Are there any common pitfalls when using the fckeditor to edit automatically generated files in PHP?

One common pitfall when using the fckeditor to edit automatically generated files in PHP is that the editor may strip out necessary PHP code or break the formatting of the file. To solve this issue, you can use the htmlentities function to encode the PHP code before displaying it in the editor, and then decode it back to its original form before saving the file.

// Encode PHP code before displaying it in the fckeditor
$encoded_php_code = htmlentities($php_code);

// Display the encoded PHP code in the fckeditor
echo '<textarea name="editor_name">' . $encoded_php_code . '</textarea>';

// Decode the PHP code before saving the file
$decoded_php_code = html_entity_decode($_POST['editor_name']);

// Save the decoded PHP code to the file
file_put_contents('file.php', $decoded_php_code);
