Req #63879 [NEW]: add cast_object (to ARRAY) to SplFixedArray
From: gynvael at coldwind dot pl
Operating system: any
PHP version: 5.4.10
Package: SPL related
Bug Type: Feature/Change Request
Bug description:add cast_object (to ARRAY) to SplFixedArray
Description:
------------
When comparing (using == operator) an ARRAY with SplFixedArray object one
always
gets "false", even if arrays are exact match.
However, casting SplFixedArray to (array) beforehand does a correct (as far
as
the == operator goes anyway) comparison.
For convenience it would be good to add a cast_object handler that does the
same
thing that SplFixedArray::toArray function does (returns a PHP ARRAY
matching
the SplFixedArray objects content).
Details:
The == operator uses cast_object handler when comparing ARRAY with
SplFixedArray
object. The SplFixedArray has the default PHP cast_object handler
(zend_std_cast_object_tostring), which fails to convert SplFixedArray to
ARRAY.
In such case the comparison is always false (not equal).
Adding a custom cast_object handler to SplFixedArray that does the same
thing
that ::toArray function does, would enable a developer to use $splarray ==
$array to perform a comparison, instead of using an explicit cast or
calling the
toArray() function explicitly (see example code below).
Test script:
---------------
<?php
$arr = array(1,2,3);
$splarr = SplFixedArray::fromArray($arr);
var_dump($splarr == $arr); // Not Equal (should be)
var_dump((array)$splarr == $arr); // Equal
var_dump($splarr->toArray() == $arr); // Equal
Expected result:
----------------
bool(true)
bool(true)
bool(true)
Actual result:
--------------
bool(false)
bool(true)
bool(true)
