What are the potential pitfalls of using arrays with specific indexes (0 and 1) for replacing smilies in PHP code?

Using specific indexes like 0 and 1 in arrays for replacing smilies in PHP code can lead to confusion and errors if the indexes are not properly managed. To avoid potential pitfalls, it's better to use associative arrays with descriptive keys for each smiley. This way, the code is more readable and maintainable. 

// Using associative arrays for smiley replacements
$smilies = array(
    ':)' => '😊',
    ':(' => '😞',
    ':D' => '😄',
    // Add more smiley replacements as needed
);

// Example of replacing smilies in a string
$text = "Hello, I'm feeling happy :) and sad :(";
foreach ($smilies as $smiley => $emoji) {
    $text = str_replace($smiley, $emoji, $text);
}

echo $text;
