sort 2-d array
Learning PHP. Have a quick question that I hope someone can help me with. simple problem: I have a 2-d 5 column array. First 3 columns are char, and the other 2 are numeric. I would like to sort the array in (1) ascending order of col3, within which (2) ascending order of col4 (when 2 or more rows have same col3).
Whoever can provide me the code, please no user-defined function! I just need basic PHP code; still learning the syntax….. Thanks in advance!
