Executing Multiple MySQL Queries in PHP: Syntax Error Resolution

In PHP, executing multiple MySQL queries using the mysqli extension can be achieved by using the multi_query() method. However, errors can arise when attempting to use this method, such as syntax errors.

To resolve syntax errors like the one encountered in the provided code snippet, avoid running multiple queries in a single statement. Separate each query into its own statement and execute them individually. Consider using a loop or array to iterate through each query and execute them one at a time. Here's a revised PHP code that demonstrates this approach:

<?php // Establish database connection (assume this function exists)
$conn = db_connect();

// Define the queries as an array
$queries = [
  "CREATE TEMPORARY TABLE tmp SELECT * FROM event_categoriesBU WHERE id = 1",
  "UPDATE tmp SET>

This approach ensures that each query is executed separately, allowing for error handling and ensuring that the success of one query does not depend on the previous ones. Additionally, it resolves the syntax error issue encountered when using the multi_query() method.
