How does the use of foreach differ from using a for loop when iterating over arrays in PHP, and why is one preferred over the other in certain situations?

When iterating over arrays in PHP, using a foreach loop is often preferred over a for loop because it simplifies the syntax and makes the code more readable. foreach automatically handles the iteration over each element in the array without the need for manual indexing or counting. However, a for loop may be preferred when you need to access the index of the array element or if you need more control over the iteration process. 

// Using foreach loop to iterate over an array
$colors = ["red", "green", "blue"];
foreach ($colors as $color) {
    echo $color . "<br>";
}

// Using for loop to iterate over an array
$colors = ["red", "green", "blue"];
for ($i = 0; $i < count($colors); $i++) {
    echo $colors[$i] . "<br>";
}
