Bug Type: Feature/Change Request
Bug description:Extend array assignment operator ('=>')
Description:
------------
This feature would allow one to define a value to be used for creating
multiple
array indexes (think of it as an array "fill" with a tad more flexibility).
The
"flexibility" is that rather than using a numerical starting index value
and a
length parameter, this new syntax would set the same value for each value
in a
1-dimensional array of scalars (used as keys).
This syntax is essentially a more convenient/concise way of doing something
like:
foreach($array_of_keys as $key)
$the_array[$key] = $value_for_keys;
with the added bonus that it would work both when defining an entire array
or
just
modifying an existing array. These two use case scenarios are modeled below
as
Use
Case #1 and #2, respectively.
Test script:
---------------
<?php
/* ---------------------- Use Case #1 ---------------------- */
// set/clear appropriate bits at intialization/definition
$binary = array(
range( 0, 0) => 1,
range( 1, 1) => 0,
range( 2, 3) => 1,
range( 4, 11) => 0,
range(12, 15) => 1
);
/* ---------------------- Use Case #2 ---------------------- */
// initialize array representation of 16-bit binary number to 0
$binary = array_fill(0, 16, 0);
// set appropriate bits
$binary[range( 0, 0)] = 1;
$binary[range( 2, 3)] = 1;
$binary[range(12, 15)] = 0;
?>
