Write a PHP program to print alphabet pattern 'X'

<?php
for ($row=0; $row<7; $row++)
{
  for ($column=0; $column<=7; $column++)
	{
       if ((($column == 1 or $column == 5) and ($row > 4 or $row < 2)) or $row == $column and $column > 0 and $column < 6 or ($column == 2 and $row == 4) or ($column == 4 and $row == 2))
            echo "*";    
        else  
            echo " ";     
	}        
  echo "\n";
}
?>

Sample Output:

 *   *                                                      
 *   *                                                      
  * *                                                       
   *                                                        
  * *                                                       
 *   *
