You can use PDF_info_textline to center some text in the page.





Here's a little function





<?php


// Parameters:


// $p -> the PDF handle


// $text -> the text to center


// $posy -> the vertical position of the text


// $pageWidth -> the width of the page, defaults to 595 (A4)


function center_text($p, $text, $posy, $pageWidth=595)


    {


    $width = PDF_info_textline($p, $text, 'width', '');


    PDF_fit_textline($p, $text, ($pageWidth-$width)/2, $posy, '');


}


?>
