php - why can't I overlay text on the bottom part of the page using fpdfi? -


background: i'm developing application involves taking existing pdf form , overlaying text on top of it. pdf version 1.3. i'm using fpdfi class (written in php) can found here:

http://www.setasign.de/support/manuals/fpdi/

i using fpdfi extension of tcpdf class found here:

http://www.tcpdf.org/index.php

i use line of (php) code looks this:

$this->setxy(25, 250);$this->cell(0, 8.6, $data['my_data_to_overlay']);

where $this refers instance of fpdfi class, setxy function tells coordinates wish place text (x,y), , cell function tells text want displayed , how large , such. page height 279.4 (all units here in mm)

the problem:

if set y coordinate higher 250 (even @ 251), text placed on next page instead of near bottom of current page expected. other coordinates above line @ 250 display properly, @ top edge of page.

why can not overlay text near bottom of page? doing wrong?

also of note: margins page set 0 , headers , footers disabled.

disable auto page break calling fpdf::setautopagebreak false, or true 0 margin.

edit: using fpdf::setmargins can set left, top , right margins, not bottom one. proper way specify bottom margin.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
