$tiles["02,01"] = "";
$tiles["03,01"] = "";


function draw_game()
{
echo "<table border=\"0\" width=\"500\" height=\"500\" />";
//for each of the tiles execute the code
print_r($tiles);

	foreach( $tiles as $id => $tile)
	{
	//add start of table row tag if count is equal to 10,20,30
	if ($count == 0 || $count == 10 || $count == 20 || $count == 30)
		{
			echo "<tr>";
		}

			echo "<td width=\"50\" height=\"50\" alight=\"left\" />";

		//check what tile image to output, default is grass	
			switch($id)
			{
				case 1:
				echo "<img src=\"$id.gif\" alt=\"$tile\" />";
				break;

				default:
				echo "<img src=\"grass.gif\" alt=\"$tile\" />";

			}

			echo "</td>";
		//add end of table row tag if count is equal to 10,20,30
		if ($count == 0 || $count == 10 || $count == 20 || $count == 30)
			{
				echo "<tr>";
			}

$count++;
	}

echo "</table>";


}

Hi

 

The array is declared outside the function. Unless you have it declared as global within the function or passed to the function then nothing inside the function knows about it.

 

All the best

Thanks again,

you set the $tiles outside the function and try to use it into a function?

functions using only local vars (into the function) or you just make it global var...

 

<?php

//Test Array
$tiles = array();
$tiles["01,01"] = "";
$tiles["02,01"] = "";
$tiles["03,01"] = "";

function draw_game()
   {

   global $tiles;

   echo "<table border="0" width="500" height="500" />";
   //for each of the tiles execute the code
   print_r($tiles);
   
      foreach( $tiles as $id => $tile)
      {
      //add start of table row tag if count is equal to 10,20,30
      if ($count == 0 || $count == 10 || $count == 20 || $count == 30)
         {
            echo "<tr>";
         }
         
            echo "<td width="50" height="50" alight="left" />";
         
         //check what tile image to output, default is grass   
            switch($id)
            {
               case 1:
               echo "<img src="$id.gif" alt="$tile" />";
               break;
               
               default:
               echo "<img src="grass.gif" alt="$tile" />";
               
            }
            
            echo "</td>";
         //add end of table row tag if count is equal to 10,20,30
         if ($count == 0 || $count == 10 || $count == 20 || $count == 30)
            {
               echo "<tr>";
            }
         
   $count++;
      }
      
   echo "</table>";
   
      
   }
