array won't return out of function

[aconway]

I'm lost... as most of you know

I have a function that puts values in an array. I can print the values in the function, but I can't get the array out of the function.

I've tried:
return $array; - from inside the function
and
global $array; - from outside the function

am I forgeting some other way of getting it?

Hi,

Note: This might be a stupid question, but here goes...
Do you fetch the returned array in a variable?

function foo()
{
  // fill the array with values
  return $array;
}

$arr = foo();

Yours, Erik.

Post some of your applicable code, so we know what your array looks like, and how you are using it.

function get_animals($code,$animal)
{
   db_connect('pets');
   function chk($code,$table,$animal)
   {
      $results = mysql_query("SELECT * FROM $table WHERE code = '$code'");
      if ( mysql_num_rows($results) == 1 || $table == $animal) { return "checked"; }
   }

   $result = mysql_query("query");
   while ( $row = mysql_fetch_row($result) )
   {
      echo "<input type='checkbox' name='pets[]' value='$row[0]' ".chk($code,$row[0],$animal)."/>".$row[0]."<br/>\n";
      if (chk($code,$row[0],$animal) != '')
      {
      $all_animals[] = $row[0];
      }
   }
   return ($all_animals);
}

Dont declare functions embedded within other functions.
In this case, you can just manually make chk() inline.
Dont evaluate a function with the exact same parameters and state more than once.

A possible solution might be:

function get_animals($code,$animal)
{
	db_connect('pets');
	$all_animals = array(); //in case array is never actually initialised otherwise
	$result = mysql_query("query");
	while ( $row = mysql_fetch_row($result) )
	{
		$temp = mysql_query("SELECT * FROM {$row[0]} WHERE code = '$code'");
		if (mysql_num_rows($temp) == 1 || $row[0] == $animal)
		{
			$chk = "checked";
		}
		else
		{
			$chk = "";
		}
		echo "<input type='checkbox' name='pets[]' value='$row[0]' ".$chk."/>".$row[0]."<br/>\n";
		if ($chk == "checked")
		{
			$all_animals[] = $row[0];
		}
	}
	return $all_animals;
}

Thanks for the advice laserlight, but I still can't get the array $all_animals out of the function.

any other ideas? :bemused:
