Log: Add a __wakeup() method to SplFixedArray, thereby fixing serialising an
SplFixedArray object and bug #60560 (SplFixedArray un-/serialize, getSize(),
count() return 0, keys are strings).
------------------------------------------------------------------------

Quick fix is to store in serialized form internal array:
-------------------------------------
$sa = serialize($a->toArray());
$ua = unserialize($sa);
$b = SplFixedArray::fromArray($ua);
var_dump($b);
echo 'Sizeof $b = ' . $b->getSize(), PHP_EOL;
echo 'Count $b = ' . $b->count(), PHP_EOL;
-------------------------------------
Gives the expected results
Also I forgot in php >= 5.4.0RC3 (should I report this as separate bug?)
The actual result of var_dump($b) is:
$b = object(SplFixedArray)#2 (2) {
["0"]=>
int(1)
["1"]=>
int(2)
}
The keys are strings and not integers and this causes
-------------------------------------
$b = unserialize(serialize($a));
SplFixedArray::fromArray($b->toarray());
-------------------------------------
To throw an exception 'InvalidArgumentException' with message 'array must
contain only positive integer keys'

Description:
------------
If SplFixedArray object is created via unserialize() of serialized instance
then the getSize() and count() methods return 0 instead of expected actual size.
Tested on Debian Squeeze 6 64bit:
x86-5.4.0RC3-dev
Tested on windows 7 64bit:
x86-5.4.0RC3-nts
x86-5.4.0trunk(12.12)-nts
x86-5.4.0snap(13.12)-nts

x86-5.3.6-nts
x64-5.3.6-nts
x86-5.3.4-nts
x86-5.3.1-ts
Test script:
---------------
<?php
$a = new SplFixedArray(2);
$a[0] = 1;
$a[1] = 2;
echo '$a = ', var_dump($a);
echo 'Sizeof $a = ' . $a->getSize(), PHP_EOL;
echo 'Count $a = ' . $a->count(), PHP_EOL;
echo PHP_EOL;
$b = unserialize(serialize($a));
echo '$b = ', var_dump($b);
echo 'Sizeof $b = ' . $b->getSize(), PHP_EOL;
echo 'Count $b = ' . $b->count(), PHP_EOL;
Expected result:
----------------
$a = object(SplFixedArray)#1 (2) {
[0]=>
int(1)
[1]=>
int(2)
}
Sizeof $a = 2
Count $a = 2
$b = object(SplFixedArray)#2 (2) {
[0]=>
int(1)
[1]=>
int(2)
}
Sizeof $b = 2
Count $b = 2
Actual result:
--------------
$a = object(SplFixedArray)#1 (2) {
[0]=>
int(1)
[1]=>
int(2)
}
Sizeof $a = 2
Count $a = 2
$b = object(SplFixedArray)#2 (2) {
[0]=>
int(1)
[1]=>
int(2)
}
Sizeof $b = 0
Count $b = 0
