I want to multiply quantity value in multi dimensional array and also get the result based on the quantity
This is the array:
$meal_plan[$res['week']][$res2['day']][$res3['meal_plan_type']][$res3['quantity']][]=$res4;
This is the loop:
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'] ;
}
}
}
}
This is my array, I want to multiply the value of cabs/ protein/ fat etc with the quantity array. How to do that ?

From your code it seems you want separate totals per day. So then you would do it like this:
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
];
}
}
See it run on eval.in.
