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 optimus
Optimus id transformation
With this library, you can transform your internal id's to obfuscated integers based on Knuth's integer hash. It is similar to Hashids, but will generate integers instead of random strings. It is also super fast.
Installation
Install using composer:
If you will be running your code on a 32 bit system or will be working with large prime numbers it is suggested that you install the GMP extension. For debian/ubuntu you can install the extension with one of these commands:
Usage
To get started you will need 3 things;
- Large prime number lower than
2147483647 - The inverse prime so that
(PRIME * INVERSE) & MAXID == 1 - A large random integer lower than
2147483647
Luckily for you, I have included a console command that can do all of this for you. To get started, just run the following command:
If you prefer to choose your own prime number (from this list for example), you can pass it to the command to calculate the remaining numbers:
Using those numbers, you can start creating instances of Optimus($prime, $inverted, $random):
NOTE: Make sure that you are using the same constructor values throughout your entire application!
Encoding and decoding
To encode id's, use the encode method:
To decode the resulting 1535832388 back to its original value, use the decode method:
Framework Integrations
Laravel
This is an example service provider which registers a shared Optimus instance for your entire application:
Once you have created the service provider, add it to the providers array in your config/app.php configuration file:
Laravel's automatic injection will pass this instance where needed. Example controller:
