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.

About
I make a web app in which my users can reorder before or after another.
I did not find any package to do what I search for, and since I use it at multiple place on my app I figured I would open source it in the hope it can help simplify the life of another developer out there!
Features
- Can reorder an item before or after another in a list of items
- Systematically "self-heals" the items orders by re-writing the index of all items starting from the minimum index
Requirements
- PHP >= 8.1
- Composer
Installation
In your terminal, on the root of your project folder, run:
Examples
- 1. Moving an item before another
- 2. Create a list of items out of any type
- 3. Find an item by its value
- 4. Create a listing from an array
- 5. Getting all items from a listing
- 6. Use a callback to apply the order on your value
- 7. Create a listing from values and specify how to retrieve the order using a callback
- 8. Specify how to match items together
1. Moving an item before another
In this example, we will move our book before our table.
2. Create a list of items out of any type
In this example, we will see that we can create a listing of anything, including objects.
3. Find an item by its value
In this example, we will see we can find an item by its "value" (the first parameter when creating a new instance of Item).
If the method finds no item matching the value, a ItemNotFoundException will be thrown.
You can also search by anything that can be checked using ===, including objects.
4. Create a listing from an array
In this example, we will create the listing from an array instead of manually pushing items.
5. Getting all items from a listing
In this example, we will get all items from a listing. Useful if you want to perform some task after reordering your items.
6. Use a callback to apply the order on your value
In this example, we will instruct the listing how it should set the order on our values. Useful if our values are objects holding their order. This saves you from looping again on all your objects.
This examples features an hypothetical Product Eloquent model.
7. Create a listing from values and specify how to retrieve the order using a callback
In this example, we will see how to create a listing out of an array of values, and using the second parameter to specify how to get the order from these values.
Useful if you have objects that already hold their own order, and you do not want to loop from them and create the Item by hand.
8. Specify how to match items together
In this example, we will instruct the listing how it should match our objects. Useful if your objects can contain different set of data, making the whole object different, when in reality both are equal (matching by id).
This examples features an hypothetical Product Eloquent model, where one of the two can have more attributes (like eager loaded relationships), making the triple equal check invalid.
