php can use the "array_sum()" function to find the sum of array elements. The operation method is: 1. Create a PHP sample file; 2. Define an array "array" containing some integers; 3. Use " The "array_sum()" function performs a sum operation on the array and stores the result in the variable "sum"; 4. Echo prints out the variable "sum".

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.
