[SOLVED] array_unique()

[php_novice2007]

Hi, I'm trying to use the array_unique function and its not giving me some of my values...

 

So for example,

 

$input = array("4", "4", "3", "4", "3", "5","7","7");

$indiGroup = array_unique($input);

 

for($j=0; $j < count($indiGroup); $j++) {

      print "<option value=$indiGroup[$j]>$indiGroup[$j]</option>";

}

 

When I put this code in my page, my drop down lists has "4", and then a gap, and then "3", and then a gap.. It seems to be missing every second one.

 

???

print_r() the $indiGroup?

replace

for($j=0; $j < count($indiGroup); $j++) {
      print "<option value=$indiGroup[$j]>$indiGroup[$j]</option>";
}

with

foreach($indiGroup as $val){ echo"<option = $val> $val </option>";}

Sweet, thanks~!

 

I'm curious... How come the other way didn't work?

I don't believe you can use variables for array indexes inside of double quotes... you probably could have done...

print "<option value=" . $indiGroup[$j] . ">" . $indiGroup[$j] . "</option>";

with no problems
