Are there specific PHP configurations or settings in the php.ini file that could affect the functionality of functions like get_headers() when used on a server?

The issue with functions like get_headers() not working on a server could be due to the 'allow_url_fopen' setting in the php.ini file being disabled. To solve this issue, you need to enable the 'allow_url_fopen' setting in the php.ini file. 

// Enable allow_url_fopen setting in php.ini
ini_set('allow_url_fopen', 1);

// Now you can use functions like get_headers() to fetch headers from URLs
$headers = get_headers('https://example.com');
print_r($headers);
