How to print a multidimensional associative array?

I have the following associative array:

$user["john"]["mozilla"]=1;
$user["john"]["xmms"]=1;
$user["doe"]["mozilla"]=0;
$user["doe"]["office"]=1;
$user["paul"]["mozilla"]=0;
$user["paul"]["xmms"]=1;
$user["paul"]["office"]=1;

How can I print such an associative array using a loop statement like foreach??

Hmmm...

Look it up

http://us3.php.net/foreach

By nesting foreach() statements:

foreach ($user as $name) {
if (is_array($name)) {
foreach ($name as $application) {
echo $application;
}
} else {
echo $name;
}
}

However, if you only need to print it for debugging purposes,
print_r($user) would suite you just fine. Also, you might
want to take a look at var_dump() and var_export():

http://www.php.net/print_r
http://www.php.net/var_dump
http://www.php.net/var_export

you may as well try print_r like in

echo "<pre>";
print_r($user);
echo "</pre>";

Thaks everybody for all thoses suggestions.

I said that I need to print. But actually I need to process every data
on this associative array. That's why print_r doesn't work for me.

So, here is the associative array again,

$user["john"]["mozilla"]=1;
$user["john"]["xmms"]=1;
$user["doe"]["mozilla"]=0;
$user["doe"]["office"]=1;
$user["paul"]["mozilla"]=0;
$user["paul"]["xmms"]=1;
$user["paul"]["office"]=1;

I need the following output in my foreach statement:

john mozilla 1
john xmms 1
doe mozilla 0
doe office 1
etc...

If I got the above output from my associative array, I will be able to
genarate the statistics I need, processing each element (instead of
just printing them).

To expand on NC's example in your format:

foreach ($user as $name => $apps) {
if(is_array($apps)) {
foreach ($apps as $app => $val) {
echo "$name $app $val";
}
} else {
echo $name;
}
}

OK, I give up - here's the fish.

foreach ($user as $fname=>$stats)
{
foreach ($stats as $item=>$value)
{
print "$user -> $item = $value\n";
}
}

Maybe if you spent a minute or two reading what's there on
http://php.net/foreach ,
and trying some code out, you could have solved the problem using far less
effort
than it has taken telling everybody how you don't want to read and learn the
answer
yourself.

I noticed that Message-ID:
<QGwQd.98976$B8.69881@fe3.news.blueyonder.co.uk> from Matt Mitchell
contained the following:

A little ugly, but:

<?php
$user["john"]["mozilla"]=1;
$user["john"]["xmms"]=1;
$user["doe"]["mozilla"]=0;
$user["doe"]["office"]=1;
$user["paul"]["mozilla"]=0;
$user["paul"]["xmms"]=1;
$user["paul"]["office"]=1;

$keys = array_keys($user);
for($i = 0; $i < count($keys); $i++) {
$user_keys = array_keys($user[$keys[$i]]);
for($j = 0; $j < count($user_keys); $j++) {
print($keys[$i] . ' ' . $user_keys[$j] . ' ' .
$user[$keys[$i]][$user_keys[$j]]
.. "\n");
}
}
?>
