I would like to remove duplicate array values, and I
presume that array_unique should do this, but the
results are not what I am expecting
Anyone see this before:
$dayarray=(9,22,22);
$duparray = array_unique($dayarray);
$darray = count($duparray);
for($d=0;$d<$darray;$d++){
echo "$d: ".$duparray[$d]."<br>";
}
## returns:
0: 9
1:
rather than
0: 9
1: 22
Is that what it is supposed to do? Does array_unique
remove all instances of duplicate values?
If so, is there a way to remove every instance but the
first?
Thanks,
gr
