PHP générateur de classe d'entité
Je crée des classes d'entité (de entity-view-controller) (en d'autres termes, un modèle de MVC) qui correspondent théoriquement à la table de base de données que j'ai. Existe-t-il un outil qui lit la table mysql et crée un code de classe de modèle? (PAS lors de l'exécution, une sortie de code est requise) J'attends une sortie comme
class{
public $columnname1;
public $columnname2;
public $columnname3;
public $columnname4;
public $columnname5;
public $columnname6;
function __construct(&$columnname1, &$columnname2){...}
function insert(&$columnname1, &$columnname2){}
function delete(&$columnname1){}
...
}
Un outil qui créerait également des fonctions d'insertion, de mise à jour et de suppression par identifiant m'aiderait beaucoup.
L'outil peut être gratuit ou payant.
PDO peut extraire les résultats dans un objet.
Concevez une classe qui correspond à votre structure de base de données/requête et utilisez PDO::FETCH_INTO pour extraire le jeu de résultats dans un objet déjà instancié. </ S> Ne lisez pas la question, mon mauvais.
Pour générer la classe elle-même à partir de la structure de la base de données, il existe plusieurs projets (je n'ai pas encore testé, mais cela s'est fait sur une recherche très simple).
Le code suivant correspond à ce que j'ai utilisé pendant longtemps pour créer des modèles PHP pour les tables MySQL et DB2. J'ai des fiches en place pour MSSQL, PGSQL et SQLite mais je n'ai jamais eu besoin de les compléter.
Voici la classe du générateur de code:

Je comprends que vous cherchiez un genre de chose ORM.
j'espère que cela t'aides
Qu'en est-il symfony ? Il fait exactement ce que vous dites et vous obtenez un très bon cadre qui va avec.
symfony "compile" les classes pour vous en fonction d'un modèle de données que vous fournissez. Il s'assurera que les classes compilées et la structure de la base de données MySQL sont synchronisées.
Cette approche est favorable par rapport à une approche basée sur Reflection car elle est tout simplement trop lente.
Pour ce que ça vaut, Rafael Rocha share code here .
Cependant, j’ai fortement propose d’utiliser un ORM Transformer la structure MySQL en couche de base de données est tout sauf bon ...
Essayez ceci https://github.com/rcarvello/mysqlreflection
Un utilitaire utile que j'ai construit pour le mappage de relation d'objet des bases de données MySQL.
L'utilitaire génère automatiquement des classes PHP pour toutes les tables d'un schéma de base de données donné.
Le paquet est extrait de mon framework personnel PHP Web MVC.
J'ai écrit un code PHP qui détectera automatiquement toutes les bases de données de la base de données MYSQL. Lors de la sélection de l'une des bases de données, toutes les tables associées sont chargées. Vous pouvez sélectionner toutes les tables ou n'importe quelle table respective pour générer la classe modale.
Ce qui suit est le lien vers mon référentiel
https://github.com/channaveer/EntityGenerator
Cela créera automatiquement un dossier Entity et affichera toute la classe d'entités dans ce dossier.
NOTE - Actuellement uniquement supporté pour MYSQL
J'espère que ça aide. Bon codage!
Oui, la doctrine est ce dont vous avez besoin.
Exécutez une commande et obtenez les métadonnées de toutes vos tables au format XML ou YML (à vous de choisir)
$ php app/console doctrine: mapping: convertir xml ./src/Bundle/Resources/config/doctrine/metadata/orm --from-database --force
Une fois que vous avez généré les métadonnées, command Doctrine permet d’importer le schéma afin de créer les classes d’entités associées dont vous avez besoin. Vous trouverez toutes les fonctionnalités GET et SET (lire S&EACUTE;LECTIONNER, METTRE &AGRAVE; JOUR et INS&EACUTE;RER) à l'intérieur.
1. $ php app/console doctrine: mapping: importation de l'annotation Bundle
2. $ php app/console doctrine: générer: entités Bundle
Fat free framework vous permet de travailler avec des tables existantes en utilisant un code tel que:
$user=new DB\SQL\Mapper($db,'users');
// or $user=new DB\Mongo\Mapper($db,'users');
// or $user=new DB\Jig\Mapper($db,'users');
$user->userID='jane';
$user->password=md5('secret');
$user->visits=0;
$user->save();
Le code ci-dessus crée un nouvel enregistrement dans la table users
