What is the purpose of using PHP foreach loop with an array in the given code snippet?

In the given code snippet, the purpose of using a PHP foreach loop with an array is to iterate over each element in the array and perform a certain operation on each element. This is a common practice when you need to process each element of an array individually without having to manually write code for each element. Code snippet: 

```php
$colors = array("red", "green", "blue");

foreach ($colors as $color) {
    echo $color . "<br>";
}
```

In this code snippet, the foreach loop iterates over the $colors array and prints each color on a new line. This allows for easy processing of each element in the array without the need for manual indexing or iteration.
