Why Is My foreach Modifying the Original Array Not Working? | PHP Bug #20

Why are your array values not changing even after using a foreach loop?

In this PHP bug fix video, you'll learn why foreach doesn't modify the original array by default and how to use references correctly to update array values.

🐛 PHP Bug #20
Topic: foreach Not Modifying the Original Array

❌ Wrong:
foreach($prices as $price) {
$price = $price * 1.18;
}

✅ Correct:
foreach($prices as &$price) {
$price = $price * 1.18;
}
unset($price);

By default, foreach works on a copy of the value. To modify the original array, you need to pass the variable by reference using the & operator.
