Adding to an array

[treeleaf20]

I have the following code:

if (empty($zips)) echo 'Error: '.$z->last_error;
else {
   foreach ($zips as $key => $value) {
      echo "Zip code <b>$key</b> is <b>$value</b> miles away from <b>93001</b>.<br>";
	  $getcity = "Select city from zip_code where zip_code = '$key'";
	  $resultgetcity = mysql_query($getcity);
	  $resultsetgetcity = mysql_fetch_array($resultgetcity);
}

I want to add every result to an array because I need to manipulate it later. I tried to do something like this:

if (empty($zips)) echo 'Error: '.$z->last_error;
else {
   foreach ($zips as $key => $value) {
      echo "Zip code <b>$key</b> is <b>$value</b> miles away from <b>93001</b>.<br>";
	  $getcity = "Select city from zip_code where zip_code = '$key'";
	  $resultgetcity = mysql_query($getcity);
	  $resultsetgetcity = mysql_fetch_array($resultgetcity);

  $orgcity = "Bigcity";
  $cities = array($orgcity);
  array_push($cities, $resultsetgetcity[0]);
}

I was hoping that I could run a while loop or a for loop and loop through all of the contents of $cities but I can't seem to add every result to the array from the foreach statement. Can anyone help me?

Thanks in advance.

Not sure what this code is supposed to do

$orgcity = "Bigcity";
      $cities = array($orgcity);
      array_push($cities, $resultsetgetcity[0]); 

try instead

      $cities[]= $resultsetgetcity[0]);

What would the for loop look like to loop through all of the results in the array? I would to use a for loop because I would like to do some other things in the loop like keep a count using a $count variable. I tried to do this:

   foreach($cities as $key=>$value)
    {
	echo "$key : The city is $value<br>";
	$count = "0";
	$count++;
	echo "$count<br>";
    }

That only ever gets to one, I could use the $key variable but I want to reset the $count variable after 3 or 4 itterations of the the loop to 0 again. If this can be done using the foreach I would be fine using that.

Thanks for the continued help

$count only ever gets to 1 because you set it to 0

$count = "0";

then add 1:
$count++;

every time!

$loopcounter=0;
foreach ($cities as $city){
    echo "The city name is $city...";
    $loopcounter++;
    if($loopcounter==4){
        //do something
        echo "This is city 5!...";
        //reset counter
       $loopcounter=0;
    }
}//end for loop

Is their a function or a way to determine if an element is in the array more then once. So for example if I had an array like this:

$array = array("Test", "Test", "Site", "Web")

For this example I would like to output only one of each. So I would like the output to be:
Test
Site
Web

So basically I'm trying to eliminate duplicates from the array and only display the name once even if there are multiple instances of it in the array.

Thanks for the continued help.
