Description:
array_merge interprets string keys, containing only digits as numeric
keys, if numeric overflow not reached.
String keys should works as strings regarless of their contents.
Test script:
---
var_dump(array_merge(array('t777'=> array("I'm a string";
var_dump(array_merge(array("42424242"=> array("I'm a string of
digits";
var_dump(array_merge(array("7"=>
array("I'm string of digits too";
var_dump(is_string("42424242"));
var_dump(is_string(42424242));
var_dump(is_string("7"));
Expected result:
array(1) {
["t777"]=>
array(1) {
[0]=>
string(12) "I'm a string"
}
}
array(1) {
["42424242"]=>
array(1) {
[0]=>
string(22) "I'm a string of digits"
}
}
array(1) {
["7"]=>
array(1) {
[0]=>
string(24) "I'm string of digits too"
}
}
bool(true)
bool(false)
bool(true)
Actual result:
--
array(1) {
["t777"]=>
array(1) {
[0]=>
string(12) "I'm a string"
}
}
array(1) {
[0]=>
array(1) {
[0]=>
string(22) "I'm a string of digits"
}
}
array(1) {
["7"]=>
array(1) {
[0]=>
string(24) "I'm string of digits too"
}

#41372 [Bgs->Opn]: Internal pointer of source array resets during array copying
ID: 41372
User updated by: forjest at gmail dot com

-Status: Bogus

Bug Type: Arrays related
Operating System: WinXP, Linux
PHP Version: 4.4.7
New Comment:
I'm described problem, that is not foreach related. Just
1. Straight copy from one global scope variable to another
2. Copy from current runing context to global variable.
Not iterating local varibale after copying element of global array.
This is another bug, but may be from same "family".
And please remember another one http://bugs.php.net/bug.php?id=37715
Problem appeared at 4.4.2 and 5.1.2 and was reported year ago...
May be I'm described duplicate of "This is expected and not going to be
changed" bug instead of assigned 'foreach' bug?

Description:
Bug first appeared in 4.4.2. Version 4.4.1 works okay.
5.1.4, 5.2.1 has this bug too.
-
Seems algorithm of array copying was changed at 4.4.2 and 5.1.2
versions.
-
This behavior cause problems in unexpected situations such as error
handling functions, when array pointer reseted due copying from another
array which reference to it.
Reproduce code:
---
$Foo = array('val1', 'val2', 'val3');
end($Foo);
var_dump(key($Foo));
$MagicInternalPointerResetter = $Foo;
var_dump(key($Foo));
