PHP Reflection Reflectionclass,phpreflectionclass


Today, we have a problem with the following code:

classa.php

 
  

  

classb.php

 
  ';p rint_r ($classFuncB);? >

When I need to find out all the methods in CLASSB, the result is as follows:

Array (    [0] = FUNCBA    [1] = FUNCBB    [2] = FUNCBC    [3] = = FUNCAA    [4] = = Funcab    [5] = > FUNCAC)

Altogether 6 methods, actually I do not want to inherit the ClassA inside the method, I only want ClassB method, how to do? I changed a little bit as follows:

$classA = new ClassA; $classB = new ClassB; $classFuncA = Get_class_methods ($classA); $classFuncB = Get_class_methods ($ ClassB); Echo '
';p Rint_r (Array_diff ($classFuncB, $classFuncA));

The results are as follows:

Array (    [0] = FUNCBA    [1] = FUNCBB    [2] = FUNCBC)

One less method FUNCAA, although FUNCAA is ClassB inherit from ClassA, but same ClassB also have this method, so not I want the result.

Workaround:

$reflection = new Reflectionclass (' ClassB ');p rint_r ($reflection->getmethods ());

Results:

Array (    [0] = = Reflectionmethod Object        (            [name] = FUNCBA            [Class] = ClassB        )    [1] = > Reflectionmethod Object        (            [name] = FUNCBB            [Class] = ClassB        )    [2] = = Reflectionmethod Object        (            [name] = FUNCBC            [Class] = ClassB        )    [3] = = Reflectionmethod Object        (            [name] = FUNCAA            [Class] = ClassB        )    [4] = = Reflectionmethod Object        (            [name] = Funcab            [Class] = ClassA        )    [5] = = Reflectionmethod Object        (            [name] = FUNCAC            [Class] = ClassA        ))

You can see that the value of class corresponding to [4], [5] is ClassA, and the other corresponding values are CLASSB. With this you can use foreach to achieve the final desired result:

$reflection = new Reflectionclass (' ClassB '); $array = "; foreach ($reflection->getmethods () as $obj) {if ($obj, class = = $reflection->getname ()) {//$reflection->getname () Gets the class name $array[] = $obj->name;}} Echo '
';p rint_r ($array);

Final Result:

Array (    [0] = FUNCBA    [1] = FUNCBB    [2] = = FUNCBC    [3] = = FUNCAA)

How PHP converts objects that reflect initialization to objects of a class

You have to be sure that the class definition file of the user class is introduced, otherwise deserialization will not succeed.
If the deserialization fails, the $user will not be an instance of the user object, and there will be no method getmodelname.
