How Can I Inspect the Final Parametrized SQL Query Executed by PDO in PHP?

Inspecting the Parametrized SQL Query in PHP with PDO

When utilizing PDO in PHP to interface with a MySQL database via parametrized queries, the question of how to verify the final SQL query arises. This is due to the separation of the query template and parameter values during query execution.

While the underlying database possesses the complete SQL query, PHP does not maintain a copy of it. As suggested by Ben James, retrieving the exact query from the PHP side is not feasible.

An alternative approach involves logging all SQL queries to observe the commands executed on the server. In the case of MySQL, this can be accomplished by updating the my.cnf (or my.ini) configuration file and appending a line like:

log=[REPLACE_BY_PATH]/[REPLACE_BY_FILE_NAME]

However, it's crucial to emphasize that this method is only suitable for testing environments and should not be employed in live production systems.
