Propel is an open-source object-relational mapping (ORM) for PHP 5. It allows you to access your database using a set of objects, providing a simple API for storing and retrieving data. There are two major versions, 1 and 2.
Propel is an open-source object-relational mapping (ORM) for PHP 5.
It allows you to access the records in your database using a set of OOP objects, providing a simple API for basic CRUD operations. To accomplish this, Propel ORM includes a generator component which uses source code generation to build PHP classes based on a data model definition written in XML (or reverse-engineered from an existing database).
Propel also includes a runtime component which manages connections, transactions, and any idiosyncratic rules that describe the workings of the RDBMS being used with Propel.
In addition to being open source, the code as implemented in a project is extendable with behaviors which alter the generated class structure and by working with the one-time generated model classes themselves which extend the base Active Record classes.
It is also an integral part of the PHP framework Symfony and was the default ORM up to and including version 1.2.
