ReflectionClass::getProperties

(PHP 5)

ReflectionClass::getProperties — Gets properties

说明

public array ReflectionClass::getProperties ([ int $filter ] )

Retrieves reflected properties.

参数

filter

The optional filter, for filtering desired property types. It's configured using the ReflectionProperty constants, and defaults to all property types.

返回值

An array of ReflectionProperty objects.

范例

Example #1 ReflectionClass::getProperties() filtering example

This example demonstrates usage of the optional filter parameter, where it essentially skips private properties.

<?php
class Foo {
    public    $foo  = 1;
    protected $bar  = 2;
    private   $baz  = 3;
}

$foo = new Foo();

$reflect = new ReflectionClass($foo);
$props   = $reflect->getProperties(ReflectionProperty::IS_PUBLIC | ReflectionProperty::IS_PROTECTED);

foreach ($props as $prop) {
    print $prop->getName() . "\n";
}

var_dump($props);

?>

以上例程的输出类似于：

foo
bar
array(2) {
  [0]=>
  object(ReflectionProperty)#3 (2) {
    ["name"]=>
    string(3) "foo"
    ["class"]=>
    string(3) "Foo"
  }
  [1]=>
  object(ReflectionProperty)#4 (2) {
    ["name"]=>
    string(3) "bar"
    ["class"]=>
    string(3) "Foo"
  }
}
