PHP array_sum() Function

It calculates the sum of values in an array and returns the sum of values in an array as an integer or float.

PHP versions prior to 4.2.1 modified the passed array itself and converted strings to numbers (which often converted them to zero, depending on their value)

Syntax

 array_sum(array) 

Example

$array=array(15,10,5);
echo array_sum($array);

Output

30

More Example

$array=array("a"=>10.2,"b"=>5,"c"=>0.9);
echo array_sum($array);

Output

16.1
