php - 连接数组值，如果包含重复项 - php

Question

这是我的数组。如果存在重复项，我需要连接数组值。

Array
(
    [0] => Array
        (

            [id] => 3
            [location_id] => 2            
            [location_name] => 1st Floor 
            [type] => 1           
        )

    [1] => Array
        (

            [id] => 6
            [location_id] => 2           
            [location_name] => 1st Floor 
            [type] => 1           
        )

    [2] => Array
        (           
            [id] => 7
            [location_id] => 1            
            [location_name] => Ground Floor 
            [type] => 1        
        )

)

下面是我的代码，它不连接唯一值。

$conct= array();
foreach ($myArray as $array)
{
    foreach ($array as $key => $value)
    {               
        if ( ! isset($merged[$key]))
        {
            $conct[$key] = $value;
        }
        else
        {
            $conct[$key] .= ",".$value;
        }
    }
}

这是给我的。

Array
(
    [0] => Array
        (

            [id] => 3,6,7
            [location_id] => 2,2,1            
            [location_name] => 1st Floor,1st Floor,Ground Floor
            [type] => 1,1,1       
        )


)

我需要根据 unique location_id 和 location_name 连接值。我的结果数组应该是。

Array
(
    [0] => Array
        (

            [id] => 3,6
            [location_id] => 2,2            
            [location_name] => 1st Floor,1st Floor 
            [type] => 1,1           
        )

    [1] => Array
        (

            [id] => 7
            [location_id] => 1           
            [location_name] => Ground Floor 
            [type] => 1           
        )


)

如何实现？

Answer 1

试试这个..

<?php

$new_values = array();
$values = array(
    array('id'=> 1, 'location_id' => 2, 'location_name' => '1st Floor','type'=>1),
    array('id'=> 6, 'location_id' => 2, 'location_name' => '1st Floor','type'=>1),
   array('id'=> 7, 'location_id' => 1, 'location_name' => 'Gound Floor','type'=>1),
);

foreach($values as $value) {
    if(isset($new_values[$value['location_id']])) {
        $temp = $new_values[$value['location_id']];
        $temp['id'] .= ',' . $value['id'];
        $temp['location_id'] .= ',' . $value['location_id'];
         $temp['location_name'] .= ',' . $value['location_name'];
          $temp['type'] .= ',' . $value['type'];
        $new_values[$value['location_id']] = $temp;
    } else {
        $new_values[$value['location_id']] = $value;
    }
}

$new_values = array_values($new_values);
print_r($new_values);
?>

输出:Array ( [0] => Array ( [id] => 1,6 [location_id] => 2,2 [location_name] => 1st Floor,1st Floor [type] => 1, 1 ) [1] => 数组 ( [id] => 7 [location_id] => 1 [location_name] => 地下层 [type] => 1 ) )
