php array foreach results with selected values

php array foreach results with selected values

I have a PHP array as follows:
Array
(
[2] => Array
(
[_diskquota] => 524288000
[_diskused] => 0
[diskquota] => 500
[diskused] => 0
[diskusedpercent] => 0
[diskusedpercent20] => 0
[domain] => domain1.com
[email] => aaa@domain1.com
[humandiskquota] => 500 MB
[humandiskused] => None
[login] => aaa@domain1.com
[mtime] => 1378636684
[txtdiskquota] => 500
[user] => aaa
)
[3] => Array
(
[_diskquota] => 0
[_diskused] => 0
[diskquota] => unlimited
[diskused] => 0
[diskusedpercent] => 0
[diskusedpercent20] => 0
[domain] => domain2.com
[email] => ddd@domain2.com
[humandiskquota] => None
[humandiskused] => None
[login] => ddd@domain2.com
[mtime] => 1378636684
[txtdiskquota] => unlimited
[user] => ddd
)
[4] => Array
(
[_diskquota] => 104857600
[_diskused] => 0
[diskquota] => 100
[diskused] => 0
[diskusedpercent] => 0
[diskusedpercent20] => 0
[domain] => domain3.com
[email] => sss@domain3.com
[humandiskquota] => 100 MB
[humandiskused] => None
[login] => sss@domain3.com
[mtime] => 1378636684
[txtdiskquota] => 100
[user] => sss
)
)
How can I get results like this in php foreach? (I don't want in list
other values)
email | humandiskquota | humandiskused
my code for try. foreach is woiking but I can't get just email value from
array.
foreach ($d as $arr => $key)
{
foreach ($key as $k => $v)
{
//echo "$k: $v<br>";
echo $email=$k['email'].' | ';
echo $email=$v['email'].' | ';
echo $email=$v->email.' | ';
echo $email=$k->email.' | ';
}
echo "<br>";
}
