array_merge() doesn't work if there are objects in your array.
Here is a small test case.
<?php
class test
{
var $one;
var $two;
function test($one, &$two) {
$this->one = $one;
$this->two = &$two;
}
}
$x = 6;
$a = new test(1, &$x);
$b = new test(2, &$x);
$c = new test(3, &$x);
$aa = array($a, $b, $c);
$d = new test(4, &$x);
$e = new test(5, &$x);
$f = new test(1, &$x);
$bb = array($d, $e, $f);
$arr = array_merge($aa, $bb); // array_merge_recursive doesn't do this
either
var_dump($arr);
?>
The results
array(6) {
[0]=>
object(test)(2) {
["one"]=>
int(1)
["two"]=>
&int(6)
}
[1]=>
object(test)(2) {
["one"]=>
int(2)
["two"]=>
&int(6)
}
[2]=>
object(test)(2) {
["one"]=>
int(3)
["two"]=>
&int(6)
}
[3]=>
object(test)(2) {
["one"]=>
int(4)
["two"]=>
&int(6)
}
[4]=>
object(test)(2) {
["one"]=>
int(5)
["two"]=>
&int(6)
}
[5]=>
object(test)(2) {
["one"]=>
int(1)
["two"]=>
&int(6)
}
}
It should only be a FIVE element array. As elements 0 and 5 are exactly the
same.
I can only assume that this is beyond the scope of the function, but why?
Seems like it would be pretty easy to do.
