What are the advantages of using a foreach loop in PHP for iterating over data compared to a while loop?

When iterating over data in PHP, using a foreach loop is often more convenient and readable compared to a while loop. Foreach loops are specifically designed for iterating over arrays and objects, making the code more concise and easier to understand. Additionally, foreach loops automatically handle the iteration process, eliminating the need to manually manage an index variable as required in a while loop. 

// Using a foreach loop to iterate over an array
$colors = array("red", "green", "blue");

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