Hi,
I am testing an example of removing duplicates from an array. What i want to do is check to see which has a lower ‘Value’ and if it has a duplicate then remove the one with a lower value.
So for example, with this code i am trying out:
$items = array
(
'x' => array
(
'y' => array
(
0 => array
(
'ID' => 390517,
'Name' => 'Bill',
'Value' => 80
),
1 => array
(
'ID' => 390519,
'Name' => 'Mike',
'Value' => 85
),
2 => array
(
'ID' => 390533,
'Name' => 'Sam',
'Value' => 55
),
3 => array
(
'ID' => 390519,
'Name' => 'Mike',
'Value' => 95
)
)
)
);
/**
* remove duplicates of higher value
*/
$a = $items['x']['y'];
$k = count($a);
for($i=0; $i < $k-1; $i++)
{
for($j=$i+1; $j < $k; $j++)
{
if ($a[$i] == $a[$j]) unset($a[$j]);
}
}
$items['x']['y'] = $a;
echo '<pre>', print_r($items, true), '</pre>';
The array with an ID of 390519 and a value of 85 should be removed. But that code does not work, it prints out the full array.
Any ideas how i can do this?
Thanks
