DbReflection
Reflection classes for databases. [Has only been tested against MySQL], (*2)
Install
You can install it by downloading the zip and including it in your project or, preferably, using Composer., (*3)
{
"require": {
"belsrc/db-reflection": "dev-master"
}
}
If you are using Laravel you can also include the ServiceProvider in the app/config/app.php 'providers' array., (*4)
'Belsrc\DbReflection\DbReflectionServiceProvider'
as well as the Facade in the 'aliases' array., (*5)
'DbReflection' => 'Belsrc\DbReflection\Facades\DbReflection'
Quick Example
$col = DbReflection::getColumn( 'column', 'table', 'database' );
You can also use the short-hand, cleaner route., (*6)
$col = DbReflection::getColumn( 'database.table.column' );
Commands
If using Laravel, the package will also expose a few artisan command., (*7)
reflect:column path Get the information about a particular column.
Argument: path The 'path' of the column (i.e. 'database.table.column')
reflect:database database Get the information about a particular database.
Argument: database The name of the database.
reflect:table path Get the information about a particular table.
Argument: path The 'path' of the table (i.e. 'database.table.column')
