What are the implications of using reserved words like "LIMIT" in MySQL queries within PHP code, and how can they be addressed to avoid conflicts?
When using reserved words like "LIMIT" in MySQL queries within PHP code, conflicts can arise as these words have special meanings in SQL. To avoid issues, you can surround the reserved word with backticks (`) in your queries. This tells MySQL to treat it as a column or table name rather than a keyword.
$query = "SELECT * FROM table_name ORDER BY column_name LIMIT 10";
```
In the above example, "LIMIT" is a reserved word, so it should be enclosed in backticks to avoid conflicts:
```php
$query = "SELECT * FROM table_name ORDER BY column_name `LIMIT` 10";
