The **`array_sum`** method returns the sum of the array. 

# Syntax

```
array_sum(array $array): int|float
```

# Parameter

`array`: the array for which the sum is to be calculated. 

The return type of this method is either an int or a float value. If the array is empty, then zero is returned. 

# Code

<?php 

$arr = array(1,2,3);
echo "The array is \n"; 
print_r($arr);

echo "The sum is :"; 
echo array_sum($arr);

echo "\n-------\n";
$arr = array('a' => 1.4, 2);
echo "The array is \n"; 
print_r($arr);

echo "The sum is :"; 
echo array_sum($arr);

?>

In the code above: 
- We create an array with values `1,2,3` and call the `array_sum` method. This will return the sum of the array. In our case, it will return `6`. 
- We then create another array with values `1.4, 2`; for this array, `array_sum` will return `3.4` as a result.


In the array, the values that cannot be converted to numbers are skipped inside the `array_sum` method. For example: 

<?php 

$arr = array(1, "2", true, "yes", "no");
echo array_sum($arr);

?>

In the above code, we create an array with the values `1`, `"2"`, `true`, `"yes"`, and `"no"`.

In the above values: 

- `"2"` will be converted to `2`.
- `true` will be converted to `1`.
- `"yes"` & `"no"` will be skipped.

After converting, The sum will be calculated. In this case, the sum will be `4` (`1` + `2` + `1`).

What is the array_sum method in PHP?

array_sum in PHP calculates the sum of numeric elements in an array and converts values where possible, skipping non-numeric ones. Empty arrays return zero.
