see this function:
function super_unique($array)
{
$result = array_map("unserialize", array_unique(array_map("serialize", $array)));
foreach ($result as $key => $value)
{
if ( is_array($value) )
{
$result[$key] = super_unique($value);
}
}
return $result;
}use it like: $array = array(
1 => array('id' => '12','name' => 'Great man'),
1 => array('id' => '12','name' => 'Great man'),
3 => array('id' => '12','name' => 'Great man'),
4 => array('id' => '14','name' => 'Lamborgini'),
5 => array('id' => '14','name' => 'Lamborgini'),
6 => array('id' => '14','name' => 'Lamborgini'),
7 => array('id' => '14','name' => 'Lamborgini'),
8 => array('id' => '29','name' => 'Leon'),
9 => array('id' => '29','name' => 'Leon'),
10 => array('id' => '29','name' => 'Leon'),
11 => array('id' => '29','name' => 'Leon'),
11 => array('id' => '29','name' => 'Leon'),
);
print_r(super_unique($array));

how can i return an array like :
[php]
$array = array(
1 => array('id' => '12','name' => 'Great man'),
2 => array('id' => '14','name' => 'Lamborgini'),
3 => array('id' => '29','name' => 'Leon'),
);
[/php]
[color=red]please attention to first keys[/color] You got it right, what is the problem? you can use $array like any PHP var.
e.g.:[php]foreach($array as $value)
{
// now use $value['id'] or $value['name'];
// sample:
echo 'ID: '.$value['id'].'<br/>';
echo 'NAME: '.$value['name'].'<br/>';
}
[/php]and[php]$great_man = $array[1];
echo 'id: '.$great_man['id'].' name: '.$great_man['name'];
[/php]
is this not working?
$array = array(
1 => array('id' => '12','name' => 'Great man'),
1 => array('id' => '12','name' => 'Great man'),
3 => array('id' => '12','name' => 'Great man'),
4 => array('id' => '14','name' => 'Lamborgini'),
5 => array('id' => '14','name' => 'Lamborgini'),
6 => array('id' => '14','name' => 'Lamborgini'),
7 => array('id' => '14','name' => 'Lamborgini'),
8 => array('id' => '29','name' => 'Leon'),
9 => array('id' => '29','name' => 'Leon'),
10 => array('id' => '29','name' => 'Leon'),
11 => array('id' => '29','name' => 'Leon'),
11 => array('id' => '29','name' => 'Leon'),
);
//one
print_r($array);
//two
print_r(array_unique($array));
