- Synopsis:
- $splice(<variable name> <index> <count> [<text>])
-
- Technical:
- This function removes words from within a string, and then optionally
- replace them with something else. It requires that a variable name be
- given, not an actual variable (meaning the '$' is omitted). If no
- replacement text is given, the words are simply removed. The index
- counts from zero.
-
- Practical:
- This function is useful for changing parts of a string without
- rewriting the whole thing. Used in conjunction with the matching
- functions, it can serve as a search-and-replace function that operates
- on whole words ($sar() operates on individual characters).
-
- Returns:
- text removed from string
-
- Examples:
- @ foo = [one two three four five]
- $splice(foo 1 3 foo bar blah) returns "two three four"
- $splice(foo 0 2) returns "one foo"
- $splice(foo 2 1) returns "five"
- echo $foo shows "bar blah", end result
