There is another important difference between splice and substr that should be mentioned. If you call 
substr EXPR,OFFSET,LENGTH
substr EXPR,OFFSET

[download]
This will not erase anything in the string while if you use 
splice ARRAY,OFFSET,LENGTH
splice ARRAY,OFFSET

[download]
You will erase elements from the array

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
