PHP Reflection是用于获取类、扩展、方法、函数、对象、参数、属性的详细信息。 ReflectionClass类获取类相关信息，如获取属性、方法、文档注释等。html' target='_blank'>class Person { * For the sake of demonstration, we"re setting this private private $_allowDynamicAttributes = false; /** type=primary_autoincrement */ protected $id = 0; /** type=varchar length=255 null */ protected $name; /** type=text null */ protected $biography; public function getId() return $this- public function setId($v) $this- id = $v; public function getName() return $this- name; public function setName($v) $this- name = $v; public function getBiography() return $this- biography; public function setBiography($v) $this- biography = $v;//导出类ReflectionClass::export('Person');$r = new ReflectionClass('Person');//获取所有属性print_r($r- getProperties()); * 获取指定属性 * ReflectionProperty::IS_STATIC * ReflectionProperty::IS_PUBLIC * ReflectionProperty::IS_PROTECTED * ReflectionProperty::IS_PRIVATEprint_r($r- getProperties(ReflectionProperty::IS_PRIVATE));//获取注释print_r($r- getProperty('id')- getDocComment());//获取方法print_r($r- getMethods());ReflectionExtension 类用于获取扩展相关信息$re = new ReflectionExtension('Reflection');print_r($re- getClasses()); //扩展的所有类print_r($re- getClassNames()); //扩展所有类名$dom = new ReflectionExtension('mysql');print_r($dom- getConstants());//扩展常量print_r($dom- getDependencies());//该扩展依赖print_r($dom- getFunctions());//扩展方法print_r($dom- getINIEntries());//扩展ini信息print_r($dom- getName());//扩展名称print_r($dom- getVersion());//扩展版本print_r($dom- info());//扩展信息print_r($dom- isPersistent());//是否是持久扩展print_r($dom- isTemporary()); //是否是临时扩展ReflectionFunction类 用户获取函数相关信息$rf = new ReflectionFunction('array_merge');foreach($rf- getParameters() as $item) { echo $item . PHP_EOL;}ReflectionMethod类用户获取方法相关信息class Person { public $name; * get name of person public function getName() return $this- name; public function setName($v) $this- name = $v;$rm = new ReflectionMethod('Person', 'getName');print_r($rm- isPublic());print_r($rm- getDocComment());ReflectionObject 类 用于获取对象相关信息 class Person { public $name; public function __construct($name) $this- name = $name; public function getName() return $this- name; public function setName($v) $this- name = $v;$a = new Person('a');$ro = new ReflectionObject($a);print_r($ro- getMethods());ReflectionParameter 获取函数或方法参数的相关信息。 class Person { public $name; public function __construct($name) $this- name = $name; public function getName() return $this- name; public function setName($v) $this- name = $v;$p = new ReflectionParameter(array('Person', 'setName'), 0);print_r($p- getPosition()); //0print_r($p- getName()); //vReflectionProperty 获取类的属性的相关信息。 class Person { /** 测试 */ public $name; public function __construct($name) $this- name = $name; public function getName() return $this- name; public function setName($v) $this- name = $v;$p = new ReflectionProperty('Person', 'name');print_r($p- getDocComment());PHP教程
