FAQ
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.

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.
Curse - Cursor reader for cursed PostgreSQL's functions
If you have large result sets returned by a PostgreSQL's function maybe is time to return a cursor and try this tiny library to help you out.
How to use it
Composer installation coming soon!
This component was made to use its own connection (You need to have a own transaction in order to use cursors in PostgreSQL) so you will need to use the component's (a wrapper for PDO with less methods and functionality) or create your own implementation of (for using Doctrine's DBAL, for example).
Note that the component will not declare a cursor for your query or something like that (although this will be done soon) it was made to take a function that returns a cursor. That said let's see some code (I will skip connection part because it is really, really simple).
will not rewind or store results it will just go on forward until it returns null (I know this is not good) to signal that there are no more rows to read.
Since it uses its own connection and will "close" (commit the transaction and close the connection) to avoid a high number of connections in your database.
Composer command for our command line client (download client)This client runs in each environment. You don't need a specific PHP version etc. The first 20 API calls are free.Standard composer command
