bimini-php

Easily check and retrieve BIMI records from a host

Basic usage

First require biohzrdmx/bimini-php with Composer.

Then create a Bimini instance; for that you must pass an StorageInterface implementation and this package includes a simple file system storage adapter named FileSystemStorage:

$path = dirname(__FILE__) . DIRECTORY_SEPARATOR . 'output';
$storage = new FileSystemStorage($path);
$bimini = new Bimi($storage);

The FileSystemStorage implementation uses a local directory to store the result of the DNS record queries, to minimize network requests; you may also write your own storage adapters for database, Redis, Memcached or any other persistance mechanism, just implement the StorageInterface methods.

Now that you have a Bimini instance you can query any host, for example you can check for the existence of a record with the hasRecord method:

$ret = $bimini->hasRecord('example.com');

Or retrieve the complete record with the getRecord method:

$record = $bimini->getRecord('example.com');

Once you have the record you can check its properties with the has- methods (hasVersion, hasLogo, hasCertificate) or retrieve the actual properties with the get- methods (getVersion, getLogo, getCertificate), for example:

if ( $record->hasLogo() ) {
    $url = $record->getLogo();
}

Actually there is only one BIMI version, so the getVersion method should always return BIMI1 for a valid record.

Both getLogo and getCertificate methods return a URL to the respective resource (the SVG image or the PEM file). The library does not validate these URLs, it only returns the value stored in the BIMI record; it's up to you if you want to render the SVG file or check the VMC certificate.
