get_class_methods
There seems to be be a function to get constants missing , i.e. get_class_constants() ... so here is a simple function for you all. Hopefully Zend will include this in the next round as a native php call, without using reflection.
<?php
function GetClassConstants($sClassName) {
$oClass = new ReflectionClass($sClassName);
return $oClass->getConstants());
}
?>
get_class_vars
(PHP 4, PHP 5)
get_class_vars — Restituisce un array con le proprietà di default della classe
Descrizione
array get_class_vars
( string $nome_classe
)
Questa funzione restituisce un array associativo contenente le proprietà di default pubbliche della classe. Gli elementi dell'array prodotto sono nel formato nomevariabile => valore .
Nota: Nelle verioni di PHP precedenti alla 4.2.0, le variabili della classe non inizializzate non sono elencate da get_class_vars().
Example #1 get_class_vars() esempio
<?php
class miaclasse {
var $var1; // questa variabile non ha un valore di default...
var $var2 = "xyz";
var $var3 = 100;
private $var4; // PHP 5
// costruttore
function miaclasse() {
// Modifico qualche proprietà
$this->var1 = "foo";
$this->var2 = "bar";
return(true);
}
}
$mia_classe = new miaclasse();
$variabili = get_class_vars(get_class($mia_classe));
foreach ($variabili as $nome => $valore) {
echo "$nome : $valore\n";
}
?>
Il precedente esempio visualizzerà:
// Versioni di PHP antecedenti alla 4.2.0 var2 : xyz var3 : 100 // Dalla versione 4.2.0 var1: var2 : xyz var3 : 100

This is one of the best php functions. Look at what you can do
class Object
{
var $updtFields;//keep track of affected values
function Object($record="") {
if (is_array($record))
{
$this->updtFields = array();
foreach(array_keys(get_class_vars(get_class($this))) as $k)
if (isset($record[$k]))
{
$this->$k = $record[$k];
$this->updtFields[] = $k;
}
}
}//end of arrayToObject
function toDebug($nl='<br>')
{
foreach(array_keys(get_class_vars(get_class($this))) as $k)
echo "$k = [" . $this->$k . "]{$nl}";
}//end of toDebug
}
Now you can do really cool things. If you have a form like
<form action="" method="post">
<input type="text" name="name" />
<input type="text" name="phone" />
<input type="submit" />
</form>
and you define your class like this
class Person extends Object{
var $name; //same same as in the form
var $phone;
}
when you submmit the form, you can get the data like
$person = new Person($_POST);
//everything in just one line,cool!! Also if you use pear db or adodb when you get data from the database you can do the same thing except use the $row that you get from the database. Remember to ask the result is associative mode.
This is my core Object for everthing I do and it works great.

If you assign a constant value using the self-scope by default to a variable, get_class_vars() will result in a FATAL error.
Example:
<?PHP
class Foo {
const Bar = "error";
public $Foo = self::Bar;
}
print_r(get_class_vars("Foo"));
?>
... but using "Foo::Bar" instead "self::Bar" will work ;)

I wanted a simple ToString() function that was automatic and class independent. I wanted to dump it into any of several classes and get values quickly. I wanted to leave it there so I could customize it for each class, so an outside function wasn't suitable. I came up with this and thought it might be useful. Have fun!
<?php
function ToString () {
$s = "";
$s .= "<table>\n";
$s .= "<tr><td colspan=2><hr></td></tr>\n";
foreach (get_class_vars(get_class($this)) as $name => $value) {
$s .= "<tr><td>$name:</td><td>" . $this->$name . "</td></tr>\n";
}
$s .= "<tr><td colspan=2><hr></td></tr>\n";
$s .= "</table>\n";
return $s;
}
?>

Contrary to multiple comments throughout the manual, get_class_vars() performed within a class can access any public, protected, and private members.
<?php
class Foo {
public $x;
protected $y;
private $z;
public function __sleep() {
return( get_class_vars( __CLASS__ ) );
}
}
?>
works fine (returns x, y, & z). However, given the same class as above,
<?php
print_r( get_class_vars( "Foo" ) );
?>
will NOT return x, y, & z. Instead it will only return the public members (in our case, z).

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
