What are the limitations of using include to embed content in PHP in terms of size restriction?

When using the include function in PHP to embed content, there is a limitation on the size of the file that can be included. This limitation is typically imposed by the server configuration settings and can cause issues if the included file exceeds the size limit. To solve this issue, one possible solution is to use the file_get_contents function to read the contents of the file and then echo or output the contents directly.

$content = file_get_contents('large_file.php');
echo $content;
