How can I check the final SQL parametrized query in PHP with PDO?

Checking Final SQL Parametrized Query in PHP with PDO

When utilizing PDO (PHP Data Objects) with a MySQL database and parametrized queries, there is no straightforward method to inspect the final SQL query after parameters have been substituted. The reason for this is that the parametrized query and parameters are sent to the database independently. Only the database itself has access to the complete SQL statement.

Workaround Option

Although accessing the actual executed query from PHP is not possible, one workaround is to log all SQL queries on the database server. For MySQL, this can be achieved by appending a log statement to the my.cnf or my.ini configuration file:

log=[REPLACE_BY_PATH]/[REPLACE_BY_FILE_NAME]

Note: It's crucial to avoid running this configuration in a production environment to prevent potential security risks.
