[PHP] Extracting Array value as variable
I have an array $veg that is set so $veg[0]="broccoi" & $veg[1]="tomatotes". I have also assigned values to the variables $broccoli=1 and $tomatoes=2. I want to print the values for those variables ($broccoli and $tomatoes) by only using the $veg array. So, if it worked it would be $$veg[0] would be 1, and $$veg[1] would be 2. Is there anyway to do this? Many thanks!

An example :
'apple',
'b' => 'banana',
'c' => 'cranberry');
print $array['a']; // apple
print $array['b']; // banana
extract($array);
print $a;// apple
print $b;// banana
$var = 'array';
print ${$var}['a']; // apple
print ${$var}['b']; // banana
?>

It always amazes me that people are so afraid of simply trying. Yes, there is a way to do this.
