How can PHP beginners effectively approach tasks like finding the largest value in an array without relying on built-in functions?

When finding the largest value in an array without relying on built-in functions, beginners can iterate through the array and compare each element to a variable that stores the current largest value. If an element is greater than the current largest value, update the variable with the new value. This approach allows beginners to understand the logic behind finding the largest value in an array without using built-in functions. 

$numbers = [3, 7, 2, 8, 5];
$largest = $numbers[0];

foreach ($numbers as $num) {
    if ($num > $largest) {
        $largest = $num;
    }
}

echo "The largest value in the array is: " . $largest;
