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 postgres
amphp/postgres
AMPHP is a collection of event-driven libraries for PHP designed with fibers and concurrency in mind.
amphp/postgres is an asynchronous Postgres client.
The library implements concurrent querying by transparently distributing queries across a scalable pool of available connections. Either ext-pgsql (bundled with PHP) or pecl-pq are required.
Features
- Exposes a non-blocking API for issuing multiple Postgres queries concurrently
- Transparent connection pooling to overcome Postgres' fundamentally synchronous connection protocol
- Support for parameterized prepared statements
- Nested transactions with commit and rollback event hooks
- Unbuffered results to reduce memory usage for large result sets
- Support for sending and receiving notifications
Installation
This package can be installed as a Composer dependency.
Requirements
Note: pecl-ev is not compatible with ext-pgsql. If you wish to use pecl-ev for the event loop backend, you must use pecl-pq.
Documentation & Examples
Prepared statements and parameterized queries support named placeholders, as well as ? and standard numeric (i.e. $1) placeholders.
Row values are cast to their corresponding PHP types. For example, integer columns will be an int in the result row array.
More examples can be found in the examples directory.
