对于包含私有属性的类,property_exists()函数返回true(php> 5.3)。对于函数,有一个is_callable方法,它不仅确认方法存在,而且还可用(作为method_exists()的替代方法)。是否有与此函数等效的对应函数来确认此属性是否可访问?
<?php
class testClass {
private $locked;
public $unlocked;
private function hiddenFunction(){
return "hidden";
}
public function visibleFunction(){
return "visible";
}
}
$object = new testClass();
var_dump(property_exists($object, "unlocked")); // returns true
var_dump(property_exists($object, "locked")); // returns true > php 5.3
var_dump(method_exists($object, "hiddenFunction")); // returns true but can't be called
var_dump(method_exists($object, "visibleFunction")); // returns true
var_dump(is_callable(array($object, "hiddenFunction"))); // returns false
var_dump(is_callable(array($object, "visibleFunction"))); // returns true
?>

您可以使用Reflection类taht让您逆向工程类,接口,函数,方法和扩展。
例如,要获取类的所有公共属性,可以执行以下操作:
$reflectionObject = new ReflectionObject($object);
$testClassProperties = $reflectionObject->getProperties(ReflectionProperty::IS_PUBLIC);
print_r ($testClassProperties);
<强>输出强>
Array
(
[0] => ReflectionProperty Object
(
[name] => unlocked
[class] => testClass
)
)
获取类的所有公共方法,您可以执行以下操作:
$reflectionObject = new ReflectionObject($object);
$testClassProperties = $reflectionObject->getMethods(ReflectionProperty::IS_PUBLIC);
print_r ($testClassProperties);
<强>输出强>
Array
(
[0] => ReflectionMethod Object
(
[name] => visibleFunction
[class] => testClass
)
)
