Message: file_get_contents(): https:// wrapper is disabled in the server configuratio

I am trying below code to get city detail from thirdparty website using one of my controller file

PHP Code:

$target_url = "https://ziptasticapi.com/{$zip}";
$cityInfo = file_get_contents($target_url, FILE_USE_INCLUDE_PATH); 


But I am getting below errors, I already tried allow_url_fopen = On & allow_url_include = On in php.ini file, it getting issue with php7.0 while I am using php 5.6 It works fine. So please let me guide its codeigniter issue or server? I am using same above code in external file than it works fine, but while I am using above code with controller it gives error with php7.0.
