How can the shorthand operator "+=" be utilized in PHP for incrementing values during repetitive calculations?

When performing repetitive calculations in PHP, the shorthand operator "+=" can be used to increment values quickly and efficiently. Instead of writing out the full syntax of adding a value to a variable, the "+=" operator combines the addition and assignment into a single step. This can streamline code and make it easier to read and maintain. 

// Example of utilizing the "+=" shorthand operator for incrementing values
$sum = 0;

for ($i = 1; $i <= 10; $i++) {
    $sum += $i;
}

echo $sum; // Output: 55 (1 + 2 + 3 + ... + 10)
