With() vs Compact() in Laravel

由 |▌冷眼眸甩不掉的悲伤 提交于 2021-02-20 10:12:41
问题 Is there any difference between with() and compact() ? Which one is more efficient ? 回答1: with() is a Laravel function and compact() is a PHP function and have totally different purposes. with() allows you to pass variables to a view and compact() creates an array from existing variables given as string arguments to it. See compact() for more info on this matter. 回答2: with() is a method made available by method from one of their classes while compact() is a method that is available by default

Laravel command cannot call $this->info() in child class

由 徘徊边缘 提交于 2021-02-20 06:07:06
问题 I'm just starting out with the basic concepts OO in PHP, Foo.php class Foo extends Command { public function __construct() { parent::__construct(); } public function fire() { $bar = new Bar(); } } Bar.php class Bar extends Foo { public function __construct() { parent::__construct(); $this->info('Bar'); } } When I run Foo::fire() it gives: Call to undefined method Foo::__construct() . But Foo clearly has a constructor, what am I doing wrong? Another thing I suspect is that it might be a

Laravel viaRemember always returning false

由 余生颓废 提交于 2021-02-20 04:16:14
问题 I've had trouble with keeping my users logged in, so I did some testing and I noticed that the function viaRemember always returns false . This is my login controller function with all the irrelevant code stripped off: public function postSignin(Request $request, AppMailer $mailer) { $this->validate($request, [ 'email' => 'required', 'password' => 'required', ]); $username = $request->get('email'); $password = $request->get('password'); $field = filter_var($username,FILTER_VALIDATE_EMAIL)?

Laravel 5.7 Send an email verification on newly created user

由 这一生的挚爱 提交于 2021-02-20 04:07:55
问题 Based on this documentation you can easily create a user email verification when someone signing up by them self, but how to send an email verification when admins created the account for their users?

面试官问：你说说Redis的几个过期策略？

由 这一生的挚爱 提交于 2021-02-19 10:47:41
在使用redis时，一般会设置一个过期时间，当然也有不设置过期时间的，也就是永久不过期。当设置了过期时间，redis是如何判断是否过期，以及根据什么策略来进行删除的。 设置过期时间 expire key time(以秒为单位) 这是最常用的方式 setex(String key, int seconds, String value) 字符串独有的方式 除了字符串自己独有设置过期时间的方法外，其他方法都需要依靠expire方法来设置时间如果没有设置时间，那缓存就是永不过期如果设置了过期时间，之后又想让缓存永不过期，使用persist key 三种过期策略 定时删除 在设置key的过期时间的同时，为该key创建一个定时器，让定时器在key的过期时间来临时，对key进行删除 优点： 保证内存被尽快释放 缺点： 若过期key很多，删除这些key会占用很多的CPU时间，在CPU时间紧张的情况下，CPU不能把所有的时间用来做要紧的事儿，还需要去花时间删除这些key 定时器的创建耗时，若为每一个设置过期时间的key创建一个定时器（将会有大量的定时器产生），性能影响严重 懒汉式式删除 key过期的时候不删除，每次通过key获取值的时候去检查是否过期，若过期，则删除，返回null。 优点： 删除操作只发生在通过key取值的时候发生，而且只删除当前key，所以对CPU时间的占用是比较少的
