php变量与数组的相互转换(extract与compact)_PHP教程

//多个变量转数组
$name='phpff';
$email='phpff@phpff.com';
$info=compact('name','email');//传递变量名
print_r($info);
/*
Array
(
[name] => phpff
[email] => phpff@phpff.com
)
*/
?>

//数组转多个变量
$capitalcities['England'] = 'London';
$capitalcities['Scotland'] = 'Edinburgh';
$capitalcities['Wales'] = 'Cardiff';
extract($capitalcities);//转变成三个变量 England，Scotland，Wales
print $Wales;//Cardiff

?>

$my_array = array("a" => "Cat","b" => "Dog", "c" => "Horse");
extract($my_array);
echo "$a = $a; $b = $b; $c = $c";
?>
