如何从多维数组中删除不必要的行？

我有一个指纹记录这样如何从多维数组中删除不必要的行？

"OUR COMPANY";"100";"100";07/25/2017 5:02:57 PM;"Check Out";"1";"";0;"Fingerpint";"" 
"OUR COMPANY";"102";"102";07/25/2017 7:45:53 AM;"Check In";"1";"";0;"Fingerpint";""

格式化：

Array 
(
    [0] => Array 
     (
      [0] => "OUR COMPANY" 
      [1] => "100" 
      [2] => "100" 
      [3] => 07/25/2017 5:02:57 PM 
      [4] => "Check Out" 
      [5] => "1" 
      [6] => "" 
      [7] => 0 
      [8] => "Fingerpint" 
      [9] => "" 
     ) 

    [1] => Array 
     (
      [0] => "OUR COMPANY" 
      [1] => "102" 
      [2] => "102" 
      [3] => 07/25/2017 7:45:53 AM 
      [4] => "Check In" 
      [5] => "1" 
      [6] => "" 
      [7] => 0 
      [8] => "Fingerpint" 
      [9] => "" 
     ) 

    [2] => Array 
     (
      [0] => "OUR COMPANY" 
      [1] => "102" 
      [2] => "102" 
      [3] => 07/25/2017 7:45:54 AM 
      [4] => "Check In" 
      [5] => "1" 
      [6] => "" 
      [7] => 0 
      [8] => "Fingerpint" 
      [9] => "" 
     ) 
    ... 
)

，我只希望获得每个入住和退房第一条记录。该记录包含多个条目，如ID为102的每个ID有2个Check Ins和2 Check Out。我只想获取第一个记录的Check In和第一个记录Check Out。这是我的方法。

while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) { 
     $num = count($data); 
     for ($c=0; $c < $num; $c++) { 
      if ($c == 1 || $c == 2 || $c == 3 || $c == 4) { 
       if($d != 0){ 
        $dtary[$d][$c] = $data[$c] ; 
       } 
      } 
      if ($c == 9) { 
       $d++ ; 
      } 
     } 
    }

如何设置条件？

请格式化你的阵列 – JYoThI

同时发布你的尝试，让我们看看你已经尝试过。 – Rasclatt

我认为它应该是* Check in的第一个记录和Check Out的＃last＃记录。*不是吗？ – JYoThI

这是您预期的结果？

"OUR COMPANY";"100";"100";07/25/2017 5:02:57 PM;"Check Out";"1";"";0;"Fingerpint";"" 
"OUR COMPANY";"102";"102";07/25/2017 7:45:53 AM;"Check In";"1";"";0;"Fingerpint";"" 
"OUR COMPANY";"102";"102";07/25/2017 6:01:34 PM;"Check Out";"1";"";0;"Fingerpint";""

您应该尝试array_intersect。

如果约束只是ID and 'Check In/Out'不考虑Datetime或每天独特Check In/Out，然后检查了这一点：

<?php 

$myArray = array(); 
$myArray[] = array("OUR COMPANY","100","100","07/25/2017 5:02:57 PM","Check Out","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","102","102","07/25/2017 7:45:53 AM","Check In","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","102","102","07/25/2017 7:45:54 AM","Check In","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","102","102","07/25/2017 6:01:34 PM","Check Out","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","102","102","07/25/2017 6:01:35 PM","Check Out","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","104","104","07/25/2017 8:00:06 AM","Check Out","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","104","104","07/25/2017 5:35:19 PM","Check In","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","105","105","07/25/2017 8:47:37 AM","Check In","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","108","108","07/25/2017 8:45:42 AM","Check In","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","108","108","07/25/2017 6:04:00 PM","Check Out","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","11","11","07/25/2017 8:57:34 AM","Check In","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","11","11","07/25/2017 5:12:06 PM","Check Out","1","",0,"Fingerpint",""); 
$myArray[] = array("OUR COMPANY","112","112","07/25/2017 8:43:56 AM","Check In","1","",0,"Password",""); 
$myArray[] = array("OUR COMPANY","112","112","07/25/2017 5:39:26 PM","Check Out","1","",0,"Password",""); 
$myArray[] = array("OUR COMPANY","112","112","07/25/2017 5:41:17 PM","Check Out","1","",0,"Password",""); 


/** 
* Compare two arrays and return true if intersected counts are the same. 
*/ 
function in_array_intersect ($target, $haystack) { 
    foreach ($haystack as $item) { 
     if ((count(array_intersect(array($item[1], $item[4]), $target)) == count($target))) { 
      return true; 
     } 
    } 
    return false; 
} 

// Define a new array to hold the matched records 
$resultArray = array(); 

foreach ($myArray as $subArray) { 
    // Create a new array with only two columns, ID and CheckIn/Out 
    $target = array($subArray[1], $subArray[4]);  
    if (!in_array_intersect($target, $resultArray)){ 
     // Add $subArray to $resultArray if no array is found in $resultArray by matching the columns constraint 
     array_push($resultArray, $subArray); 
    } 
} 

echo '<pre>'; 
print_r($resultArray); 
echo '</pre>'; 

?>

结果：

感谢兄弟这工作正常。你能否向我解释一些代码，以便将来可以更改或修改。无论如何，谢谢。 –

答案已经更新并添加了一些评论。 – kolunar

您需要loop阵列和build新array像下面

1：在环店check In每个unique id的第一项则忽略该ID的所有其他check In条目。

第二：在环店check Out的last entry每个unique id所以你刚才overwrite各条目。 if($val['4']=="Check Out"){.. } .

PHP：

<?php 


$data = Array(

     "0" => Array 
      (
       "0" => "OUR COMPANY", 
       "1" => "100", 
       "2" => "100", 
       "3" => "07/25/2017 5:02:57 PM", 
       "4" => "Check Out", 
       "5" => "1", 
       "6" => "", 
       "7" => 0, 
       "8" => "Fingerpint", 
       "9" => "" 
      ), 

     "1" => Array 
      (
       "0" => "OUR COMPANY", 
       "1" => "102", 
       "2" => "102", 
       "3" => "07/25/2017 7:45:53 AM", 
       "4" => "Check In", 
       "5" => "1", 
       "6" => "", 
       "7" => 0, 
       "8" => "Fingerpint", 
       "9" => "" 
      ), 

     "2" => Array 
      (
       "0" => "OUR COMPANY", 
       "1" => "102", 
       "2" => "102", 
       "3" => "07/25/2017 7:45:54 AM", 
       "4" => "Check In", 
       "5" => "1", 
       "6" => "", 
       "7" => 0, 
       "8" => "Fingerpint", 
       "9" => "" 
      ), 
    "3" => Array 
      (
       "0" => "OUR COMPANY", 
       "1" => "100", 
       "2" => "100", 
       "3" => "07/25/2017 6:02:57 PM", 
       "4" => "Check In", 
       "5" => "1", 
       "6" => "", 
       "7" => 0, 
       "8" => "Fingerpint", 
       "9" => "" 
      ), 
    "4" => Array 
      (
       "0" => "OUR COMPANY", 
       "1" => "102", 
       "2" => "102", 
       "3" => "07/25/2017 8:45:54 AM", 
       "4" => "Check Out", 
       "5" => "1", 
       "6" => "", 
       "7" => 0, 
       "8" => "Fingerpint", 
       "9" => "" 
      ), 

    ); 

$final_array=array(); 
foreach($data as $key=>$val) 
{ 

    if(!isset($final_array[$val['1']]['check_in']) && $val['4']=="Check In"){ 


     $final_array[$val['1']]['check_in']=$val[3]; 
    } 

    if($val['4']=="Check Out"){ 
    $final_array[$val['1']]['check_out']=$val[3]; 

    } 

} 

echo "<pre>"; 
print_r($final_array); 
?>

OUTPUT：

Array 
(
    [100] => Array 
     (
      [check_out] => 07/25/2017 5:02:57 PM 
      [check_in] => 07/25/2017 6:02:57 PM 
     ) 

    [102] => Array 
     (
      [check_in] => 07/25/2017 7:45:53 AM 
      [check_out] => 07/25/2017 8:45:54 AM
