Hi i am a new bee to wordpress i need to know that how can i write a simple wordpress plugin with a page option in wordpress.

Use the below code for changing the admin footer text dynamically.
Save the below code as a .php file in your wordpress plugins directory.

register_deactivation_hook( __FILE__, 'footer_word_remove' );

function footer_word_install() {
    add_option("footer_word_data", 'Default', '', 'yes');

function footer_word_remove() {

if (is_admin()) {
    add_action('admin_menu', 'footer_word_admin_menu');
    function footer_word_admin_menu() {
        add_options_page('footer word', 'footer word', 'administrator',
    'footer-world', 'footer_word_html_page');

function footer_word_html_page() {
    <h2>footer_word Options</h2>
    <form method="post" action="options.php">
    <?php wp_nonce_field('update-options'); ?>
    <table width="510">
    <tr valign="top">
    <th width="92" scope="row">Enter Text</th>
    <td width="406">
    <input name="footer_word_data" type="text" id="footer_word_data" value="<?php echo get_option('footer_word_data'); ?>" />
    <input type="hidden" name="action" value="update" />
    <input type="hidden" name="page_options" value="footer_word_data" />
    <input type="submit" value="<?php _e('Save Changes') ?>" />

function change_footer_admin() {
    echo get_option('footer_word_data');

add_filter('admin_footer_text', 'change_footer_admin');
