duplicates

问题 I have to deal with an xsd schema to generate the java code through jaxb and there is two elements withe same name in one of the sequence.

问题 I need to return all values for: select...where IN (1,2,3,3,3,1) I have a table with unique IDs.

问题 I'm looking for a way to fillNA in duplicated() rows. There are totally same rows and at one time there is a NA, so I decide to fill this one by value of complete row but I don't see how to deal with it.

问题 I have been looking for an answer for this, but none seem to actually help my specific situation. I'm trying to post a list of words and then remove the duplicate data (words) that come from the form. For some reason I can't seem to get array_unique to work. PHP keeps giving me errors saying my post array is a string. But if I try using explode, it says I'm using an array. Really confused right now and very frustrated.
