In PHP, you can use the array_sum() function to calculate the sum of an array. The array_sum() function accepts an array as a parameter and returns the sum of all elements in the array.

The following is a sample code that demonstrates how to use the array_sum() function to calculate the sum of an array:

The output result is:

数组的和为：15

In the above example, We define an array called numbers, which contains some numbers. We then call the array_sum function and pass the array as argument, saving the returned sum in the variable sum. Finally, we use echo to output the sum of the array.

You can modify the contents of the $numbers array according to your own needs. The array_sum() function will automatically calculate the sum based on the elements in the array.
