What are the technical considerations when using file_get_contents to retrieve images from a remote server in PHP?

When using file_get_contents to retrieve images from a remote server in PHP, it is important to consider the memory usage and potential security risks. To mitigate these issues, you can use the "stream_context_create" function to set a timeout for the request and limit the amount of data read into memory. 

$url = 'https://example.com/image.jpg';
$context = stream_context_create([
    'http' => [
        'timeout' => 5 // Set timeout to 5 seconds
    ]
]);
$imageData = file_get_contents($url, false, $context);

if ($imageData !== false) {
    // Process the image data
} else {
    // Handle error
}
