parsing error after adding php filter and unable to edit site

Hello,
I was attempting to edit titles per this link:

https://presscustomizr.com/snippet/setting-custom-titles-featured-pages/

and received this error:

Parse error: syntax error, unexpected ‘s’ (T_STRING), expecting ‘)’ in /home/content/p3nexnas06_data02/71/2159571/html/wp-content/themes/customizr-child/functions.php on line 59

I am now unable to access the site at all.

The filter I added and customized:

add_filter('tc_fp_title' , 'my_custom_fp_titles', 10 ,3);
function my_custom_fp_titles( $original_title , $fp_id = null , $page_id = null ) {

    //assigns a custom title by page id
    $custom_title = array(
        //page id => 'Custom title'
        54 => 'More than just translation',
        57 => 'My background',
        60 => 'Contact me'
    );

    //if no custom title is defined for the current page id, return original
    if ( ! isset($custom_title[$page_id]) )
        return $original_title;

    return $custom_title[$page_id];
}

I’m brand new to this, any help i appreciated.
