#29787 [NEW]: Object instance variables not visible from within __toString()

From: adamgoossens at users dot sourceforge dot net Operating system: Windows XP Professional, SP2 PHP version: 5.0.1 PHP Bug Type: Zend Engine 2 problem Bug description: Object instance variables not visible from within __toString() Description: ------------ Hi folks, When overriding __toString() to provide custom object to string conversion it appears as though object level variables are not visible from within the function. This affects public, private and protected variables equally. Static member variables and class constants are not affected. Reproduce code: --------------- class Foo { public $_myVar; public static $_static = 'I am static.'; const MY_CONST = 'I am constant.'; function __construct() { $_myVar = 'A public variable.'; } function __toString() { return "Variables:\n".$this->_myVar."\n".Foo::$_static."\n".Foo::MY_CONST; } } $foo = new Foo; echo $foo; Expected result: ---------------- Variables: A public variable. I am static. I am constant. Actual result: -------------- Variables: I am static. I am constant. -- Edit bug report at http://bugs.php.net/?id=29787&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=29787&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=29787&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=29787&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=29787&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=29787&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=29787&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=29787&r=needscript Try newer version: http://bugs.php.net/fix.php?id=29787&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=29787&r=support Expected behavior: http://bugs.php.net/fix.php?id=29787&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=29787&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=29787&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=29787&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=29787&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=29787&r=dst IIS Stability: http://bugs.php.net/fix.php?id=29787&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=29787&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=29787&r=float
