Object created using reflection and setValue has empty properties - php

Question

I'm trying to generate an object of class Bar from POST data. I'm doing this using a function that I found here.
I post data from foo.php to bar.php.
bar.php successfully receives the post data and runs the static method Bar::generate, which returns a Bar object.
The problem is, even though the function receives the correct data and knows where to set it, the returned objects properties are empty.
foo.php
<?php
function postArray($array, $destScript){
try {
$ch = curl_init();
if (FALSE === $ch){
throw new Exception('failed to initialize');
}
curl_setopt($ch, CURLOPT_URL,$destScript);
curl_setopt($ch, CURLOPT_POST, count($array));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($array));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$content = curl_exec($ch);
return $content;
if (FALSE === $content)
throw new Exception(curl_error($ch), curl_errno($ch));
} catch(Exception $e) {
trigger_error(sprintf('Curl failed with error #%d: %s', $e->getCode(), $e->getMessage()),E_USER_ERROR);
}
}
echo postArray(array('action' => 'generate', 'first' => 'yes', 'second' => 'no', 'third' => 'maybe'), 'http://herbie.eu/indev/bar.php');
?>
bar.php
<?php
class Bar{
public $first;
public $second;
public $third;
private function __construct($options){
$this->loadFromArray($options);
}
private function loadFromArray($array) {
$class = new ReflectionClass(get_class($this));
$props = $class->getProperties();
foreach($props as $p) {
if (isset($array[$p->getName()])){
$p->setValue($this, $array[$p->getName]);
echo $p->getName()." = ".$array[$p->getName()]."<br>";
}
}
echo "<br>";
}
static public function generate($options){
try{
return new Bar($options);
}
catch(NotFoundException $unfe){
echo 'Bar::generate failed + '.$unfe;
return NULL;
}
}
}
if(!empty($_POST['action'])){
if($_POST['action'] == "generate"){
$booking = Bar::generate($_POST);
echo "success ".count($_POST)."<br>";
print_r($booking);
}
}
else{
echo "WARNING_L0: ${_POST}['action'] not set";
}
?>
Running foo.php returns,
first = yes
second = no
third = maybe
success 4
Bar Object ( [first] => [second] => [third] => )
As you can see, the ReflectionClass in loadFromArray knows exactly what to put where, but the returned object is empty. The 4 is the result of count($_POST).
