How to Avoid Syntax Errors When Executing Multiple MySQL Queries in PHP?

Using PHP to Execute Multiple MYSQL Queries: Syntax Errors

In PHP, executing multiple consecutive MySQL statements can be achieved using the multi_query() method. However, a common error occurs when attempting to combine multiple queries into a single string and execute them using the query() method.

Here's the corrected code:

include("databaseconnect.php");

$sqlQueries = [
    "CREATE TEMPORARY TABLE tmp SELECT * FROM event_categoriesBU WHERE id = 1",
    "UPDATE tmp SET>

Instead of concatenating the queries into a single string, this code uses an array to store each query. The loop iterates through the array and executes each query individually. This prevents syntax errors in the SQL statement.

Remember to handle errors properly using exception handling or by checking the $conn->error property after executing each query.
