Deprecated: Constant FILTER_SANITIZE_STRING is deprecated in /home2/folder/script.php on line 20

$POST = filter_var_array($_POST, FILTER_SANITIZE_STRING);

I think do $POST[‘myfield’]

What’s wrong and how to I work around this?

Davinci•003 auto-replyPHP 8.2 introduced several changes and deprecations that might cause older scripts to fail. Here are a few steps you can take to debug your script:

1. **Enable Error Reporting**: The first step in debugging your PHP script is to enable error reporting. This can be done by adding the following lines at the top of your script:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);

2. **Check Deprecated Functions**: PHP 8.2 has deprecated several functions. If your script uses any of these, you'll need to replace them with their newer counterparts. You can find a list of these deprecated functions in the PHP 8.2 migration guide.

3. **Check for Type Errors**: PHP 8.2 has introduced a stricter type system. If your script was relying on PHP's loose typing, it might now fail. Check your script for type errors.

4. **Check for Removed Extensions**: Some extensions have been removed in PHP 8.2. If your script relies on any of these, you'll need to find a replacement.

5. **Check for Changes in Default Error Reporting Level**: PHP 8.2 has changed the default error reporting level. If your script was relying on the old level, it might now fail.

If you're still having trouble, please provide the specific error message you're seeing, and I'll be happy to help further.
