PHP extract() function usage example

//Export the array as a variable
$a = 'Original';
$my_array = array("a" => "Cat","b" => "Dog", "c" => "Horse");
extract($my_array); // bbs.it-home.org
echo "$a = $a; $b = $b; $c = $c";
 ?>

Output results: $a = Cat; $b = Dog; $c = Horse

Example 2, using all parameters:

$a = 'Original';
$my_array = array("a" => "Cat","b" => "Dog", " c" => "Horse");
extract($my_array, EXTR_PREFIX_SAME, 'dup');
echo "$a = $a; $b = $b; $c = $c; $dup_a = $dup_a;";
?>

output result: $a = Original; $b = Dog; $c = Horse; $dup_a = Cat;
