laravel 打印完整sql语句

1.使用toSql()方法

2.用DB自带的getQueryLog方法直接打印：

use Illuminate\Support\Facades\DB;
 
1 DB::connection()->enableQueryLog();  // 开启QueryLog
 \App\User::find(1);
 dump(DB::getQueryLog());exit;

得到的结果语句与参数是分开的，非常不方便验证

array:1 [
   0 => array:3 [
     "query" => "select * from `fook_platform_ordercode` where `fook_platform_ordercode`.`id` = ? limit 1"
     "bindings" => array:1 [
       0 => 1
     ]
     "time" => 11.47
   ]
 ]

3.(推荐使用)打印出完整的sql语句，可将以下代码复制到AppServiceProvider中的boot方法中：

 \DB::listen(
     function ($sql) {
         foreach ($sql->bindings as $i => $binding) {
             if ($binding instanceof \DateTime) {
                 $sql->bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
             } else {
                 if (is_string($binding)) {
                     $sql->bindings[$i] = "'$binding'";
                 }
             }
         }
 
         // Insert bindings into query
         $query = str_replace(array('%', '?'), array('%%', '%s'), $sql->sql);
 
         $query = vsprintf($query, $sql->bindings);
 
         // Save the query to file
         $logFile = fopen(
             storage_path('logs' . DIRECTORY_SEPARATOR . date('Y-m-d') . '_query.log'),
             'a+'
         );
         fwrite($logFile, date('Y-m-d H:i:s') . ': ' . $query . PHP_EOL);
         fclose($logFile);
     }
 );
