PHP Reflection是用于獲取類、擴展、方法、函數、對象、參數、屬性的詳細信息。 ReflectionClass類獲取類相關信息，如獲取屬性、方法、文檔注釋等。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 = $v;//導出類ReflectionClass::export('Person');$r = new ReflectionClass('Person');//獲取所有屬性print_r($r- getProperties()); * 獲取指定屬性 * ReflectionProperty::IS_STATIC * ReflectionProperty::IS_PUBLIC * ReflectionProperty::IS_PROTECTED * ReflectionProperty::IS_PRIVATEprint_r($r- getProperties(ReflectionProperty::IS_PRIVATE));//獲取注釋print_r($r- getProperty('id')- getDocComment());//獲取方法print_r($r- getMethods());ReflectionExtension 類用于獲取擴展相關信息$re = new ReflectionExtension('Reflection');print_r($re- getClasses()); //擴展的所有類print_r($re- getClassNames()); //擴展所有類名$dom = new ReflectionExtension('mysql');print_r($dom- getConstants());//擴展常量print_r($dom- getDependencies());//該擴展依賴print_r($dom- getFunctions());//擴展方法print_r($dom- getINIEntries());//擴展ini信息print_r($dom- getName());//擴展名稱print_r($dom- getVersion());//擴展版本print_r($dom- info());//擴展信息print_r($dom- isPersistent());//是否是持久擴展print_r($dom- isTemporary()); //是否是臨時擴展ReflectionFunction類 用戶獲取函數相關信息$rf = new ReflectionFunction('array_merge');foreach($rf- getParameters() as $item) { echo $item . PHP_EOL;}ReflectionMethod類用戶獲取方法相關信息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 類 用于獲取對象相關信息 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 獲取函數或方法參數的相關信息。 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 獲取類的屬性的相關信息。 class Person { /** 測試 */ 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
