{
$temp = $test[$b]['userid'];
if(/*$test[$b]['userid'] !==*/ !array_key_exists($domain1[$d] ['userid']){
//$domain1[$d] = array($test[$b]['userid'] => $tedad) ;
echo $temp;
$end = array(
$domain1[$d] => array(
$temp => $tedad )
);
}
else{
$end[$d][$test[$b]['userid']]= $end[$d][$test[$b]['userid']] +1;

Answer 1

Try:
$result = array();
foreach($test as $t)
{
if(isset($result[$t['domain']][$t['userid']]))
$result[$t['domain']][$t['userid']]++;
else $result[$t['domain']][$t['userid']] = 1;
}
If you don't want to include some domains use like:
$result = array();
foreach($test as $t)
{
if($t['domain'] == 'bing.com')
continue;
if(isset($result[$t['domain']][$t['userid']]))
$result[$t['domain']][$t['userid']]++;
else $result[$t['domain']][$t['userid']] = 1;
}

<?php
$test = array(
array(
'id' => 1,
'domain' => 'google.com',
'userid' => "123"
),
array(
'id' => 2,
'domain' => 'google.com',
'userid' => "456"
),
array(
'id' => 3,
'domain' => 'yahoo.com',
'userid' => "456"
),
array(
'id' => 4,
'domain' => 'google.com',
'userid' => "123"
)
);
echo '<pre>';
print_r($test);
echo '</pre>';
echo '<hr>';
$domains = array();
foreach ($test as $value) {
if (!in_array($value['domain'], $domains))
$domains[$value['domain']] = array();
}
foreach ($domains as $key => $domain) {
foreach ($test as $item) {
if ($key == $item['domain']) {
if (isset($domains[$key][$item['userid']])) {
$domains[$key][$item['userid']] = $domains[$key] [$item['userid']]+1;
} else {
$domains[$key][$item['userid']] = 1;
}
}
}
}
echo '<pre>';
print_r($domains);
echo '</pre>';
echo '<hr>';
// $final = array(
// "google.com" => array(
// "123" => 2,
// "456" => 1
// ),
// "yahoo.com" => array(
// "456" => 1
// )
// );
// echo '<pre>';
// print_r($final);
