Removing duplicate array elements.

[Anon]

Hi! Does anyone know of an easy way to strip out duplicate array elements? I am writing an apache admin package for my company and I am trying to create a drop-down list from an htgroup file. I have no problem using file() to create the array, but many of my groups have several hundred users and thus are broken into multiple lines. I would like to create the array, generate the list but only have one of each element show up in it?

Any suggestions?

Thanks for all your help!

Hi Brendan,

would array_unique() be of any use?

Thanks for the quick response. I did not see this in the functions list before! I will investigate.

In the meantime, I solved my problem by passing a UNIX "uniq" command through exec()

Thanks,

Brendan
