What is the significance of the allow_url_fopen setting in PHP when using functions like file_get_contents?

The allow_url_fopen setting in PHP determines whether PHP scripts can open remote files using functions like file_get_contents. If this setting is disabled, attempting to use file_get_contents with a URL will result in an error. To fix this issue, you can enable the allow_url_fopen setting in your php.ini file or use a different method to fetch the remote content, such as cURL. 

// Enable allow_url_fopen setting in PHP
ini_set('allow_url_fopen', 1);

// Now you can safely use file_get_contents with URLs
$content = file_get_contents('https://example.com');
echo $content;
