How can PHP developers ensure that all values in an array are included or excluded in a calculation based on specific criteria?

To ensure that all values in an array are included or excluded in a calculation based on specific criteria, PHP developers can use array_filter() function. This function filters elements of an array using a callback function, which determines whether a value should be included or excluded based on the criteria provided. By defining the criteria in the callback function, developers can control which values are included in the calculation.

// Example of including values in the calculation based on a specific criteria
$array = [1, 2, 3, 4, 5];
$filteredArray = array_filter($array, function($value) {
    // Include values greater than 2 in the calculation
    return $value > 2;
});

// Calculate the sum of filtered values
$sum = array_sum($filteredArray);
echo $sum;
