Php 如何获取实体属性的类型

实际上，我有一个条令实体，我需要动态地填充它的属性

我希望能够做到这样：

$entity = new Entity();
$reflect = new ReflectionClass($entity);
// $fields is an array whihch contain the entity name as the array key and the value as the array value
foreach ($fields as $key => $val)
{
    if (!reflect->hasProperty($key)) {
        var_dump('the entity does not have a such property');
        continue;
    }
    if ( the type of $key is string ) {
          // convert $value to utf8
    } elseif ( the type of $key is integer) {
          // do something else
    } //....etc
}

我该怎么做？

您可以使用

找到了。我希望这会有帮助

use Doctrine\Common\Annotations\AnnotationReader;

$docReader = new AnnotationReader();
$entity = new Entity();
$reflect = new ReflectionClass($entity);
// $fields is an array whihch contain the entity name as the array key and the value as the array value
foreach ($fields as $key => $val)
{
    if (!reflect->hasProperty($key)) {
        var_dump('the entity does not have a such property');
        continue;
    }
    $docInfos = $docReader->getPropertyAnnotations($reflect->getProperty($key));
    if ( $docInfos[0]->type === 'string' ) {
          // convert $value to utf8
    } elseif ( $docInfos[0]->type === 'integer' ) {
          // do something else
    } //....etc
}

尽管这篇文章很古老，但当我们需要解决布尔字段在某些上下文中总是设置为true的问题时，它确实很有用——谢谢smarber和yoshi。我们的解决方案检测布尔字段（在本例中为PATCH），并使用相应的setter来传播值。（当然，如果没有必要，那就太好了。）

参考：

如果您对实体字段的注释很少，则以任何顺序显示。
注意：此代码不用于检测相关实体（多通、一通等）

你可以简单地使用。它可能会提供您需要的有关实体的所有信息。与getProperty（$key）->getDocComment完全相同，不会提供更好的信息。我想唯一的方法是获取属性注释/注释并解析它（gotcha:），不过我花了一段时间。Thx这将不起作用，因为我的实体属性没有设置为初始值所以很有用！这两个答案都有效，但我喜欢这个，因为它很简单。你的意思是键是字段名而不是实体名吗？

use Doctrine\Common\Annotations\AnnotationReader;

$docReader = new AnnotationReader();
$entity = new Entity();
$reflect = new ReflectionClass($entity);
// $fields is an array whihch contain the entity name as the array key and the value as the array value
foreach ($fields as $key => $val)
{
    if (!reflect->hasProperty($key)) {
        var_dump('the entity does not have a such property');
        continue;
    }
    $docInfos = $docReader->getPropertyAnnotations($reflect->getProperty($key));
    if ( $docInfos[0]->type === 'string' ) {
          // convert $value to utf8
    } elseif ( $docInfos[0]->type === 'integer' ) {
          // do something else
    } //....etc
}

/*
 * @PATCH("/entity/{name}")
 */
public function patchEntityAction(Request $request, $entity)
{
    ...

    $form->handleRequest($request);

    $manager = $this->getDoctrine()->getManager();

    // handle booleans
    $metadata      = $manager->getClassMetadata($bundle_entity);
    $entity_fields = $metadata->getFieldNames();
    foreach ($entity_fields as $field) {
        $type = $metadata->getTypeOfField($field);
        if ($request->request->has("$field") && $type == 'boolean') {
            $setter = 'set' . ucfirst($field);
            $entity->$setter(!!$request->request->get("$field"));
        }
    }

    $manager->persist($entity);
    $manager->flush();

    ...

}

use Doctrine\Common\Annotations\AnnotationReader;

/**
 * @param $entity
 * @param $fieldName
 * @return mixed|null
 */
private function getFieldType($entity, $fieldName)
{
    $annotationReader = new AnnotationReader();
    $refClass = new ReflectionClass($entity);
    $annotations = $annotationReader->getPropertyAnnotations($refClass->getProperty($fieldName));

    if (count($annotations) > 0) {
        foreach ($annotations as $annotation) {
            if (
                $annotation instanceof \Doctrine\ORM\Mapping\Column
                && property_exists($annotation, 'type')
            ) {
                return $annotation->type;
            }
        }
    }

    return null;
