本文介绍了Laravel5.* 打印出执行的sql语句的方法,分享给大家,具体如下:

打开appProvidersAppServiceProvider.PHP,在boot方法中添加如下内容

5.2以下版本

// 先引入DB use DB;// 或者直接使用 DB:: DB::listen(function($sql, $bindings, $time) {        dump($sql);      });

5.2及以上版本

use DB;// 或者直接使用 DB::// 只能接受一个参数QueryExecuted {#84 ▼ +sql: "select * from `posts` where `slug` = ? limit 1" +bindings: array:1 [▶] +time: 0.59 +connection: MySqlConnection {#85 ▶} +connectionName: "mysql"} DB::listen(function($sql) {        dump($sql);        // echo $sql->sql;        // dump($sql->bindings);      });// 如果要放入日志文件中DB::listen(  function ($sql) {    // $sql is an object with the properties:    // sql: The query    // bindings: the sql query variables    // time: The execution time for the query    // connectionName: The name of the connection    // To save the executed queries to file:    // Process the sql and the bindings:    foreach ($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);  });
