What tools can be used to locate errors in PHP code that is dynamically generated at runtime?

One tool that can be used to locate errors in dynamically generated PHP code at runtime is the PHP function `error_log()`. By using this function, any errors or debugging messages can be logged to a specified file or system logger, making it easier to identify and troubleshoot issues in the code.

// Enable error logging
ini_set('display_errors', 0);
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');
```

Another tool that can be helpful is the PHP function `error_reporting()`, which allows you to set the level of error reporting for the script. By setting the error reporting level to `E_ALL`, you can ensure that all errors, warnings, and notices are displayed, helping to identify any issues in the dynamically generated code.

```php
// Set error reporting level
error_reporting(E_ALL);
