Parse error: syntax error, unexpected T_VARIABLE in

I’m trying to insert the following code into a post:

<?php
$my_id = 1149
$post_id_1149 = get_post($my_id);
$content = $post_id_1149->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
echo $content;
?>

So, I entered the following into the ‘text’ field:

[insert_php]
$my_id = 1149
$post_id_1149 = get_post($my_id);
$content = $post_id_1149->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
echo $content;
[/insert_php]

The code is supposed to populate the ‘body text’ of the page with the contents of post_id_1149. The code is ‘good’ – i.e. if added to page.php it does what it is supposed to do. However, I’m trying to auto-populate the mobile version of the site using the content of the desktop version. That way, I only have to update the desktop version and the mobile version should automatically reflect any updates.

Unfortunately, I’m getting the following error:

Parse error: syntax error, unexpected T_VARIABLE in /.../plugins/insert-php/insert_php.php(48) : eval()’d code on line 3

Am I doing something wrong?
