Re: in_array() 4.0.0 -> 4.0.2

Rasmus, The purpose of in_array() is to say if an item is in the array, with a rather nice side effect of re-positioning the array pointer to that element. How are we to find the position of the element? I don't want to have to do an expensive for loop every time I want to get an index. Short of coding up a my_in_array() what are the alternatives? regards, David. ----- Original Message ----- From: Rasmus Lerdorf <rasmus@php.net> To: David Newcomb <davidn@vnvi.com> Cc: php-general <php-general@lists.php.net> Sent: Thursday, September 07, 2000 7:07 PM Subject: Re: [PHP] in_array() 4.0.0 -> 4.0.2 > > The functionality of in_array has changed between 4.0.0 -> 4.0.2 > > > > The difference is that in x.2 in_array() moves the internal array > > pointer to the found item; and in x.0 it dose not. > > > > Can anyone tell me why the change was made?
