Description
Copy parts out of an array and return them as a new array
Parameters
There is no limit.
Remarks
All actions apply to the array and only return VALUES not keys.
Splicing can overlap and return the same item more than once.
Spicing likes to use patterns such as:
'A'..'Z' c65..c69 0..10 10..0 0x0A..0x65 $valuea to $valueb
If anything else is entered it will return the KEY that it links to.
Example
Extract elements 0 to 3 from an array
$Test = array("Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight"); printr($Test[0..3]);
Extract elements 3 to 0 from an array
$Test = array("Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight"); printr($Test[3..0]);
Extract elements 0 to 3 AND 5 to 6 from an array
$Test = array("Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight"); printr($Test[0..3, 5..6]);
Extract elements 0 to 3 AND 5 to 6 AND 7 from an array
$Test = array("Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight"); printr($Test[0..3, 5..6, 7]);
Extract elements 0 to 3 AND 5 to 6 AND 7 to 1 from an array
$Test = array("Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight"); printr($Test[0..3, 5..6, 7..1]);
Extract a value out a dictionary (For whatever reason)
$Test = array( "A" => "Zero", "B" => "One", "C" => "Two", "D" => "Three", "E" => "Four", "F" => "Five", "G" => "Six", "H" => "Seven", "I" => "Eight"); printr($Test['G']);
Extract a some of values out a dictionary
$Test = array( "A" => "Zero", "B" => "One", "C" => "Two", "D" => "Three", "E" => "Four", "F" => "Five", "G" => "Six", "H" => "Seven", "I" => "Eight"); printr($Test['G'..'H']);
Extract a series of values out a dictionary
$Test = array( "A" => "Zero", "B" => "One", "C" => "Two", "D" => "Three", "E" => "Four", "F" => "Five", "G" => "Six", "H" => "Seven", "I" => "Eight"); printr($Test['G'..'H', 'F'..'D', 'B']);
