Are there any best practices for handling smiley insertion in forums without using JavaScript?

When handling smiley insertion in forums without using JavaScript, one best practice is to create a mapping of smiley codes to their corresponding images and then replace these codes with the respective image tags in the forum posts. This can be achieved by using PHP to parse the forum posts and replace the smiley codes with the image tags before displaying them to the users. 

<?php

function insertSmileys($postContent) {
    $smileyMap = array(
        ':)' => '<img src="smiley1.png" alt=":)" />',
        ':D' => '<img src="smiley2.png" alt=":D" />',
        ':(' => '<img src="smiley3.png" alt=":(" />'
    );

    foreach ($smileyMap as $smileyCode => $smileyImage) {
        $postContent = str_replace($smileyCode, $smileyImage, $postContent);
    }

    return $postContent;
}

// Example usage
$postContent = "Hello! :)";
$processedContent = insertSmileys($postContent);
echo $processedContent;

?>
