I have an array. I am trying to print the values of the array like this

print_r(\$travellers_data['variation']);

so it is showing me data like this.

Array

(

[child_travelers] => 2

[infant_travelers] => 4

)

Array

(

[child_travelers] => 11

[infant_travelers] => 14

)

Here you can see there are two array blocks containing different age group of travellers.

Now I want to get sum of the total travellers for both the array block. so the result should be like this

total_travellers = adults_travelers + child_travelers + infant_travelers;

total_travellers = 13 + 13 + 18 = 44;

so someone tell me how to get the sum of two array blocks. Any help and suggestions will be really appreciable. Thanks

\$travelers = [
['adults_travelers' => 1, 'child_travelers' => 2, 'infant_travelers' => 4],
['adults_travelers' => 12, 'child_travelers' => 11, 'infant_travelers' => 14]
];

\$sum = array_reduce(\$travelers, function (\$sum, array \$array) {
return \$sum + array_sum(\$array);
});

since \$travellers_data['variation'] is an array of arrays, we need to loop over it and then sum the individual arrays and add them to our total count. php has a function array_sum which conveniently totals the elements of an array, and it is clever enough to just look at the values of an associative array. we can put it all together into a very simple solution like this:

\$sum = 0;
foreach(\$travellers_data['variation'] as \$arr)
{
\$sum += array_sum(\$arr);
}

this assumes that your arrays ONLY contain traveler information as shown in your question, and not some other values

Thanks for those answers. I just did it my self like this

\$total_persons = array();
foreach(\$travellers_datas as \$travellers_data) {
