How can server settings impact the handling of MIME types in PHP file uploads?

Server settings can impact the handling of MIME types in PHP file uploads by restricting the types of files that can be uploaded based on the server's configuration. To solve this issue, you can use the `$_FILES` superglobal array to check the MIME type of the uploaded file and validate it against a list of allowed MIME types. If the uploaded file's MIME type does not match any of the allowed types, you can reject the file upload. 

$allowedMimeTypes = ['image/jpeg', 'image/png', 'image/gif'];

if (in_array($_FILES['file']['type'], $allowedMimeTypes)) {
    // Process the file upload
} else {
    echo "Invalid file type. Only JPEG, PNG, and GIF files are allowed.";
}
