FAQ
Example:
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 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.
Informations about the package spy

Installation
How it works ?
Behind the scene:
The initial object will be copied with a specific cloner then value of the initial (copied) object and the manipulated (current) object will be compared on demand to check if there is some modifications.
Suppose you want to spy a foo object to know if it was modified :
-
Tag the class to spy with an interface that will correspond to the chosen cloner, there is 2 built-in cloners :
Eniams\Spy\Cloner\DeepCopyClonerInterfacethat use the famous library DeepCopy
or
Eniams\Spy\Cloner\SpyClonerLoadPropertyObjectInterfaceorEniams\Spy\Cloner\SpyClonerInterfacethat allows you to clone more deeper the object/array stored in properties
You can create a custom Cloner to copy your object :
- Create the Cloner that should implements
Eniams\Spy\Cloner\ClonerInterface. - Create an interface related to the created Cloner that should implements
Eniams\Spy\SpyInterface.
If you're using Symfony thanks to the autoconfigure tags you don't have to follow the next step, the created cloner will be
registered to the ChainCloner that is responsible to clone the oject to spy.
So you can go to step 3.
-
For Vanilla PHP if you don't want to use the default cloners you can Register yours in the
Eniams\Spy\ClonerChainCloner - Time to spy your object :shipit:
Now, you want to want to know if a specific property was modified and get the initial and the current value.
Working with Services container you can store an object in the SpyBase to retrieve it later in your application
Symfony
Vanilla PHP
For simple use case that don't need to clone an object, you can also check the difference between 2 "same" classes.
More advanced use case
You can define a context to check some properties.
You can define dynamically which properties to check
You can exclude some properties.
