Below is the translation of your PHP code snippet into English, with proper formatting and corrections for syntax issues. Note that the `ereg()` function is deprecated as of PHP 5.3 and removed in PHP 7.0. It's recommended to use `preg_match()` instead.
Here’s the corrected and translated version:
```php
```
### Explanation:
1. **`ereg()` to `preg_match()`**: The `ereg()` function has been replaced with `preg_match()`, which is the modern alternative for regular expression matching in PHP.
2. **Regular Expression**: The regex pattern `/^[a-z]([a-z0-9]*[-_\.]?[a-z0-9]+)*@([a-z0-9]*[-_]?[a-z0-9]+)+[\.][a-z]{2,3}([\.][a-z]{2})?$/i` is used to validate the email format:
- It ensures the email starts with a lowercase letter.
- Allows alphanumeric characters, dots (`.`), underscores (`_`), and hyphens (`-`) before the `@` symbol.
- Ensures a valid domain name after the `@` symbol.
- Requires a top-level domain (TLD) of 2 or 3 characters, optionally followed by another TLD (e.g., `.co.uk`).
- The `i` flag makes the match case-insensitive.
3. **Output**:
- If the email matches the pattern, it outputs: `"Your email address is correct!"`.
- Otherwise, it outputs: `"Please try again!"`.
