ data字段。我需要检索,
下面的代码是总和。但我找不到分开的啜饮和蘸酱。我需要分别找到啜饮和蘸酱。也是第一个时间戳。
$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文件的示例如下:
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
例如:输出我的代码:
10.101.11.122(sip or dip),2087
10.101.84.6,49580
10.101.11.13,20
例如:输出应如下所示:
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!

看看这是否适合您。正如@jerdiggity所写,你也可以使用fgetcsv(),但在你的情况下(没有引号,特别是你的CSV数据中没有引用的逗号或换行符),它不是必需的。
$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++;
}
