This might be interesting ...

The function extract() allows you to extract all values from an array 
and prefix them with a specified string. What I didn't know until 
just a second ago was that you can supply a function as a string, so 

$my_array = array("a","b","c","d",array("a","b","c","d"));

$i = 1;


print "<pre>";

print $SOMEVAL_1;
print $SOMEVAL_2;
print $SOMEVAL_3;
print $SOMEVAL_4;
print $SOMEVAL_5;

print "</pre>";

... will produce:


Which is cool. Not quite what you wanted, but maybe you could run with it.
