Hello,

What is the fastes way to add string prefixes to array keys?

was

$array = array(
 '1' => 'val1',
 '2' => 'val2',
);

needed

$array = array(
  'prefix1' => 'val1',
  'prefix2' => 'val2',
);

According to http://www.phpbench.com/ (see Modify Loop) I should use "for" statement, but probably there is more elegant way?

Thank you.
