In PHP, you can use the array_sum() function to calculate the sum of array elements. 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 calculate the sum of array elements:

<?php
$array = array(1, 2, 3, 4, 5);
sum=arraysum(sum = array_sum(sum=arraysum(array);
echo "数组元素的和为：" . $sum;
?>

The output result is:

数组元素的和为：15

In the above example, we defined a An array array containing some integers. Then, we use the array_sum() function to perform a sum operation on the array array and store the result in the variable $sum.

Finally, we use the echo statement to print out the sum of the array elements.

Note that the array_sum() function can only be used to calculate the sum of the elements of an array containing numeric values. If the array contains non-numeric elements, they are treated as 0 for calculations. Before calculating the sum of array elements, make sure that all elements in the array are of numeric type.
