Changelog:
5.0.3
get_class_vars()
5.0.2
Calling get_class_vars() will now expose all the properties as an array, unlike previous behaviour where protected and private properties were prefixed with nul bytes.
5.0.1
Calling get_class_vars() will expose all properties, as when converting an object to a class.
Examples:
get_class_vars() example
<?php class myclass { var $var1; // this has no default value... var $var2 = "xyz"; var $var3 = 100; private $var4; // 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 : $value\n"; } ?>
The above example will output:
var1 : var2 : xyz var3 : 100
get_class_vars() and scoping behaviour
<?php function format($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
