laravel 框架下 使用mysql 批量添加数据

**批量添加数据**

`class Messages extends ChefModel {
//
protected $table = 'messages';

// 批量添加 性能更好，推荐使用
public static function batchAdd($data) {
DB::table('messages')->insert($data);
}


}

　　

实测，每次添加5000条数据时，速度最快

public function send($pushLog) {
$ftype = $pushLog->ftype;
$title = $pushLog->title;
$content = $pushLog->content;
$description = $pushLog->description;
$isAll = $pushLog->is_all;

$userIdArray = [];
if ($isAll == 1) {
$userIdArray = User::pluck("id");
} else {
$userIdArray = explode(",", $description);
}
$num = 5000; //分组，每次群发5000个用户，实测5000个速度最快
$group = [];
$created = Date("Y-m-d H:i:s", time());
$updated = Date("Y-m-d H:i:s", time());
Log::debug("groupdata start:" . Date("H:i:s", time()));
for ($i = 0; $i < count($userIdArray); $i++) {
$group[$i / $num][] = ['user_id' => $userIdArray[$i],
'title' => $title,
'remark' => $content,
'ftype' => 3, //系统消息
'created_at' => $created,
'updated_at' => $updated];
}
Log::debug("groupdata finish:" . Date("H:i:s", time()));
foreach ($group as $key => $data) {
Messages::batchAdd($data);
if ($isAll == 0) {
UserProfile::whereIn("user_id", array_column($data, 'user_id'))->increment("system_count");
}
}
if ($isAll == 1) {
UserProfile::increment("system_count");
}
Log::debug("adddata finish:" . Date("H:i:s", time()));
$pushLog->status = 1; // 发送成功
$pushLog->success_users = count($userIdArray);
$pushLog->updated_at = Date("Y-m-d H:i:s", time());
$pushLog->save();
}
