accidentally my site url has been changed and im unable to login to wp-admin

when i copy paste

define(‘WP_HOME’,’http://example.com’);
define(‘WP_SITEURL’,’http://example.com’);

to the site wp-config i dont find any difference

and when i edited the functions.php of the current theme with these lines

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

im unable to open the site and this error is coming

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/content/74/8868374/html/wp-content/themes/iGaming/functions.php on line 5

when i see the functions.php the first 10 lines are like this

<?php
update_option(‘siteurl’,’http://cazzeltech.com&#8217;);
update_option(‘home’,’http://cazzeltech.com);
require_once TEMPLATEPATH . ‘/lib/Themater.php’;
$theme = new Themater(‘iGaming’);
$theme->options[‘includes’] = array(‘featuredposts’);

$theme->options[‘plugins_options’][‘featuredposts’] = array(‘image_sizes’ => ‘615px. x 300px.’, ‘speed’ => ‘400’, ‘effect’ => ‘scrollHorz’);
