Hello,
In this sample script I create an array of objects. Print out their data
with print_r().Update their data with a sub called v_set(). Print out data
showing the chnages using print_r(). I push the altered objects into a new
array and print them out again, still see the updated data. Then I iterate
over the original array again with print_r and the objects lose the updates
and have their original data.
Can anyone explain what I am doing incorrectly?
TIA,
jg
