我想在多维数组中乘以数量值，并根据数量获得结果
这是数组：
$meal_plan[$res['week']][$res2['day']][$res3['meal_plan_type']][$res3['quantity']][]=$res4;
这是循环：
foreach ($meal_plan as $week => $dayArr) {
foreach ($dayArr as $day => $meatTypeArr) {
$tFat = $tCal = $tKJoules = $tCarb = $tProt =0;
foreach ($meatTypeArr as $mealType => $meals) {
foreach ($meals as $mealQuantity => $mealq) { //quantity loop
foreach ($mealq as $meal_id => $meal) {
$tFat += $meal['total_fat'];
$tCal += $meal['calories'] ;
$tKJoules += $meal['kilojoules'] ;
$tCarb += $meal['carbs'] ;
$tProt += $meal['protien'] ;
}
}
}
}
这是我的数组，我想将 cabs/蛋白质/脂肪等的值与数量数组相乘。怎么做 ？
Array

[1] => Array

[3] => Array

[0] => Array

[calories] => 315
[kilojoules] => 1310
[carbs] => 18.6
[protien] => 18
)
)
)

[recepy_name] => Avocado - 60g

[kilojoules] => 522
[carbs] => 0.3

)
)
)
)
)
)
从您的代码看来，您每天需要单独的总数。那么你会这样做：
foreach ($meal_plan as $week => $dayArr) {
foreach ($dayArr as $day => $meatTypeArr) {
$tFat = $tCal = $tKJoules = $tCarb = $tProt = 0;
foreach ($meatTypeArr as $mealType => $meals) {
foreach ($meals as $mealQuantity => $mealq) { //quantity loop
foreach ($mealq as $meal_id => $meal) {
// Multiply each with $mealQuantity:
$tFat += $mealQuantity * $meal['total_fat'];
$tCal += $mealQuantity * $meal['calories'] ;
$tKJoules += $mealQuantity * $meal['kilojoules'] ;
$tCarb += $mealQuantity * $meal['carbs'] ;
$tProt += $mealQuantity * $meal['protien'] ;
}
}
}
// Add to result array (a set of totals per day)
$result[$week][$day] = [
"total_fat" => $tFat,
"calories" => $tCal,
"kilojoules" => $tKJoules,
"carbs" => $tCarb,
"protein" => $tProt
];
}
}
看看它在eval.in 上运行。
