Re: resetting arrays

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Thanks Al,

That's done it!

unset($ses_basket_items[$pos]); $ses_basket_items = array_values($ses_basket_items) ;

They aren't big arrays so I suppose I shouldn't worry about exceeding memory limits - http://uk2.php.net/manual/en/function.array-values.php#36837 ?

My only problem now is that I can't seem to delete the first value of the array.

$basket is the item I want to delete from the array $baskitems....

if (array_search($basket, $baskitems) != FALSE) {
$pos = array_search($basket, $baskitems);
unset($ses_basket_items[$pos]); $ses_basket_items = array_values($ses_basket_items) ;
}

Hi.

I am sure this is easy, but I can't get this work. Is there not a php function that can do this?

I have an array- for example...
[1] => Yellow
[2] => Green
[3] => Purple
[4] => Blue
[5] => Red
[6] => Orange
[7] => Cyan

What happens, say if I delete [3] => Purple?  I get...

[1] => Yellow
[2] => Green
[4] => Blue
[5] => Red
[6] => Orange
[7] => Cyan

But what if I want to reset the numbers? Like...

[1] => Yellow
[2] => Green
[3] => Blue
[4] => Red
[5] => Orange
[6] => Cyan

I've tried this...

unset($ses_basket_items[$pos]); for ($ii=0; $ii<count($ses_basket_items); $ii++) {if (isset($ses_basket_items[$ii])) {$cc++; $arry_a[$cc] = $ses_basket_items[$ii]; }} $ses_basket_items = $arry_a;

where $pos is the position of the array I want to get rid of. $ses_basket_items is session variable, does that matter?

Please help.
