You can also create new uni dimensional array
with key like this '0-1' and run array_unique
and after come back to myarray
for example
[UNTESTED]
foreach ($myarray as $key1 => $value)
foreach($value as $key2 => $value2) $new_array["$key1-$key2"] = $value2
;
unset($myarray) ;
$new_array = array_unique($new_array) ;
foreach($new_array as $key => $value)
if (ereg("([0-9])-([0-9])", $key, $reg) $myarray[$reg[1]][$reg[2]] = $value
;

Subject: [PHP] Removing duplicates in multi-dimensional array
I'm finding this one hard to approach...
I have a two-dimensional array, containing customer contact
information. Looks like:
$myarray[0][0] = "Microsoft";
$myarray[0][1] = "Bill";
$myarray[0][2] = "123-1234";
$myarray[1][0] = "Apple";
$myarray[1][1] = "Steve";
$myarray[1][2] = "456-1234"; <
$myarray[2][0] = "Oracle";
$myarray[2][1] = "Larry";
$myarray[2][2] = "987-4321";
$myarray[3][0] = "Pixar";
$myarray[3][1] = "Steve";
$myarray[3][2] = "456-1234"; <
What I want to do is remove records that have the same fax number, so
that each fax number occurs only once. For example, $myarray[1][2] and
$myarray[3][2] are the same--I would like to remove/unset one of them.
I know that array_unique() will do this for one-dimensional arrays, but
I'm kinda stuck here, since the repeating element is in the second
dimension. Any ideas how I might do this?
Thanks.
...Rene
