laravel 获取某个查询的查询SQL语句

DB::connection()->enableQueryLog();     //开启执行日志
$count = DB::table(‘test‘)              //执行查询
->whereNull(‘deleted_at‘)
->where(‘id‘, ‘=‘, 3)
->where(‘Name‘, ‘=‘, ‘测试‘)
->count();
print_r(DB::getQueryLog());             //获取查询语句、参数和执行时间

Array
(
    [0] => Array
        (
            [query] => select count(*) as aggregate from `test` where `deleted_at` is null and `id` = ? and `Name` = ?
            [bindings] => Array
                (
                    [0] => 3
                    [1] => 测试
                )
            [time] => 1
        )
)

$query = CdbForumSellthreadSearch::where($params)->orderBy("$orderby", "$ascDesc")->offset($start)->limit($limit);
$list = CdbForumSellthreadSearch::where($params)->orderBy("$orderby", "$ascDesc")->offset($start)->limit($limit)->get()->toArray();

//打印出的sql是预编译的sql语句，带有问号占位符的sql 
print_r($query->toSql());
echo ‘<pre>‘;

//下面打印出占位符对应的变量的值，数组里面的顺序和占位符的顺序是一致的
print_r($query->getBindings());
