I have to clean a huge array in wich every element is a text line. My cleaning consists in deleting each item if it appears more than one time.
I cannot use hashes and I'd prefer avoiding foreach cycles (I have a lot of arrays, and so...).
I searched a function wich works in this way, but I did'n find it. It ssems impossible to me, but it misses to perl?
someone can help me?
thanks!
