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, '');

}

?>
