如何转换下面的数组

Array
(
    [0] => stdClass Object
        (
            [name] => color
            [value] => red
        )

    [1] => stdClass Object
        (
            [name] => color
            [value] => black
        )

    [2] => stdClass Object
        (
            [name] => color
            [value] => green
        )

    [3] => stdClass Object
        (
            [name] => volume
            [value] => 15L
        )

    [4] => stdClass Object
        (
            [name] => volume
            [value] => 25L
        )

)

对于这样的人

Array(
    'colors'  => red, black, green
    'volumes' => 15L, 25L
)

此代码

foreach( $result as $r )
    {           
        if( $mem !== $r->name ) unset($attribs[$r->name . "s"]);            
        $string .= $r->value . ", ";                    
        $attribs[$r->name . "s"] = reduce_multiples($string, ", ", TRUE); //removes the last comma from the string          
        $mem = $r->name;                    
    }

打印

Array
(
    [colors] => red, black, green
    [volumes] => red, black, green, 15L, 25L
)

$ result是上面的第一个数组代码段。它很接近但不完全存在。这条线

if( $mem !== $r->name ) unset($attribs[$r->name . "s"]);

目前什么都不做，但我认为这些都是我需要省略卷中的“红色，黑色，绿色”。

Answer 1

创建一个迭代数组的函数，生成所需的数组类型。没有内置方法。

Answer 2

$newArray = array();
foreach($oldArray as $obj) {
   $name = $obj->name.'s';
   $value = $obj->value;
   if array_key_exists($name,$newArray) {
      $newArray[$name] .= ', '.$value;
   } else {
      $newArray[$name] = $value;
   }
}
var_dump($newArray);
