Display 2D Array as HTML Table in PHP

You can display a 2 dimensional array in PHP as a HTML table using nested foreach loop. For example, this is useful when you get rows of information from MySQL, and then you need to display its output as a table.

The function uses two foreach loops. The first or outer loop gets one row at a time. The second loop or inner loop gets columns from the row as table data.

public function displayTable()
{
 $disp = '<table class="table">';
 foreach ($this->rows as $tr) 
 {
 $disp .= '<tr>';
 foreach ($tr as $td)
 {
 $disp .= '<td>' . $td . '</td>';
 }
 $disp .= '</tr>';
 }
 $disp .= '</table>';
 echo $disp;
}
