PHP: get_class_vars

Description

array get_class_vars ( string class_name )

This function will return an associative array of default public properties of the class. The resulting array elements are in the form of varname => value.

Note: Prior to PHP 4.2.0, Uninitialized class variables will not be reported by get_class_vars().

Example 1. get_class_vars() example

<?php class myclass { var $var1; // this has no default value... var $var2 = "xyz"; var $var3 = 100; private $var4; // PHP 5 // constructor function myclass() { // change some properties $this->var1 = "foo"; $this->var2 = "bar"; return true; } } $my_class = new myclass(); $class_vars = get_class_vars(get_class($my_class)); foreach ($class_vars as $name => $value) { echo "$name : $value\n"; } ?>
The above example will output:
// Before PHP 4.2.0 var2 : xyz var3 : 100 // As of PHP 4.2.0 var1 : var2 : xyz var3 : 100

in PHP5 to get all the vars (including private etc.) use:



$reflection = new ReflectionClass($class);

$defaults = $reflection->getdefaultProperties();

If you want to retrieve the class vars from within the class itself, use $this.



<?php

class Foo {



    var $a;

    var $b;

    var $c;

    var $d;

    var $e;



    function GetClassVars()

    {

        return array_keys(get_class_vars(get_class($this))); // $this

    }



}



$Foo = new Foo;



$class_vars = $Foo->GetClassVars();



foreach ($class_vars as $cvar)

{

    echo $cvar . "<br />\n";

}

?>



Produces, after PHP 4.2.0, the following:



a

b

c

d

e
