To convert an object to an array method: Extend the Array_map function to invoke an internal method in a PHP class

 Public Static functionObjecttoarray ($d) {        if(Is_object($d)) {            $d=Get_object_vars($d); }        if(Is_array($d)) {            return Array_map(Array(__class__,__function__),$d); } Else {            return $d; }    }

Array_map (Array ($d) explains:

We can find a user-added description in the PHP manual:

If you need to call a static method from array_map, this will NOT work:
（如果你想在array_map函数中回调一个静态方法，那么下面的做法是错误的）

 <? PHP   $a  = array  (1, 2, 3, 4, 5);  $b  = array_map  ("Myclass::mymethoed", Span style= "color: #800080;" > $a   print_r  ( $b  ? >  

 < Span style= "color: #ff00ff;" >   
 Instead, you need to does this: 
 (you should make the following call) 
 
    

<? PHP $a Array (1, 2, 3, 4, 5); $b Array_map (array$a); Print_r ($b);

Thanks to the author for sharing, because the parameter descriptions of the Array_map function in the PHP manual are really too simple to mention even the basic object method references.

Now let's go to the topic we're talking about: what do you do if you call the internal method through the Array_map function in a PHP class?

First look at the code (PS: Due to the length of the article, I had to remove the comments ...) ）：

public static function_entities($arg){

This would neithor work under static call nor class instantiate
$return = Array_map (Array (self, ' _entities '), $arg);

This would work under both static Call and class instantiate
$return=Array_map(Array (__class__,' _entities '),$arg);
}else{
$return=Is_numeric($arg) ?$arg:Htmlspecialchars($arg,Ent_quotes);
}
Return$return;

Here are a few things you can refer to:

1, the class name can be used when the internal method is recalled through the Array_map function in the PHP class__class__Constant.We strongly recommend that you use this constant, because no matter how you modify the class, this will ensure that the final result is correct. 

2, if the callback method is non-static type, you can also pass$thisA pseudo-variable is specified.

3, the Array_map function in the PHP class is not always recognized SelfPseudo variables.
