+# urfat-orm
+
+A lightweight, zero-dependency PHP ORM with Laravel/Eloquent-inspired syntax. Built on top of PDO, it supports multiple named connections, soft deletes, timestamps, eager loading, and pivot table relationships.
+
+---
+
+## Installation
+
+```bash
+composer install
+```
+
+No external dependencies. PHP 8.0+ required.
+
+---
+
+## Setup
+
+```php
+require 'vendor/autoload.php';
+
+use ORM\Connection;
+use ORM\Connections;
+
+// Using the factory helper
+$pdo = Connection::open('pgsql', 'dbname=mydb host=localhost', 'user', 'pass', 'myprefix_');
+
+// Or register a raw PDO
+$pdo = new PDO("pgsql:dbname=mydb;host=localhost", 'user', 'pass');
+$pdo->prefix = 'myprefix_';
+Connections::addConnection($pdo);              // 'default'
+Connections::addConnection($pdo, 'secondary'); // named connection
+```
+
+Supported drivers: `pgsql`, `mysql`, `sqlite`, `firebird`, `oracle`, `mssql`.
+
+---
+
+## Defining a Model
+
+```php
+use ORM\Entity;
+
+class User extends Entity {
+    const _tableName      = 'users';
+    const _connectionName = 'default';    // optional, defaults to 'default'
+    const _softdelete     = true;         // filters deleted_at IS NULL on all queries
+    const _timestamps     = true;         // auto-sets created_at / updated_at on save
+    const _ignore         = ['password_confirm']; // excluded from INSERT / UPDATE
+    const _idPolice       = [             // optional custom ID strategy
+        'type' => 'nextval',
+        'min'  => 500,
+        'max'  => 9999,
+        'step' => 10,
+    ];
+
+    protected function posts() {
+        return $this->hasMany(Post::class, 'user_id');
+    }
+
+    protected function country() {
+        return $this->belongsTo(Country::class, 'country_id', 'id');
+    }
+
+    protected function roles() {
+        return $this->belongsToMany(Role::class, 'role_user', 'user_id', 'role_id');
+    }
+}
+```
+
+---
+
+## Features
+
+### CRUD
+
+```php
+// Create
+$user = new User(['name' => 'Alice', 'email' => 'alice@example.com']);
+$user->save(); // INSERT; $user->id is populated after
+
+// Read
+$user  = User::findOne(42);
+$user  = User::findOne(['email' => ['=', 'alice@example.com']]);
+$users = User::findAll();
+$users = User::findMany(['active' => ['=', 1]], ['*'], ['LIMIT' => 10, 'OFFSET' => 0]);
+$n     = User::count(['active' => ['=', 1]]);
+
+// Update
+$user->name = 'Bob';
+$user->save(); // UPDATE because $user->id exists
+
+// Delete
+$user->delete(); // soft-delete if _softdelete=true, otherwise hard-delete
+$user->purge();  // always hard-delete
+$user->restore(); // clears deleted_at (soft-delete models only)
+```
+
+Criteria format: `['column' => ['operator', value]]`
+Supported operators: `=`, `<`, `>`, `<=`, `>=`, `IN`, `LIKE`
+
+### Soft Delete
+
+When `_softdelete = true`, all `findAll`, `findOne`, `findMany`, and `count` calls automatically append `WHERE deleted_at IS NULL`. Pass `true` as the last argument to include trashed records:
+
+```php
+$all     = User::findAll(['*'], [], true);   // includes soft-deleted
+$trashed = User::findOne(42, ['*'], true);
+```
+
+### Timestamps
+
+When `_timestamps = true`, `created_at` and `updated_at` are set on construction and `updated_at` is refreshed on every `save()`.
+
+### Relationships
+
+| Method | Description |
+|---|---|
+| `hasOne(Class, $remoteField)` | One child record keyed by local id |
+| `hasMany(Class, $remoteField)` | Many child records keyed by local id |
+| `belongsTo(Class, $localField, $remoteField)` | Parent record |
+| `belongsToMany(Class, $pivot, $localKey, $remoteKey)` | Many-to-many via pivot |
+| `belongsToManyExtended(...)` | Many-to-many via pivot; returns pivot rows with foreign object in `->childElement` |
+
+```php
+// Lazy load (fires a query on access)
+$posts   = $user->posts()->get();
+$country = $user->country;   // magic __get shorthand
+
+// Eager load on a Collection
+$users = User::findAll()->with(['posts', 'country']);
+
+// Eager load on a single Entity
+$user->with(['posts', 'country']);
+```
+
+### Multiple Named Connections
+
+```php
+Connections::addConnection($pdo1);              // 'default'
+Connections::addConnection($pdo2, 'analytics'); // 'analytics'
+
+class Event extends Entity {
+    const _connectionName = 'analytics';
+}
+```
+
+### Custom ID Strategy (`_idPolice`)
+
+When `type = 'nextval'` the ORM computes the next ID from `MAX(id)` before inserting, respecting `min`, `max`, and `step`. Useful for databases without auto-increment sequences.
+
+### Raw Query Helpers (`DBInstance`)
+
+For queries that don't fit the Entity API:
+
+```php
+use ORM\DBInstance;
+
+// Single record with prepared statement
+$row  = DBInstance::getRecord('users', ['email' => ['=', $email]]);
+
+// Multiple records
+$rows = DBInstance::getRecords('users', ['active' => ['=', 1]], ['id', 'name'], ['LIMIT' => 50]);
+
+// Free SQL
+$rows = DBInstance::getRecordsSql("SELECT * FROM {users} WHERE created_at > ?", [$date]);
+
+// Insert and get last id
+$id = DBInstance::insertRecord('logs', ['action' => 'login', 'user_id' => 1]);
+
+// Update a single field
+DBInstance::setField('users', 'active', 0, $id);
+
+// Direct query
+DBInstance::execute("UPDATE {users} SET score = score + 1 WHERE id = ?", [$id]);
+```
+
+Table names always use `{tableName}` placeholder syntax so the connection prefix is applied automatically.
+
+### SQL Tracing
+
+```php
+$pdo->traceSQL = true; // prints every query to stdout
+```
+
+---
+
+## Known Bugs
+
+| # | Location | Description |
+|---|---|---|
+| 1 | `Collection::with()` | After the Relations namespace refactor, the `switch` class-name checks still use old names (`ORM\HasMany`, etc.) — all branches fall to `default`, which works but is inaccurate |
+| 2 | `Entity::findMany()`, `Entity::count()` | When no criteria are given and `_softdelete = true`, `AND deleted_at IS NULL` is appended without a preceding `WHERE`, producing invalid SQL |
+| 3 | `Entity` constructor / `update()` | Timestamp format uses `date('Y-m-d h:m:s')` — `h` is 12-hour clock and the second `m` is month; should be `date('Y-m-d H:i:s')` |
+| 4 | `Entity::__get()` | Returns `0` for any undefined property, silently masking typos |
+| 5 | `DBInstance::queryOne()` | When called with `$data`, it delegates to `queryPrepare()` which calls `fetchAll()` and returns an array, not a single object |
+| 6 | `DBInstance::setField()` | Uses PHP string interpolation `{$table}` instead of the ORM's `{tableName}` syntax, so the connection prefix is never applied |
+| 7 | `Entity::findMany()` | Values are interpolated directly into SQL (no prepared statements), making this method unsafe for user-supplied input |
+
+---
+
+## To Do
+
+- [ ] Fix `findMany()` and `count()` soft-delete `WHERE` clause when no other criteria exist
+- [ ] Fix timestamp format (`H:i:s`)
+- [ ] Fix `Collection::with()` class-name checks after Relations namespace refactor
+- [ ] Fix `DBInstance::setField()` table prefix placeholder
+- [ ] Fix `DBInstance::queryOne()` to actually return one record
+- [ ] Make `findMany()` use prepared statements
+- [ ] `Collection::with()` — use a bulk `IN (...)` query instead of one query per item (N+1 problem)
+- [ ] Relations cannot be iterated in Mustache / template engines (magic `__get` on `Entity` calls `->get()` but templates can't iterate the result transparently)
+- [ ] `__get()` should return `null` instead of `0` for undefined properties
+- [ ] Add formal test suite (PHPUnit)
+- [ ] Support `ORDER BY` in `findAll()` and `findMany()`
+- [ ] Support `whereNull` / `whereNotNull` criteria shorthand
