PHP Reflection (Reflection) Use instance _php tips

The

PHP reflection is used to get details about the classes, extensions, methods, functions, objects, parameters, and properties. The
Reflectionclass class obtains class-related information, such as getting properties, methods, document comments, and so on.

<?php class Person {/** * For the sake of demonstration, we ' re setting this private * * Private $_allowdyn
 
  Amicattributes = false;
 
  /** type=primary_autoincrement * * protected $id = 0;
 
  /** Type=varchar length=255 NULL * * * protected $name;
 
  /** type=text NULL */protected $biography;
  Public Function GetId () {return $this->id;
  The Public Function setId ($v) {$this->id = $v;
  The Public Function GetName () {return $this->name;
  The Public Function SetName ($v) {$this->name = $v;
  The Public Function getbiography () {return $this->biography;
  The Public Function setbiography ($v) {$this->biography = $v;
 
}///Export class Reflectionclass::export (' person ');
 
$r = new Reflectionclass (' person ');
 
Gets all Properties Print_r ($r->getproperties ()); /** * Get the specified property * reflectionproperty::is_static * reflectionproperty::is_public * reflectionproperty::is_protected * REF Lectionproperty::is_private * * PRINT_R ($r->getproperties (reflectionproperty::is_private));
 
Gets the annotation print_r ($r->getproperty (' id ')->getdoccomment ());
 Get method Print_r ($r->getmethods ());

The Reflectionextension class is used to obtain extension-related information

$re = new Reflectionextension (' Reflection ');
Print_r ($re->getclasses ()); Extended All Class
Print_r ($re->getclassnames ());//Extend all class names
 
$dom = new Reflectionextension (' MySQL ');
Print_r ($dom->getconstants ())//Extended constant
Print_r ($dom->getdependencies ());//This extension relies on
Print_r ($dom-> Getfunctions ())//extension method
Print_r ($dom->getinientries ());//Extended INI Information
print_r ($dom->getname ());//Extended Name
Print_r ($dom->getversion ())//Extended version
Print_r ($dom->info ())//Extended information
print_r ($dom-> Ispersistent ());/Whether it is a persistent extension
Print_r ($dom->istemporary ());//Whether it is a temporary extension

Reflectionfunction class User Gets the information about the function

$RF = new Reflectionfunction (' Array_merge ');
 
foreach ($rf->getparameters () as $item) {
  echo $item. Php_eol;
}

Reflectionmethod-Class user access methods related information

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 class is used to get information about objects

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 gets information about a function or method parameter.

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 ($p->getposition ()); 0
Print_r ($p->getname ());//v

Reflectionproperty gets information about the properties of the class.

Class Person {
 
  /** Test
  /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 ());
