Are there specific considerations or limitations when using file_get_contents() to retrieve content from certain websites, such as Google?

When using file_get_contents() to retrieve content from certain websites like Google, you may encounter limitations due to security measures such as SSL/TLS encryption or user-agent restrictions. To overcome these limitations, you can set a custom user-agent header in the HTTP request to mimic a browser's behavior and avoid being blocked. 

$url = 'https://www.google.com';
$options = array(
    'http' => array(
        'method' => 'GET',
        'header' => 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'
    )
);
$context = stream_context_create($options);
$content = file_get_contents($url, false, $context);

echo $content;
