unset()

I wrote a function inside a file which I included with a require() call. The function takes four arguments by reference (because I need to pass back four values). The first thing it does is to call unset() four times to unset these arguments, so that it can enter new data into them. This will clear the variable values in the calling script of course, but is not a problem because the function needs to clear them so it can put data in them. However it was a surprise to find that the variables contained data when checked on the last line of the function, but when checked in the calling code after the function call had been made, they were empty. Removing the calls to unset() in the function resolved the problem and I have put the unset() calls into the calling code immediately before calling the function. This works but still leaves me with the question. -- ======================================================================= Patrick Dunford, Christchurch, NZ - http://pdunford.godzone.net.nz/ Rejoice in the Lord always.
