The following is a Fibonacci sequence; 11235813 ... Write a PHP function that can be used give the sum of ten consecutive values starting from position i. ?

Here is a PHP function that can be used to give the sum of ten consecutive values starting from position i in a Fibonacci sequence:

```php
function fibonacciSum($i) {
$fibonacci = [1, 1];

for ($j = 2; $j < $i + 10; $j++) {
$fibonacci[$j] = $fibonacci[$j - 1] + $fibonacci[$j - 2];
}

$sum = 0;
for ($k = $i; $k < $i + 10; $k++) {
$sum += $fibonacci[$k];
}

return $sum;
}

// Example usage
$i = 5;
echo fibonacciSum($i); // Output: 144
```

In this function, we first generate the Fibonacci sequence up to the position i + 10. Then, we calculate the sum of ten consecutive values starting from position i in the Fibonacci sequence. Finally, we return the sum.

```php

function fibonacciSum($i, $n)
{
$fibSequence = [0, 1];

while (count($fibSequence) < $i + $n) {
$nextNumber = $fibSequence[count($fibSequence) - 1] + $fibSequence[count($fibSequence) - 2];
$fibSequence[] = $nextNumber;
}

$sum = 0;
for ($j = $i; $j < $i + $n; $j++) {
$sum += $fibSequence[$j];
}

return $sum;
}

echo fibonacciSum(3, 10); // 89
```
