find the sum of all values in a map in php

To find the sum of all values in a map or an associative array in PHP, you can use the array_sum() function. This function takes an array as an argument and returns the sum of all its values.

Here's an example code snippet:

main.php
$map = array(
    "foo" => 1,
    "bar" => 2,
    "baz" => 3,
    "qux" => 4
);

$sum = array_sum($map);
echo "Sum of all values in the map is: " . $sum;
154 chars
10 lines

Output:

main.php
Sum of all values in the map is: 10
36 chars
2 lines

In the above example, we have defined a map or an associative array with keys "foo", "bar", "baz", and "qux" with corresponding values 1, 2, 3, and 4. We have then used the array_sum() function to find the sum of all values in the map, which is 10. Finally, we have printed the result using the echo statement.
