Minimal PHP framwork

Concept

General idea

This minimal framework is meant to be used for a Model & Manager PHP based application.

• Model: class that represents one key data object of your application
• Manager: singleton class managing all instances of one model

If your application is about cars, you could have the following classes and methods:

With the framework

This minimal framework defines two classes for you: AbstractModel and AbstractManager. Both predefine methods that every model and manager need, like Manager.find(int), Manager.findAll(), Model.getId(), Model.insert(), etc. (please find all defined methods in Methods list down below).

This framework makes data persistence easy by using properties and class names to match database table names. For example, if a model is named AwesomeCar the framework will look for a table named awesome_car.

How to install

This project is available as a Composer dependency. Please use the following command:

How to use

At the beginning of your application, please set the PDO connection in the model and manager like this:

This will allow the model to update and insert itself into the database, and the manager to find models (from an ID for example). Plus, all your models and manager will be able to easily access database.

Then simply make all your models and managers inherit from Gaetanroger\MinimalPhpFramework\AbstractModel and Gaetanroger\MinimalPhpFramework\AbstractManager. Be careful to follow naming conventions specified down below, as names are by default dynamically used by the framework.

Conventions to follow

Model

• A model class name must use CamelCase;
• A model class name should not end with Model (except if it is part of the actual model name);
• The model class name must be the exact conversion from snake_case to CamelCase of the table name.

Valid model names with their table name:

Invalid model names:

Manager

• A manager class name must use CamelCase;
• A manager class name must end with Manager;
• A manager class name must not contain Manager anywhere else;
• The manager class name must be identical with the model name plus the word Manager.

Valid manager names with their model name:

Invalid manager names:

Properties and methods list

AbstractModel

• $id: ID of the model. The database field must be set to auto increment, as the framework uses this value to check if the model is already inserted into database or not.
• insert(): Create a now row in the table named after the model class by using the model properties as field names.
• update(): Same as insert() but updates the fields values of the row matching the model ID.
• delete(): Delete the table row matching the model ID.
• getId(): Returns model's ID.
• getTableName(): Returns the model table name by converting the class name to snake_case. This method can be overridden if a custom table name must be used.

AbstractManager

• find(id): Returns the model matching the ID from database. If no model matches, an exception is thrown.
• findWhere(conditions): Returns the model filling the conditions. All the conditions are strict equality checks (= sign). If a different condition check is necessary, feel free to implement a new method.
• findAll(): Returns all models managed by this manager.
• getTableName(): Returns the model table name by converting the class name (without the word Manager) to snake_case. This method can be overridden if a custom table name must be used.
• getModelName(short): Returns the model name by trimming the word Manager from the class name. If short is false, will return full class name (package/model). This method can be overridden if a custom manager name must be used.
• count(column, distinct): Counts rows in table using SQL COUNT. Default parameters will simply count all rows but you can specify what column you want to count and if you want it to only count distinct values.
