Getting variable names of class

PHP
1

I need to get variable names…
For example:


<?php

class forex{
  public $example;
  public $example2;
  public $example3;

  function getNames()
  {
     return variableNames();
  }
}

$class = new forex();
$class->getNames();
?>

I want to get a (like)array like:


array('example','example2','example3');

I wish I tell you.

Ok thank you so much. I have find more useful usage, but I don’t know, maybe it have a problem?


<?php
class Datas {

    public $one;
    public $two;
    public $three;
   
    public function _GetName()
    {
       return $this;
    }
}

$data = new Datas();
print_r($data->_GetName());
?>

Result:

Datas Object ( [one] => [two] => [three] => )

It usage is good or have problems?

…Sure you could do that…but if that is all you wanted

$data = new Datas;
print_r( $data );

No need for the method.

No, your codes have problem. You need to convert your object to array. It need to be below:


$data = new Datas;
$array = (array) $data;
print_r($array);

No, my code does not have a problem.
My code returns the same thing your code above returns.

print_r can’t show object data.

Sorry, but you are mistaken. Do not try and school me in PHP, I’ve been working with it professionally for years. print_r can show object data. Read the documentation: http://www.php.net/manual/en/function.print-r.php

If given a string, integer or float, the value itself will be printed. If given an array, values will be presented in a format that shows keys and elements. Similar notation is used for objects.

Ohh sorry really. I was want to say array_keys can’t use object data. Sorry.
