Subject: php5: Reflection object fails to recognise runtime class properties as public

Date: Wed, 30 Jan 2008 16:17:33 +0000

Package: php5
Version: 5.2.0-8+etch10
Severity: important

According to a friend, the code below works correctly on PHP 5.2.3 but in the current Debian stable distribuion it fails to produce the right result. Note that the 
myRuntimeProperty is absent from the second var_dump at the end.

<?php

class Test
{
    public $myDeclaredProperty = 1;

    public function __construct()
    {
        $this->myRuntimeProperty = 2;
    }

    public function getPublicProperties()
    {
        $r = new ReflectionObject($this);
        $properties = $r->getProperties();
        $publicProperties = array();
        foreach ($properties as $property) {
            if ($property->isPublic()) {
                $publicProperties[$property->getName()] = 
$property->getValue($this);
            }
        }
        return $publicProperties;
    }
}
echo 'Running ' . phpversion() . "\n";
$obj = new Test();
echo "Dumping object:\n";
var_dump($obj);
echo "Dumping public properties according to Reflection object\n";
var_dump($obj->getPublicProperties());


My output:

Running 5.2.0-8+etch10
Dumping object:
object(Test)#1 (2) {
  ["myDeclaredProperty"]=>
  int(1)
  ["myRuntimeProperty"]=>
  int(2)
}
Dumping public properties according to Reflection object
array(1) {
  ["myDeclaredProperty"]=>
  int(1)
}

Running 5.2.5-1

  ["myRuntimeProperty"]=>
  int(2)
}
Dumping public properties according to Reflection object

  ["myRuntimeProperty"]=>
  int(2)
}

Running 5.2.0-8+etch10

  ["myRuntimeProperty"]=>

Dumping public properties according to Reflection object
Segmentation fault

That looks even worst.

I'll try to provide a backtrace as soon as I recompile php5 with the
debug symbols.

Version: 5.2.6.dfsg.1-1+lenny4

Hi,
I am closing this bug report since it applies to version in oldstable
which is no longer supported. According to bugreport code in question
works fine in newer versions of php5.
