Bug description: Behavioural issues: $foo = array() vs $foo[] and objects vs resources
Description:
------------
This bug report pertains to two seperate but related problems:
1. Unexpected and undocumented behaviour, between $foo[] and $foo =
array()
2. Automatic conversion of objects to strings when used as the key in an
array.
Part 1;
-------
With a given resource, the automatic casting of a resource to an interger
differs based on the method of array creation.
This is both unexpected, and undocumented behaviour. I can see no reason
why this would be a feature, rather than a bug.
I suggest the behaviour be changed to be consistant with both methods of
array creation.
Part 2;
------
When an object is used as the key of an array (with behaviour changing
between method of array creation), should n't the object be casted to an
interger or the __toString method called?
When used with array() no error is thrown, the array is simply empty. With
$foo[__object__] an error is thrown.
I suggest the behaviour of objects as array keys be changed to be
consistant with that of resources.
The code in the reproduce code section demonstrates both aspects of the
behavioural issue.
Reproduce code:
---------------
<?php
// Create a sample object
class id_obj { var $_id; function id_obj($id) { $this->_id = $id; } }
// Create two new objects
$id1 = new id_obj(1);
$id2 = new id_obj(2);
// Add them to an array with two different methods
$array = array(); $array[$id1] = 'foo';
$array2 = array ($id1 => 'id1', $id2 => 'id2');
echo "objects: first method:\n";
var_dump($array);
echo "objects: second method:\n";
var_dump($array2);
// Create two resources
$fp1 = fsockopen("www.example.com", 80, $errno, $errstr, 30);
$fp2 = fsockopen("www.example.com", 80, $errno, $errstr, 30);
// Add them to an array with two different methods
$resarray = array(); $resarray[$fp1] = 'fp1';
$resarray2 = array($fp1 => 'fp1', $fp2 => 'fp2');
// Show the result
echo "resources: first method:\n";
var_dump($resarray);
echo "resources: second method:\n";
var_dump($resarray2);
?>
