Object transformation Array and array transformation object instance in PHP

Convert an array to an object with Stdclass

PHP code

The code is as follows	Copy Code
$arr = Array (); $arr [' a '] = 1; $arr [' b '] = 2; $arr [' c '] = 3; $arr = Array (); $arr [' a '] = 1; $arr [' b '] = 2; $arr [' c '] = 3;

After converting with Stdclass:

PHP code

The code is as follows	Copy Code
$object = new StdClass; $object->a = 1; $object->b = 2; $object->c = 3; $object = new StdClass; $object->a = 1; $object->b = 2; $object->c = 3;

Stdclass is a base class for PHP, and almost all classes inherit this class, so any time you can be new, you can make this variable an object. At the same time, this base class has a special place, there is no way

The place I'm applying is the simplexml_load_string () in SimpleXML, because all the objects are returned, and if the data is more cumbersome to extract, the following function is applied

The code is as follows	Copy Code
function Object_to_array ($obj) { $_arr = Is_object ($obj)? Get_object_vars ($obj): $obj; foreach ($_arr as $key => $val) { $val = (Is_array ($val) | | | is_object ($val))? Object_to_array ($val): $val; $arr [$key] = $val; } return $arr; }

Array into an object

The code is as follows	Copy Code
<?php $array = Array (1 => php, 2 => Java, 3 => C); $arrayobject = new Arrayobject ($array); Var_dump ($arrayobject); ?>

Run Result:

The code is as follows	Copy Code
Object (Arrayobject) #1 (1) {[Storage]: "Arrayobject":p rivate]=> Array (3) {[1]=> string (3) "PHP" [2]=> string (4 ) "Java" [3]=> string (3) "C"}}

A class: Arrayobject, you can directly convert an array to an object

PHP code

The code is as follows	Copy Code
$array = Array (' 1 ' => ' one ', ' 2 ' => ' two ', ' 3 ' => ' three '); $arrayobject = new Arrayobject ($array); Var_dump ($arrayobject); $array = Array (' 1 ' => ' one ', ' 2 ' => ' two ', ' 3 ' => ' three '); $arrayobject = new Arrayobject ($array); Var_dump ($arrayobject);

Results:

The code is as follows	Copy Code
PHP code Object (Arrayobject) #1 (3) { [1]=> String (3) "One" [2]=> String (3) "Two" [3]=> String (5) "three" }
