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. You can look here for more information.

  • 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 datum-php

datum-php

Simple (as in VERY simple) database abstraction layer

Basic usage

First require biohzrdmx/datum-php with Composer.

Then create a Database instance, to call the constructor you will need an AdapterInterface implementation instance; there are two adapters included: MySQLAdapter and SQLiteAdapter, both of which extend from PDOAdapter:

Or using SQLite:

Simple queries

To run a simple query use the query method:

For INSERT statements you can easily get the auto-increment ID with the lastInsertId method:

If you need to do more complex stuff, you may pass a Closure as the third argument, to manipulate the PDOStatement object directly:

Selecting data

To retrieve data from the database, use the select method:

If you need to pass parameters, pass an array as the second argument:

Named parameters are supported too:

To retrieve just one row, use the first method:

You can also query single, scalar values with the scalar method:

Chunking is also possible by means of the chunk method:

Just pass the number of rows per chunk, the query, its parameters as an array and a Closure that will be executed for each chunk, and that receives the $rows.

Transactions

Automatic transactions are supported, if the query generates an error the transaction will be rolled-back automatically, otherwise it will commit.

To use them, call the transaction method:

Pass a Closure, inside it you will call your queries by using the $database argument that it receives.

You can also use manual transactions with the begin, commit and rollback methods:
