Philip Posted June 28, 2009 Share Posted June 28, 2009 You're calling $$a, which looks for the variable with the value of $a or - $Hello. You obviously haven't set it up yet..... You could do: $a = 'Hello'; $hello = 'Hello everyone'; // ... $$a = 'Something'; echo $hello.'<br />'; echo $aa.'<br />'; Link to comment https://forums.phpfreaks.com/topic/163948-variables/#findComment-864907 Share on other sites More sharing options...
