Wordpress Migration error phpupdate_option is not a function

Question

I'm trying to migrate my wordpress from a subfolde to the root. I've already done it from localhost to the subfolder with the same method

update_option('siteurl','http://example.com/blog');
update_option('home','http://example.com/blog');

But this time it does not look to work... It says "Call to undefined function phpupdate_option() in functions.php line 1.

In config.php there is no url define().

Is there someone who had a solution for it?

Thanks in advance.

Answer 1

It sounds like your opening <?php tag is abutting your first call to update_option. If it isn't directly adjacent to it, perhaps the whitespace between the two is unrecognized for one reason or another (this can happen from copying and pasting from some sources). Have your functions.php file start off like this:

<?php

update_option('siteurl','http://example.com/blog');
update_option('home','http://example.com/blog');

Answer 2

You can change it from database also. In database there is wp_options table and these two fields present in this table.
