What are the benefits of using foreach() loops over while() loops in PHP when iterating through arrays?

When iterating through arrays in PHP, using foreach() loops is generally more concise and readable than while() loops. foreach() loops automatically handle array keys and values, making it easier to access and work with array elements. Additionally, foreach() loops are less error-prone as they handle the internal array pointer automatically, whereas while() loops require manual management of the pointer. 

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

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