Re: [PHP] Comparing array elements
Well, it sounds like something that could be done through the db
query, but if you want to use arrays, it'd be something like this...
$servers = arrray('s1','s2','s3','s4','s5');
$group1 = array('s1','s4','s5');
$in_group = array_intersect($servers, $group1);
$not_in_group = array_diff($servers, $group1);

hey everyone,
Does anyone have and ideas of wisdom on how to compare arrays (mysql result
sets) and group items based on if they exist in two or more arrays?
For example:
I have a table, with a list of servers:
server1
server2
server3
server4
server5
...
serverX
I have a table that specifies which of the servers are grouped:
group1
server1
server4
server5
Now, I want to compare group1 against the server list, and do something like
the following:
In group:
server1
server4
server5
Not in group:
server2
server3
serverX

Re: [PHP] Comparing array elements
Never used those before, that's the way to do it! I think array_search and
in_array are suited for looking up one or two values.

Re: [PHP] Comparing array elements
You can use in_array or array_search. hey everyone, Does anyone have and ideas of wisdom on how to compare arrays (mysql result sets) and group items based on if they exist in two or more arrays?
