					"tile","tile","tile","tile",
					"tile","tile","tile","tile"
					);
	echo $array[0][1];
	
	for($c=0;$c<$cols;$c++){
		$x=$c*40;
		if($black==false){
		echo "<spam style='
					left:$x;

What is that code? It`s a mess currently. Try doing in small steps. You want something with colors, but it`s not working correct?

Anyway, you have an X axis and an Y axis. So rows == y and cols == x.

So in order for the grid to display, you have to go trough all Y, in each Y ( as long as Y <= $rows ) go trough each X as X <= $cols.

So :

Code: Select all

for($y = 0; $y <= $cols; $y ++ ){
      for($x = 0; $x <= $rows ; $x ++ )
      { 
           // print a block
      }
}

Code: Select all

<?php
error_reporting(E_ALL);
ini_set("display_errors", true);

       $rows = 3;
       $cols = 4;

       $black = false;
       $white = false;

       $width = 20;
       $height = 20;


       $text[5][5] = array(
                   "tile","tile","tile","tile",
                   "tile","tile","tile","tile",
                   "tile","tile","tile","tile",
                   "tile","tile","tile","tile"
                   );

       echo "<div style='width:300px; height: 500px;'>
             ";
       for($yt = 0; $yt <= $cols ; $yt++ )
       {
             echo '<div style="height: 60px; margin: 10px; background-color: red; width: 100%;">
                   ';
            for($xt = 0 ; $xt <= $rows ; $xt++ )
            {
                  echo '
                        <div style="float: left; font-size: 11px; color: white; width: 50px; height: 40px; margin: 10px; background: green;">
                              Y = '.$yt.' <br/> X = '.$xt.'
                        </div>
                  ';
            }
            echo "
                  </div>";
       }

       echo "
             </div>";

?>
