DB::getQueryLog() Returns Empty Array: How to Enable Query Logging in Laravel 5

When attempting to view query logs using DB::getQueryLog(), you may encounter an empty result array. This is due to query logging being disabled by default in Laravel 5.

To resolve this issue, you must first enable query logging by calling:

DB::enableQueryLog();

Alternatively, you can register an event listener as follows:

DB::listen(
    function ($sql, $bindings, $time) {
        // Perform necessary actions based on the query information
    }
);

Once enabled, you can retrieve the query log using DB::getQueryLog().

Tips:

• Multiple DB Connections: Specify the connection you wish to log queries for using DB::connection('connection_name')->enableQueryLog().
• Middleware for Query Logging: Enable query logging in a middleware's handle method and retrieve logs in the terminate method.
• Memory Management: Enable query logging only when necessary, especially for debugging purposes, to avoid excessive memory usage.
