更改php中的数组结构

如何像在test2中一样更改test1数组格式

$test1 = array(
    'size'=>array('V'=>array('V'),'R'=>array('R','R')),
    'price'=>array('V'=>array('77'),'R'=>array('88','99')),
    'unit'=>array('V'=>array('3'),'R'=>array('3','2')),
    'color'=>array('V'=>array('Black'),'R'=>array('Green','Red')));

$test2 = array(
    'size'=>array('V','R'),
    'price'=>array('V'=>array('Black'=>'77'),
                   'R'=>array('Green'=>'88','Red'=>'99')),
    'unit'=>array('V'=>array('Black'=>'3'),
                  'R'=>array('Green'=>'3','Red'=>'2')),
    'color'=>array('V'=>array('Black'),'R'=>array('Green','Red')));

谢谢

使用foreach循环可以更改数组结构。 类似的方法应该会起作用：在您的情况下，从一个数组转换到另一个数组的规则非常不明确

$test2 = array();
foreach ($test as $type => $array) {
    $newArray = array();
    foreach ($array as $key => $value) {
        if ($key == 'V') {
            if ($value == 3) {
                $newArray['V'] = array('Black' => 3);
            } else if ($value = 2) {
                $newArray['V'] = array('Green' => 2);
            }
        } else if ($key == 'R') {
            //....
        }
    }
    $test2[$type] = $newArray;
}

谢谢你的回复。很抱歉没有说得更具体。实际上，我希望所有的值都是动态的。我构造了一个循环：。谢谢

$myArray = array();
foreach($test as $type => $array){
    $k = 0;
    foreach ($array as $key => $value) {
    if($type == 'size'){
        $myArray['size'][] = $key;
    }else if($type == 'price' || $type == 'unit' ){ 
        $m = 0;
        foreach($value as $vall){
            if($type == 'price'){
                $myArray['price'][$myArray['size'][$k]][$test['color'][$myArray['size'][$k]][$m]] = $test['price'][$myArray['size'][$k]][$m];
            }else if($type == 'unit'){
                $myArray['unit'][$myArray['size'][$k]][$test['color'][$myArray['size'][$k]][$m]] = $test['unit'][$myArray['size'][$k]][$m];
            }
            $m++;
        }
    }else if($type == 'color'){
        $myArray['color'][] = $value;
    }
    $k++;
}
}

原来你的问题不一样。您应该使用嵌套的foreach循环，以便可以检查每个变量。
