Bug #17574: variable name $2size allowed

From: php@photography-on-the.net Operating system: Windows XP PHP version: 4.2.0 PHP Bug Type: Variables related Bug description: variable name $2size allowed I POST a form with <select name="2size"> and I read it back with if (isset ($HTTP_POST_VARS['2size'])) {$size = $HTTP_POST_VARS['2size']; } PHP 4.2 accepts this without errors. Isn't this considered an illegal variable name?
