I just do it like this for basic arrays

$arr=array("a"=>'1',"b"=>2,'c'=>'3');
foreach($arr as $k=$v){ $$k=$v; }

echo $a; //prints 1
echo $c; //prints 3

EDIT: Check FDL's answer

There is a built-in function for this called extract()

Just use extract():

$arr = array(
    'a' => 1,
    'b' => 2,
    'c' => 3
);
extract($arr);

echo $a; // = 1

extract($arr)

Is the correct answer to this question.

Its generally not considered a good idea though. Whats wrong with $arr['a']?
