How to print a multidimensional associative array?

[Leonardo]

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...

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

foreach??

you may as well try print_r like in

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

Re: How to print a multidimensiona l associative array?

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 => $apps) {
if(is_array($ap ps)) {
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.

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;

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

But ugly is bad in the long run. Works now, yes... but how about later,
when you want to change, add, debug, or modify the thing?

Matt Mitchell's example is way better.

"Give a man a fish, and you feedcx him for a day; teach a man how to fish,
and you feed him for life."

I heard a much much better version the other day:

"Give a man a hot meal, and you'll keep him warm for an hour. Set a man on
fire, and you'll keep him warm for the rest of his life."

Somehow it sprang to mind when I was reading this thread...

I know you got it - just thought you might find the alternative version
amusing!...
