Previous Comments: ------------------------------------------------------------------------ [2004-08-22 17:52:20] helly@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php You didn\'t set the public var so its value is NULL. ------------------------------------------------------------------------ [2004-08-22 14:56:42] adamgoossens at users dot sourceforge dot net 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 this bug report at http://bugs.php.net/?id=29787&edit=1
