如果您使用的不是Laravel，而是Elquent包，那么：

use \Illuminate\Database\Capsule\Manager as Capsule;
use \Illuminate\Events\Dispatcher;
use \Illuminate\Container\Container;

$capsule = new Capsule;

$capsule->addConnection([
    // connection details
]);
// Set the event dispatcher used by Eloquent models... (optional)
$capsule->setEventDispatcher(new Dispatcher(new Container));

// Make this Capsule instance available globally via static methods... (optional)
$capsule->setAsGlobal();

// Setup the Eloquent ORM...(optional unless you've used setEventDispatcher())
$capsule->bootEloquent();

// Listen for Query Events for Debug
$events = new Dispatcher;
$events->listen('illuminate.query', function($query, $bindings, $time, $name)
{
    // Format binding data for sql insertion
    foreach ($bindings as $i => $binding) {
        if ($binding instanceof \DateTime) {
            $bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
        } else if (is_string($binding)) {
            $bindings[$i] = "'$binding'";`enter code here`
        }
    }

    // Insert bindings into query
    $query = str_replace(array('%', '?'), array('%%', '%s'), $query);
    $query = vsprintf($query, $bindings);

    // Debug SQL queries
    echo 'SQL: [' . $query . ']';
});

$capsule->setEventDispatcher($events);

在我看来，这将是初学者的最佳方法：

echo "<pre>";
print_r($query->toSql());
print_r($query->getBindings());

这里也描述了这一点。https://stackoverflow.com/a/59207557/9573341

将此代码添加到AppServiceProvider并获取日志文件

         \DB::listen(function ($query) {
             \Log::info(
                 $query->sql,
                 $query->bindings,
                 $query->time
             );
         });

你可以使用发条

Clockwork是一个用于PHP开发的Chrome扩展，通过一个新面板扩展了Developer Tools，该面板提供了用于调试和分析PHP应用程序的各种信息，包括请求、标头、获取和发布数据、cookie、会话数据、数据库查询、路由、应用程序运行时可视化等信息。

但也适用于firefox

打印上次查询

DB::enableQueryLog();

$query        = DB::getQueryLog();
$lastQuery    = end($query);
print_r($lastQuery);

使用debugbar包

composer require "barryvdh/laravel-debugbar": "2.3.*"
