How can I add all of my array values together in PHP?

Question

How can I add all of my array values together in PHP? Is there a function for this?

Answer 1

Let the given array values may contain integer or may not be. It would be better to have check and filter the values.

$array = array(-5, "  ", 2, NULL, 13, "", 7, "\n", 4, "\t",  -2, "\t",  -8);

// removes all NULL, FALSE and Empty Strings but leaves 0 (zero) values

$result = array_filter( $array, 'is_numeric' );
echo array_sum($result);
