Can you redeclare a variable?
Say I made var $temp[] an array and put stuff into it, could i then redeclare temp as var $temp = 4
or maybe var $temp[], another array, but completly clear? or would it hold a risidual ?
If not is it possible to wipe an arrays content?
In java we used to dump and drop variables all over the place, a string could be an integer, then a char, then a float or a double at a whim. :huh:
