#47369 [NEW]: use of {self::$} in a string always triggers Notice: Undefined variable:

From: d4n at digitalanalogue dot org Operating system: CentOS 5 PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: use of {self::$} in a string always triggers Notice: Undefined variable: Description: ------------ Can you update the strings document to explain why you cannot use self::$var in any string, or if you can what php version it works in. I do not know if this is a bug, or if it is my php version, but I can't understand why I can access the var and echo it out yet when I put it in a string using escaped methods it is ignored and throws a notice saying undefined when it clearly is! Thanks Dan Reproduce code: --------------- class user { private static $table = "foo"; public function user() { //blah... } public static function test() { $str = "table = ". self::$table . "<br/>"; echo $str; // Outputs: table = foo $str = "table = {self::$table} <br/>"; echo $str; // Outputs: // Notice: Undefined variable: table in /*** on line *** $str = '{self::$table}' . "<br/>"; echo $str; // Outputs: table = {self::} $str = <<<EOD table = self::$table EOD; /* Outputs: Notice: Undefined variable: table in /*** on line *** table = self:: */ echo $str; } } Expected result: ---------------- table = foo table = foo table = {self::$table} table = foo Actual result: -------------- table = foo Notice: Undefined variable: table in /*** on line *** table = {self::} table = {self::$table} // correct!
