Reading rows of array from text file

[jch02140]

I am trying to print out rows of images and pieces them to form a bigger map but having a little trouble printing out correctly.

I am doing the following...

A numbered text file with rows of numbers like these:

33.txt

48,48,49,49,48,47,48,49,48,50,50,48,50,49,48,49,49,49
49,11,4,8,50,11,4,4,8,48,11,4,4,8,48,11,8,50
...

The number represent different area and the number in the text file represent each individual pieces of that particular area. the number of rows and columns are arbitrary.



Example:

Here is my code at the moment but there is something wrong in it as I can't seems to correctly print everything out...

<?php 
    $file = file_get_contents("33.txt"); // can be any numbered text files
    $entries = explode("\n", $file);
    echo "Entries <br /><hr />";

    for($i=0;$i < sizeof($entries);$i++){
        for($j=0;$j < sizeof($entries);$j++){
            $data = explode(",", $entries[$j]);    
              echo "<td align=\"center\" background=\"test/33_";
              echo $data[$j];
            echo ".gif\" width=\"65\" height=\"65\">
                <table border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"65\" height=\"65\">
                    <tbody><tr>
                        <td>
                            <center></center>
                        </td>
                    </tr></tbody>
                </table>
                </td>";
        }
    }
?>

Here's my shot at it, untested:

<?php 
    $file = file("33.txt"); // can be any numbered text files
    echo "<table border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"65\" height=\"65\"><tbody>";
       foreach($file as $line){
       echo "<tr>";
          $tiles=explode(",",$line);
          foreach($tiles as $piece){
          $image="test/33_".$piece.".gif";
          echo "<td><img src='".$image."' alt='' /></td>";
          }
       echo "</tr>";
       }
    echo "</tbody></table>";
?>

Start with the following code and modify it appropriately

$contents = @file("33.txt");
if (is_array($contents))
{
        foreach($contents as $row)
        {
                $ids = explode(",", $row);
                if (is_array($ids))
                {
                        foreach($ids as $id)
                        {
                                echo "<img src=\"test/33_" . trim($id) . ".gif\" alt=\"\" />\n";
                        }
                }
        }
}

Thanks for the help.

I managed to get it solve with the code samples above.

.... and GVRE is correct ... test to make sure the array is a valid array before you loop.

I was being sloppy.
