Maybe, simpler example.
OK:
$c = array('01'=>3, '03'=>10);
$d = array('05'=>44, '07'=>3);
var_dump(array_merge($c,$d));
Failed:
$a = array('01'=>1, '02'=>73);
$b = array('10'=>11, '11'=>23);
var_dump(array_merge($a,$b));

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("777777777777777777777777777777777777777777777777777777777"=>
array("I'm string of digits too"))));
var_dump(is_string("42424242"));
var_dump(is_string(42424242));
var_dump(is_string("777777777777777777777777777777777777777777777777777777777"));
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) {
["777777777777777777777777777777777777777777777777777777777"]=>
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) {
["777777777777777777777777777777777777777777777777777777777"]=>
array(1) {
[0]=>
string(24) "I'm string of digits too"
}
}
bool(true)
bool(false)
bool(true)
