How Can I Execute Multiple MySQLi Queries Simultaneously in PHP?

Multiple mysqli Queries: Understanding mysqli_multi_query()

With MySQLi, executing multiple queries in a single request is not straightforward. Attempts to execute separate mysqli_query() calls will result in only the first query being executed. To overcome this limitation, mysqli_multi_query() provides a solution for executing multiple SQL statements in one go.

Example Implementation:

Consider the following scenario:

To execute both queries simultaneously, employ mysqli_multi_query():

Key Considerations:

• mysqli_multi_query() requires a string containing all queries separated by semicolons (;).
• mysqli_store_result() must be used to retrieve the results of each query. Since INSERT queries do not return result sets, check mysqli_error() for an empty string to confirm the insertion was successful.
• This approach is secure as it prevents SQL injections present in executing multiple mysqli_query() calls.
