    The comment_text() function in WordPress is used to display the text of the current comment in a theme template. Here's a detailed explanation of its function and usage:

    Function:

    comment_text( int|WP_Comment $comment_id, array $args = array() )
    

    Description:

    • comment_text() is a WordPress template tag that outputs the text of a comment.
    • It's often used within the WordPress Loop or a comment loop to display the content of each comment.
    • This function is a part of WordPress’s comment template tags, which are used to display comments and comment-related information on a post.

    Parameters:

    1. $comment_id (int|WP_Comment, optional):

      • This parameter can be either an integer (the ID of the comment) or a WP_Comment object.
      • If this parameter is not provided, the function will default to the current comment in the loop.
    2. $args (array, optional):

      • An associative array of arguments that can modify the function's output.
      • By default, it is an empty array.
      • These arguments are generally passed to control the markup or behavior of the comment text display.

    Related Function:

    • Walker_Comment::comment():
      • Walker_Comment::comment() is a method of the Walker_Comment class.
      • It is responsible for displaying a single comment by walking through each comment provided to it.
      • The comment_text() function is often used inside this method to render the text of each comment.

    Sample Usage:

    Here's an example of how comment_text() might be used in a WordPress theme:

    <?php
    // Loop through each comment
    foreach ( $comments as $comment ) {
        // Set the global comment variable
        $GLOBALS['comment'] = $comment;
    
        // Display the comment text
        comment_text();
    }
    ?>
    

    In this example, the function loops through each comment and displays its text. This is a simplified version of what might be found in a WordPress theme's comments template.

    Remember, comment_text() should be used within the context of a comment loop, and it relies on global variables set by WordPress during this loop. This makes it specific to the WordPress templating system and is primarily used for theme development.
