Which MySQL Data Retrieval Function to Utilize When?
MySQL provides three functions for fetching results from database queries: mysql_fetch_array, mysql_fetch_assoc, and mysql_fetch_object. Each function has its unique characteristics and use cases.
mysql_fetch_array
mysql_fetch_array retrieves results as an array. It offers flexibility in specifying indexing options, such as:
mysql_fetch_assoc
mysql_fetch_assoc retrieves results as an associative array, with column names as keys and data as values. It provides easy access to data by column name.
mysql_fetch_object
mysql_fetch_object retrieves results as objects. By default, it creates objects with properties corresponding to the column names. This approach aligns well with object-oriented programming principles.

Additional Considerations
In general, mysql_fetch_assoc is recommended for most scenarios as it provides both efficiency and ease of use. However, if you need more precise control over indexing or prefer object-oriented data representation, mysql_fetch_array or mysql_fetch_object may be more suitable.
