README

Hector Schema is the schema generator module of Hector ORM. Can be used independently of ORM.

Installation

Composer

You can install Hector Schema with Composer, it's the recommended installation.

$ composer require hectororm/schema

Dependencies

• PHP ^8.0
• Packages dependencies:
  • hectororm/connection

DBMS compatibility

If you have any information on the compatibility of other versions, feel free to make a PR.

Usage

Generate a schema

use Hector\Connection\Connection;
use Hector\Schema\Generator\MySQL;

$connection = new Connection('...');
$generator = new MySQL($connection);

$schema = $generator->generateSchema('schema_name'); // Returns a `Hector\Schema\Schema` object
$container = $generator->generateSchemas('schema1_name', 'schema2_name'); // Returns a `Hector\Schema\SchemaContainer` object

Generators:

• Hector\Schema\Generato\MySQL for MySQL or derived DBMS
• Hector\Schema\Generato\Sqlite for Sqlite

Cache

This library don't provide cache management for schemas. It's to the user library to imagine how store the generated schema.

To help to do that, library only provide serialization of objects and restoration of inheritance between objects.

Schema

Description of classes represents the a schema.

Hector\Schema\SchemaContainer

It's a container of schema. Methods available:

• SchemaContainer::getSchemas(?string $connection = null): Generator Returns a generator of Hector\Schema\Schema objects, you can pass a specific connection
• SchemaContainer::hasSchema(string $name, ?string $connection = null): bool Check if container has a schema
• SchemaContainer::getSchema(string $name, ?string $connection = null): Schema Returns representation of a schema, an Hector\Schema\Schema object
• SchemaContainer::hasTable(string $name, ?string $schemaName = null, ?string $connection = null): bool Check if a schema in the container has a table
• SchemaContainer::getTable(string $name, ?string $schemaName = null, ?string $connection = null): Table Returns representation of a table, an Hector\Schema\Table object

It's an iterable class, returns Hector\Schema\Schema objects.

Hector\Schema\Schema

Represent a schema. Methods available:

• Schema::getName(bool $quoted = false): string Returns the name of schema
• Schema::getCharset(): string Returns the charset of schema
• Schema::getCollation(): string Returns the charset of schema
• Schema::getTables(): Generator Returns a generator of Hector\Schema\Table objects
• Schema::hasTable(string $name): bool Check if schema has a table
• Schema::getTable(string $name): Table Returns representation of a table, an Hector\Schema\Table object
• Schema::getContainer(): ?SchemaContainer Returns the container of schema if it's a part of a container

It's an iterable class, returns Hector\Schema\Table objects.
