I have an array that looks like this:
Array ( [0] => 1 [1] => 1 [2] => 3 )
I'd like to get the sum of the values excluding the last value.
So in this example I'm looking to find the answer to 1 + 1.
The array could be varying lengths.

Answer 1

You can do like this
$myArray= [1,1,3];
array_pop($myArray); // Remove the last element from array
echo array_sum($myArray); // Sum the values of the array

Answer 2

You can do something like this
<?php $array = array(1, 1, 3);
$sliced = array_slice($array, 0, -1); ?>
This will return you 1 & 1 it won't give you 3

Answer 3

<?php $value = array(1,1,3);
$removed = array_pop($value);
echo array_sum($value);
?>

Answer 4

Another way to do using closure
$array = [1,1,3];
echo array_sum(array_filter($array, function($key) use ($array) {
return count($array) - 1 !== $key;
}, ARRAY_FILTER_USE_KEY));

Answer 5

try this its very simple & fastest way
// initialize array by 'short syntax'
$a = [
1,1,3
];
//remove last element of array no matter length
// This function will reset() the array pointer of the input array after use.
array_pop($a);
// then you can sum of rest array values by array_sum
echo array_sum($a);
