After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

# LARAVEL WHERE HAS IN

Build Status StyleCI

Laravel wherehasin是一个可以提升Laravel ORM关联关系查询性能的扩展包，可以替代Laravel ORM中的whereHas以及whereHasMorphIn查询方法。

环境

安装

简介

Laravel的关联关系查询whereHas在日常开发中给我们带来了极大的便利，但是在主表数据量比较多的时候会有比较严重的性能问题，主要是因为whereHas用了where exists (select * ...)这种方式去查询关联数据。

通过这个扩展包提供的whereHasIn方法，可以把语句转化为where id in (select xxx.id ...)的形式，从而提高查询性能，下面我们来做一个简单的对比：

当主表数据量较多的情况下，where id in会有明显的性能提升；当主表数据量较少的时候，两者性能相差无几。

主表test_users写入130002条数据，关联表test_user_profiles写入1002条数据，查询代码如下

最终耗时如下，可以看出性能相差还是不小的，如果数据量更多一些，这个差距还会更大

使用

whereHasIn

此方法已支持Laravel ORM中的所有关联关系，可以替代whereHas

orWhereHasIn

多级关联关系

需要注意的是，如果是BelongsTo类型的关联关系，使用whereHasIn时使用的不是主键，而是外键

whereHasMorphIn

此方法已支持Laravel ORM中的所有关联关系，可以替代whereHasMorph
