[Resolved] problem with array_unique

[johnskywalker99]

Hello, I have an array:

$DuplicateArray =
pftest6[1]
pftest5[2]
pftest4[3]
pftest3[4]
pftest2[5]
pftest6[6]
pftest5[7]
pftest4[8]
pftest3[9]
pftest2[10]
pftest1[11]
pftest1[12]

and when I pass it to array_unique it drops one of the duplicated values.

$UniqueArray = array_unique($DuplicateArray);

for ($x=0; $x<=count($UniqueArray); $x++) {
echo "$UniqueArray[$x]<br>";
}

Outputs:

pftest6
pftest5
pftest4
pftest3
pftest2

So its dropping 'pftest1' can anyone tell me why? I've even tried extending the count manually to include [0] & [6] but there still blank, many thanks in advance

array_unique() preserves the keys, so you should either use a foreach loop, or assign the result array_values() on the unique array to a new unique array with re-ordered keys.

Thanks for that - the for each loop worked a treat - your a star!
