Syntax

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";
}
