Right now when I use a cell with text, it all stays on one line. I know I could use the write function, but I want to be able to specify the height and width.
This is what I have now, but as I said the text does not wrap to stay in the dimensions:
$pdf->Cell( 200, 40, $reportSubtitle, 1, 1 );
MultiCell is used for print text with multiple lines. It has the same atributes of
Cell except for
$pdf->MultiCell( 200, 40, $reportSubtitle, 1);
What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).
MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])
