[Resolved] Need help combining arrays

TheDefender

OK, I have one array called headers, and one called data...

$headers = array("City", "State", "Zip");
$data = array("St. Petersburg", "FL", "33703");

// What I want is this:
$combined = array("City" => "St. Petersburg", "State" => "FL", "Zip" => "33703");

I am trying to find a function that will combine the arrays using the $headers array as the keys and the $data array as the values.

I found array_combine() in the php manual, but it is for PHP5 CVS only. Is there an existing function in PHP4, or has anyone written a function to do this in PHP4?

I would think someone has, but I can't wrap my brain around it.

Thanks for your help in advance.

Just a for loop would do it. You'd just have to add some checking.

if(count($headers) != count($data)) {
   echo "Counts do not match";
}
else {
   $combined = array();
   for($i=0;$i<count($data);$i++) {
      $combined[$headers[$i]] = $data[$i];
   }
}

I found this function on PHP.net posted by unluckypixie. What s/he had was

$arr1 = array("a"=>"1", "b"=>"2");
$arr2 = array("a"=>"one", "b"=>"two");
$arr = array("1"=>"one", "2"=>"two"); //Wanted to combine them into this

This was the solution s/he came up with:

foreach($arr2 as $key=>$value)
{
   if(isset($arr1[$key])) 
   {
       $result[$arr1[$key]] = $value;
   }
}

Hope this helps 😉

Thanks guys. I figured I would just have to do the FOR loop. I guess I was just being lazy... LOL.

Now, I have to figure out why my array counts aren't the same... I think I have a rogue space in there somewhere that isn't being exploded properly... Thanks again guys.
