[RESOLVED] associative array

nuttynibbles

hi, i've got a Q on associative array..

for example:

$array = array("ID"=>"1234","Country"=> "France","age"=> "25");

so now i wanna extract the diff value into their respective variable..

e.g
$ID=1234;
$Country="France";
$age = "25";

how do i do this.. thks

hey tks.. i research on it.. =)

what if my array ID(ID number) has space..
e.g.$array = array("ID number"=>"1234");

In that case, I think you'll have to create your own extract() function, something like:

function safe_extract($var) {
    foreach($var as $key => $value)
        $GLOBALS[str_replace(' ', '_', $key)] = $value;
}

Obviously this doesn't contain any of the fancy features of extract(), such as the different extraction modes... but you can feel free to implement those if you wish 😉

well cud u explain on ur code? =) is $GLOBALS[str_replace] a method or self name variable?

nuttynibbles

hey tks i think i got it. because my array ID got space in between, i use array_values:

$array = array(""=>"1234","Country"=> "France","age"=> "25");
list($id, $country, $age) = array_values($array);

To explain my code, it goes through the array you pass to the function and creates variables out of the array keys, just like extract() does. The $GLOBALS array is a superglobal array (defined here: [man]variables.predefined[/man]), so by adding the new variable to that array, it's as if you created a variable in the global scope. All I do is use the $key of the array item, run it through str_replace() to get rid of any spaces, and use that as the key for our new variable.

If you know that the order never changes, you can of course use the list() method you showed. Either way, don't forget to mark this thread resolved (if it is).
