Well its not exactly what I was looking for but you gave me some ideas, but still got this small problem: If I know the value in the array, say for example 49. Then I want to store the previous and next value in the array? I know the other way when I have the position, just use pos($dataarray) then like you sad $dataarray($key+1), that's easy. But the other way???? -----Original Message----- From: Warren Vail [mailto:warren@vailtech.net] Sent: den 25 augusti 2003 09:33 To: Disko_kex; php-windows@lists.php.net Subject: RE: [PHP-WIN] Array question in my experience, using numeric indices to your array, you can deposit and reference occurances as follows; however your reference is not a valid array definition; [0] => 1 [1] => 2 [2] => 3 ... [99] => 100 (I don't believe these are valid as a definition) numeric indices would be defined as follows; array(0 => 1, 1 => 2, 2 => 3 .... 99 => 100); $x = $dataarray[50]; $dataarray[50 - 2] = $x; $dataarray[50 + 1] = $x; if($dataarray[71] == 74) do this.... On the other hand, if the indices is alpha-numeric string representations of numbers, array("0" => 1, "1" => 2, "2" => 3 ... "99" => 100) you will need to use some other tricks to access them. hope this is what you are looking for, you used several terms like "select" and "know the value" of that are somewhat ambiguous ;-) Warren Vail warren@vailtech.net -----Original Message----- From: Disko_kex [mailto:disko_kex@swedish-mushroom.com] Sent: Sunday, August 24, 2003 11:59 PM To: php-windows@lists.php.net Subject: [PHP-WIN] Array question If I have an array like this > [0] => 1 [1] => 2 [2] => 3 ... [99] => 100 If I want to select [50] => 51 and store the value that's 2 positions before and 1 position after, how can I do? If I want to know what position value 71 have? I have search the PHP-manual and found some functions as prev, next, pos etc. But with these commands I have to loop thru the array every time to reach the the values and positions. It has to be an easier way to do it. // jocke -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
