How can the code snippet provided be improved for better readability and efficiency in PHP?

The code snippet can be improved for better readability and efficiency by using proper indentation, meaningful variable names, and avoiding unnecessary repetition. Additionally, using a foreach loop instead of a for loop can simplify the code and make it more readable. 

// Original code snippet
$colors = array("red", "green", "blue");
for ($i = 0; $i < count($colors); $i++) {
    echo $colors[$i] . "\n";
}

// Improved code snippet
$colors = array("red", "green", "blue");
foreach ($colors as $color) {
    echo $color . "\n";
}
