Look for duplicate values in a associative array and add them to a count

Question

Hi I am trying to count the number of duplicate values in a associative array that looks like this:

array(3) { [0]=> array(3) { [\"Title\"]=> string(25) \"

Okey so I found my solution and I made it look something like this probably not he most efficient way but it works:

$prodArray = array();
$ar = array();


$query ="THE QUERY";
$result = mysql_query($query) or die(mysql_error());

while($row = mysql_fetch_array($result))
{
array_push($ar, $row['prodTitle']);
}

function findDuplicates($data,$dupval) {
$nb= 0;
foreach($data as $key => $val)
if ($val==$dupval) $nb++;
return $nb;
}


$uniarr = array_unique($ar);

//Will run the function findDuplicates for each unique title in the array
for ($i = 0; $i < sizeof($uniarr); $i++)
{
$count = findDuplicates($ar, $uniarr[$i]);
array_push($prodArray, array( Title => $uniarr[$i], Count => $count));
}

//Displays 2 of the results in the array
for ($c = 0; $c < 2; $c++)
{
echo "The title:".$prodArray[$c]["Title"]." And the amount:".$prodArray[$c]["Count"];
echo "
";
}

So that's pretty much it feel free to post your comments on this and if you have any improvements feel free to post them.
