Re: [PHP] I'm doing something wrong....
In an associative array, there is no notion of the 'n-th' element. So AFAIK you can't do that. cheers, thalis On Wed, 15 May 2002, Robert Rothe wrote: > I've created an array.

When you create an array this way, no numeric indexes are assigned.

Thanks. So the next() and prev() functions just traverse an array using some type of linked list? This is what precludes direct access to specific elements? "Thalis A.

Re: [PHP] I'm doing something wrong....
There is no [0]...only ['one'] and ['two']... Look through the array functions, there may be a way to reassign the keys... ---John Holmes... - Original Message - From: "Robert Rothe" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, May 15, 2002 4:35 PM Subject: [PHP] I'm doing something wrong > I've created an array.

Re: [PHP] I'm doing something wrong....
http://www.php.net/manual/en/language.types.array.php An array in PHP is actually an ordered map. A map is a type that maps values to keys. we're not working with C where each array value is right next to each other in memory. it's an abstraction that does the job intelligently, but gives you a familiar-looking interface. -j Original Message Follows From: Robert Rothe <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: [PHP] I'm doing something wrong Date: Wed, 15 May 2002 17:10:44 -0400 Thanks.

Re: [PHP] I'm doing something wrong....
yah, there's a function. (isn't there almost always?) http://www.php.net/manual/en/function.array-values.php it gives you a numerically indexed array of all the values in your current array, associative or not. -j Original Message Follows From: "1LT John W.

Yup, there is an internal position pointer in every array which are used by most array_ functions. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
