我正在尝试过滤这两个数组。
第一个数组（$posters）有大约600条记录：$ poster = array
Array
(
[0] => Array
(
[Poster_ID] => 8
[Brand] => xyz
[Therapy] => xyz
[Agency] => xyz
[Client_Approval] => 1
[Poster_Number] => ...
[Identifier] => 517035
[Presentation_Date] => 2011-11-15 00:00:00
[Expiry_Date] => 2012-11-14 00:00:00
)
[1] => Array
(
[Poster_ID] => 8
[Brand] => xyz
[Therapy] => xyz
[Agency] => xyz
[Client_Approval] => 1
[Poster_Number] => ...
[Identifier] => 517035
[Presentation_Date] => 2011-11-15 00:00:00
[Expiry_Date] => 2012-11-14 00:00:00
)
[2] => Array
(
[Poster_ID] => 5
[Brand] => Lialda
[Therapy] =>
[Agency] => MedErgy Scientific
[Client_Approval] => 1
[Poster_Number] => P173
[Identifier] => 444909
[Presentation_Date] => 2012-02-17 00:00:00
[Expiry_Date] => 2012-03-18 01:00:00
) up to 600. These data come from database
另一个数组（$stats_result）至少有来自Google Analytics（分析）帐户的9000条记录，如下所示：
[0] => Array
(
[0] => 20120126
[1] => /249441
[2] => 1
[3] => 2
[4] => 1
)
[1] => Array
(
[0] => 20120126
[1] => /249441/pdf-emailed.php
[2] => 1
[3] => 1
[4] => 1
)
[2] => Array
(
[0] => 20120127
[1] => /517035
[2] => 1
[3] => 2
[4] => 1
)
[3] => Array
(
[0] => 20120129
[1] => /517035
[2] => 1
[3] => 1
[4] => 1
)
[4] => Array
(
[0] => 20130503
[1] => /257388/email_sent/PT
[2] => 1
[3] => 6
[4] => 1
)
[5] => Array
(
[0] => 20130606
[1] => /417202/email_sent/UK
[2] => 1
[3] => 1
[4] => 1
)
[6] => Array
(
[0] => 20130410
[1] => http://www.xyz.com/uploads/France/819412/download/FR.pdf
[2] => 1
[3] => 9
[4] => 1
)
[7] => Array
(
[0] => 20130411
[1] => http://www.xyz.com/uploads/149096.pdf
[2] => 1
[3] => 5
[4] => 1
)
.....
从Google解析中检索此数据后，我将循环结果并将其存储到单独的数组中：
for ($i=0; $i < count($stats_result); $i++) {
$stats_results[]=array(
'path' => $stats_result[$i][1],
'start_date' => $stats_result[$i][0],
'visitors'=>$stats_result[$i][2],
'emails'=>$stats_result[$i][4],
'downloads'=>$stats_result[$i][4]
);
}
然后我使用这个lambda函数来过滤这两个大数组，如下所示。此函数检查海报数组中的$poster['Idetifier']是否存在于第二个数组中（如果存在），然后检查日期。
foreach ($posters as &$poster)
{
$stats[] = array_filter($stats_results, function($item) use ($poster){
$date = strtotime($item['start_date']);
$presentation_date = strtotime($poster['Presentation_Date']);
$expiry=strtotime($poster['Expiry_Date']);
if($item['path'] == '/' . $poster['Identifier']){
return
($date >= $presentation_date && $date <= $expiry );
}
if($item['path'] == '/' . $poster['Identifier'].'/pdf-emailed.php'){
return
($date >= $presentation_date && $date <= $expiry);
}
if($item['path'] == 'http://www.xyz.com/uploads/' . $poster['Identifier'].'.pdf'){
return
($date >= $presentation_date && $date <= $expiry);
}
if($item['path'] == '/'.$poster['Identifier'].'/email_sent/DE'){
return
($date >= $presentation_date && $date <= $expiry);
}
if($item['path'] == '/'.$poster['Identifier'].'/email_sent/FR'){
return
($date >= $presentation_date && $date <= $expiry);
}
if($item['path'] == '/'.$poster['Identifier'].'/email_sent/ES'){
return
($date >= $presentation_date && $date <= $expiry);
}
if($item['path'] == '/'.$poster['Identifier'].'/email_sent/PT'){
return
($date >= $presentation_date && $date <= $expiry);
}
if($item['path'] == '/'.$poster['Identifier'].'/email_sent/IT'){
return
($date >= $presentation_date && $date <= $expiry);
}
if($item['path'] == '/'.$poster['Identifier'].'/email_sent/UK'){
return
($date >= $presentation_date && $date<= $expiry);
}
if($item['path'] == 'http://www.xyz.com/uploads/Germany/'.$poster['Identifier'].'/download/DE.pdf'){
return
($date >= $presentation_date && $date<= $expiry);
}
if($item['path'] == 'http://www.xyz.com/uploads/France/'.$poster['Identifier'].'/download/FR.pdf'){
return
($date >= $presentation_date && $date <= $expiry);
}
}
最后我根据下面的路径添加它们;
$finalStats = array();
foreach ($stats as $key => $value) {
foreach ($value as $stat){
if(isset($finalStats[$stat['path']])){
$finalStats[$stat['path']]['visitors'] += intval($stat['visitors']);
$finalStats[$stat['path']]['emails'] += intval($stat['emails']);
$finalStats[$stat['path']]['downloads'] += intval($stat['downloads']);
}else{
$finalStats[$stat['path']]['visitors'] = intval($stat['visitors']);
$finalStats[$stat['path']]['emails'] = intval($stat['emails']);
$finalStats[$stat['path']]['downloads'] = intval($stat['downloads']);
}
}
}
这一切都按预期工作。但无论如何我可以让这些过程更快。我首先尝试了isset（）函数，但执行需要很多时间。现在我已经尝试过lambda函数，但它仍然需要花费更多的时间来执行。有没有其他方法可以过滤这些数据。非常感谢你提前。需要认真帮助。
