基于PHP的医院住院管理系统

基于PHP的医院住院管理系统是一个用于管理医院住院患者的信息系统。该系统可以帮助医院工作人员高效地处理患者信息，包括挂号、查询、缴费、出院等流程。以下是一个简单的PHP实现示例：

1. 首先，创建一个名为`hospital_system`的数据库表，用于存储患者信息：

```sql

CREATE TABLE `hospital_system` (

`id` int(11) NOT NULL AUTO_INCREMENT,

`patient_name` varchar(255) NOT NULL,

`patient_age` int(11) NOT NULL,

`patient_gender` varchar(10) NOT NULL,

`patient_phone` varchar(20) NOT NULL,

`hospital_id` int(11) NOT NULL,

PRIMARY KEY (`id`),

FOREIGN KEY (`hospital_id`) REFERENCES `hospital_system` (`hospital_id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

```

2. 创建一个名为`hospital_system_controller`的控制器类，用于处理HTTP请求：

```php

class HospitalSystemController extends PhalconMvcDispatchHttpPhpController

{

public function indexAction()

{

$this->viewRenderer()->setVariable('patients', $this->getPatients());

}

public function addAction()

{

$patient = new Patient();

if ($patient->save()) {

$this->flashMessenger()->addSuccessMessage('患者信息添加成功');

} else {

$this->flashMessenger()->addErrorMessage('患者信息添加失败');

}

$this->redirect('/hospital_system/index');

}

public function deleteAction($patient_id)

{

$patient = $this->getPatientById($patient_id);

if ($patient) {

$patient->delete();

$this->flashMessenger()->addSuccessMessage('患者信息删除成功');

} else {

$this->flashMessenger()->addErrorMessage('患者信息未找到');

}

$this->redirect('/hospital_system/index');

}

}

```

3. 创建一个名为`patient`的模型类，用于处理数据操作：

```php

class Patient extends PhalconMvcModelAbstractModel

{

public function initialize()

{

$this->__initialize('database.patients', 'patient_id');

}

public function getPatients()

{

$query = $this->find();

return $query->toArray();

}

public function save()

{

$data = $this->getInput();

$data['patient_name'] = $data['patient_name'] ?? '';

$data['patient_age'] = $data['patient_age'] ?? '';

$data['patient_gender'] = $data['patient_gender'] ?? '';

$data['patient_phone'] = $data['patient_phone'] ?? '';

$this->save($data);

}

public function delete()

{

$patient_id = $this->getParam('patient_id');

$this->delete($patient_id);

$this->flashMessenger()->addSuccessMessage('患者信息删除成功');

}

}

```

4. 创建一个名为`patient_form`的表单类，用于处理表单提交：

```php

class PatientForm extends PhalconFormForm

{

public function initialize()

{

$this->setName('patient');

$this->setMethod('post');

$this->setValidator([

'patient_name' => [new PhalconValidationValidatorStringLengthValidator(1, 255)],

'patient_age' => [new PhalconValidationValidatorNumberValidator(1, 120)],

'patient_gender' => [new PhalconValidationValidatorStringLengthValidator(1, 10)],

'patient_phone' => [new PhalconValidationValidatorEmailValidator]

]);

}

}

```

5. 创建一个名为`patient_validator`的验证器类，用于验证表单数据：

```php

class PatientValidator

{

public function validate($data)

{

foreach ($data as $key => $value) {

if (!$this->isValid($value)) {

$this->errors[$key] = '数据无效';

}

}

return $this->errors;

}

private function isValid($value)

{

switch ($value) {

case '':

return false;

default:

return true;

}

}

}

```

6. 创建一个名为`patient_route`的路由类，用于处理HTTP请求：

```php

use PhalconMvcRouteAnnotationPrefix;

use PhalconMvcRouteAnnotationHttpMethod;

use PhalconMvcRouteAnnotationRequirement;

use PhalconMvcView;

use PhalconMvcViewEnginePhpEngine;

use PhalconMvcViewEngineTemplateEngine;
