PHP Variables from another var

Question

This may sound confusing:

$myVar = "Helloooo!";
$text = "myVar";

How could i call $myVar from just the fact $text is filled with the variable name, perhaps this ? (it doesnt work though)

echo $($text);

It may be best to avoid this. It's very fragile and error prone. You can achieve the same results using an array, like setting $a[$myVar] and using it instead of $$myVar. — Vinko Vrsalovic, Dec 22 '09 at 17:52

PHP has a feature called "variable variables", that works exactly like you need it to.

You can use it almost like you posted, but without the brackets:

echo $$text;

The best notation is using curly braces however, as that removes ambiguities when dealing with arrays.

echo ${$text};
