get_class_vars — Get the default properties of the class
get_class_vars(string $class): array
Get the default properties of the given class.
classThe class name
Returns an associative array of declared properties visible from the current scope, with their default value. The resulting array elements are in the form of varname => value. In case of an error, it returns false.
Example #1 get_class_vars() example
<?php
class MyClass
{
public $var1; // This has no explicit default value (technically it has NULL as a default)...
public $var2 = "xyz";
public $var3 = 100;
private $var4;
public function __construct()
{
// 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}: ", var_export($value, true), "\n";
}
?> The above example will output:
var1: NULL var2: 'xyz' var3: 100
Example #2 get_class_vars() and scoping behaviour
<?php
function format($array)
{
return implode('|', array_keys($array)) . "\r\n";
}
class TestCase
{
public $a = 1;
protected $b = 2;
private $c = 3;
public static function expose()
{
echo format(get_class_vars(__CLASS__));
}
}
TestCase::expose();
echo format(get_class_vars('TestCase'));
?> The above example will output:
// 5.0.0 a| * b| TestCase c a| * b| TestCase c // 5.0.1 - 5.0.2 a|b|c a|b|c // 5.0.3 + a|b|c a
