Previous Comments: ------------------------------------------------------------------------ [2005-10-12 12:11:12] dolecek at stringdata dot cz No, I've only tried PHP 5.1rc1 and 5.0.5 - is there any related change to php_formatted_print() et.al recently which might likely fix this? ------------------------------------------------------------------------ [2005-10-12 12:08:44] tony2001@php.net Have you tried the snapshot? ------------------------------------------------------------------------ [2005-10-12 12:07:00] dolecek at stringdata dot cz Reproduce steps: 1. download FPDF 1.53 (fpdf153.zip), extract to suitable directory accessible via web server 2. edit fpdf.php and replace line: $this->_out('/CreationDate '.$this->_textstring('D:'.date('YmdHis'))); with: $this->_out('/CreationDate '.$this->_textstring('D:20051011143910')); This is necessary so that generated PDF don't differ gratuitously. 2. put attached script to the same directory as the modified fpdf.php 3. run: siege -c 10 -v -u http://server/path/to/script.php The script: $pdf=new FPDF(); $pdf->AddPage(); $pdf->SetFont('Arial','B',16); $pdf->Cell(40,10,'Hello World!'); $pdf->SetFont('Arial','',10); $pdf->Cell(60,10,'Powered by FPDF.',0,1,'C'); $content = $pdf->Output(false, 'S'); if (md5($content) != '38ec5b17d2cda871e21b28ecaeecd08d') { trigger_error('pdf generation test bug', E_USER_ERROR); } ------------------------------------------------------------------------ [2005-10-11 17:38:52] tony2001@php.net Please try using this CVS snapshot: http://snaps.php.net/php5-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.0-win32-latest.zip And try snapshot first. ------------------------------------------------------------------------ [2005-10-11 17:38:24] tony2001@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
