Optimize Database Queries:

When interacting with a database in PHP applications, optimize your queries to ensure efficient data retrieval and manipulation. Techniques include:

• Indexing: Use appropriate indexes on columns frequently used in WHERE clauses to speed up query execution.
• Avoid SELECT *: Instead of selecting all columns from a table, specify only the required columns to reduce data transfer overhead.
• Use Joins Wisely: Minimize the number of joins and use INNER JOIN, LEFT JOIN, or RIGHT JOIN based on your requirements.
• Limit and Pagination: When dealing with large datasets, implement limit and pagination techniques to fetch data in smaller, manageable chunks.
