Question

Answer 1

+1 A:

You can remove duplicates from an array by doing:

$array = array_values(array_unique($array));

Does this work for multidimensional arrays? I don't think so...

Answer 2

+1 A:

Use the array_unique function.

Here is an implentation of a multi-dimensional array_unique 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;
}

Not tested, from the comments in the function manual.

I tried that, but it's still showing duplicates

+1, however that seems awfully familiar (http://stackoverflow.com/questions/1247950/how-to-remove-duplicated-2-dimension-array-in-php/1248189#1248189)... xP

You need to cast the objects to arrays and use `array_merge`.

Tried the code from the other thread but doesn't work with my array, it still comes up with duplicates..

Answer 3

+1 A:

Not a direct answer, but can´t you catch it at query level as it seems it´s coming from a database?

Something like GROUP BY bid...

jeroen 2010-05-18 21:41:26

I'm pulling the information from the database and splitting the single array into smaller arrays, but somehow it's getting duplicated, I'm guessing my array_split function is causing this..

SoulieBaby 2010-05-18 22:04:56

So then fix that code instead of putting a band aid on it. I hope you're not getting paid for this, and I hope never to have to maintain anything you write.

George Jempty 2010-05-18 22:14:26

I haven't seen your array_split function, but it seems to me you'd better fix that instead of patching things up afterwards.

jeroen 2010-05-18 22:16:14

George, bad day?

jeroen 2010-05-18 22:19:19

Actually the array_split function wasn't mine. I just have to deal with the consequences of that function, but thanks for your "enlightened" comment George.

Answer 4

A:

My PHP's rusty, but something like this should work:

function makeUniqueBidArray(&$array)
{
  $tempArray = array();
  foreach($array as $bidArray) {
    foreach($bidArray as $bid) {
      if (isset($tempArray[$bid->bid]) {
        unset($bid);
      } else {
        $tempArray[$bid->bid] = $bid->name;
      }
    }
  }
}

Answer 5

A:

stop using your own array splitting function that causes duplicates and read the php manual page on array_chunk
