PHP built-in function to assign each element of an array to a variable, does it exist?

For example:

$array = array('f', 'b');
assign($foo, $bar, $array);

// now $foo = 'f' and $bar = 'b'

Does something like this exist in the PHP language? I have never needed something like this before and cannot find anything that will do this.

I just wanted to make sure before I write the function myself - I don't want to write something that already exists within the language.

list ($foo, $bar) = $array;

list() is something like the opposite of array() and its a language construct. Its especially important to know, that even if its listed in the functions reference of the manual (list()), it isn't, because no function is writeable.

you can use php's list() function

$array = array('f', 'b');
list($foo, $bar) = $array;

now it is

$foo = 'f' and $bar = 'b';

php.net/list

Pretty close to PHP's extract() function.

You need to specify the var name as they key for each value in the array though.

$array = array('foo' => 'f', 'bar' => 'b');
extract($array);
// now $foo = 'f' and $bar = 'b'
