PHP is a scripting language widely used in network development. It has the advantages of being easy to learn, flexible syntax, and highly portable. In PHP, using a for loop combined with an array to sum is a common operation. . The following is a detailed introduction to how to use for to find the sum of an array through example code.

Suppose we have an array $numbers, which contains 10 integers. We require the sum of this array. At this time, we can use a for loop to achieve this function.

First we need to define a variable $sum to store the sum of the array and initialize it to 0:

$sum = 0;

Then we use a for loop to traverse Array, starting from the first element and accumulating to the last element, as follows:

for($i = 0; $i < count($numbers); $i ){

}
echo "array The sum is: ". $sum;
?>
