There has to be something wrong with your arrays then, 'cause this works perfectly fine:

<?
$a = array('a' => 'a', 'b' => 'b');
$b = array('c' => 'c', 'd' => 'd');

$c = array_merge($a, $b);

foreach ($c as $i) {
	print $i . "\n";
}
?>

Anything is possible...but I think everything is okay. In any event, here is some data for ya:

I wrote my own INI parser for reasons listed in the code below:

function ini_parse($filename)
{
//=================================================
// Since parse_ini_file() has probs with '=' and '&'
// characters in values, parse the ini file ourselves
//=================================================

$fp = fopen($filename, 'r');
while(!feof($fp)) {
	$line = trim(fgets($fp, 1024));
	if($line[0] == "[" && $line[strlen($line) - 1] == "]") {
		$sec_name = substr($line, 1, strlen($line) - 2);
 	} elseif ($line[0] == ";") {
		// do nothing...';' denotes a comment line
   	} else {
		$pos = strpos($line, "=");
		$property = substr($line, 0, $pos);
		$value = substr($line, $pos + 1, strlen($line) - $pos - 1);
		$ini_array[$sec_name][$property] = $value;
	}
}
return $ini_array;

}[/b]

I call this function twice and build the array(s) like this:

$ini_array = ini_parse(fn_resolve($HTTP_SERVER_VARS['HTTP_HOST'], "", $root_ini)) + ini_parse(fn_resolve($HTTP_SERVER_VARS['HTTP_HOST'], "", $user_ini));

...where $root_ini and $user_ini are variables holding filenames. I've also tried the array_merge function as well:

$ini_array = array_merge( ini_parse(fn_resolve($HTTP_SERVER_VARS['HTTP_HOST'], "", $root_ini)), ini_parse(fn_resolve($HTTP_SERVER_VARS['HTTP_HOST'], "", $user_ini)) );

...with no luck. If I run the function on the ini files and then print_r them out individually, they are listing correctly so as far as I can tell the arrays are fine.

Any ideas.

I'd suggest you do some more debugging, 'cause the code you posted works perfectly fine. I tried this script:

<?
function ini_parse($filename)
{
//=================================================
// Since parse_ini_file() has probs with '=' and '&'
// characters in values, parse the ini file ourselves
//=================================================

$fp = fopen($filename, 'r');
while(!feof($fp)) {
	$line = trim(fgets($fp, 1024));
	if($line[0] == "[" && $line[strlen($line) - 1] == "]") {
		$sec_name = substr($line, 1, strlen($line) - 2);
	} elseif ($line[0] == ";") {
		// do nothing...';' denotes a comment line
	} else {
		$pos = strpos($line, "=");
		$property = substr($line, 0, $pos);
		$value = substr($line, $pos + 1, strlen($line) - $pos - 1);
		$ini_array[$sec_name][$property] = $value;
	}
}
return $ini_array;
}

$root_ini = "test.dat";
$user_ini = "test2.dat";

$ini_array = array_merge( ini_parse($root_ini), ini_parse($user_ini) ); 

print_r($ini_array);
?>

Then test.dat is just
[section1]
a=a
b=b

and test2.dat is
[section2]
c=c
d=d

And the output is correct...

The only thing that I changed was the fn_resolve, 'cause I don't know what it does and you didn't provide the code for it...but besides that, everything else works perfectly fine.

FYI: fn_resolve is a function that I built to resolve filenames based on how the filename is passed:

/filename = base or root location
./filename = current dir
filename = current dir
http://someserver/filename = web location
etc.
