Why does the PHP function include() generate warnings when trying to include a file from a URL?

The PHP function include() generates warnings when trying to include a file from a URL because it poses a security risk by allowing remote file execution. To solve this issue, you can use the file_get_contents() function to retrieve the contents of the URL and then use eval() to execute the code. 

<?php
$url = 'http://example.com/file.php';
$content = file_get_contents($url);
eval("?>" . $content);
?>
