How can the code snippet be optimized for better performance and readability in PHP?

The code snippet can be optimized for better performance and readability in PHP by using the implode() function to concatenate the strings in the array. This will simplify the code and improve its efficiency. 

// Original code snippet
$colors = array('red', 'green', 'blue');
$output = '';
foreach ($colors as $color) {
    $output .= $color . ', ';
}
$output = rtrim($output, ', '); // Remove the last comma and space

// Optimized code snippet
$colors = array('red', 'green', 'blue');
$output = implode(', ', $colors);
