Answer 1

Since strpos() will not work with multiple && OR || conditions, So you need to add ), strpos and !== false like below:

if (strpos($page_name_ulter, 'dissertation') !== false ||  strpos($page_name_ulter, 'vendor') !== false || strpos($page_name_ulter, 'js') !== false || strpos($page_name_ulter, 'css') !== false || strpos($page_name_ulter, 'bootstrap') !== false || strpos($page_name_ulter, 'CI3Xmuqx6MsCFcJf2wod6s0P9Q') !== false ||strpos($page_name_ulter, 'vendor') !== false || strpos($page_name_ulter, 'vendor') !== false || strpos($page_name_ulter, '=') !== false || strpos($page_name_ulter, 'essay?') !== false || strpos($page_name_ulter, 'input') !== false || strpos($page_name_ulter, 'main.js') !== false || strpos($page_name_ulter, 'main') !== false || strpos($page_name_ulter, 'php/js') !== false || strpos($page_name_ulter, '/') !== false || strpos($page_name_ulter, '.js') !== false || strpos($page_name_ulter, 'rating') !== false || strpos($page_name_ulter, 'intlTelInput') !== false || strpos($page_name_ulter, '.min') !== false || strpos($page_name_ulter, 'images') !== false) { return false; }

Note:- More better solution is using preg_match()
