    <p>I want to print the output(i.e. value of variable $matter) but I'm getting the error message mentioned above. I did lot of google for it and checked for spaces before and after php tags. But couldn't get the solution. Please help me. Here is my code to print output using tcpdf: </p> <pre><code>&lt;?php ob_start(); require_once("../../includes/application-header.php"); // Include tcpdf liabrary require_once OCN_ROOT."/core/extention/tcpdf/config/lang/eng.php"; require_once OCN_ROOT."/core/extention/tcpdf/tcpdf.php"; define ('PDF_MARGIN_TOP', 22); define ('PDF_HEADER_TITLE', 'This is Heading'); define ('PDF_HEADER_STRING', $head_string); define ('PDF_CREATOR', PAGE_TITLE); // create new PDF document $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); // set document information $pdf-&gt;SetCreator(PDF_CREATOR); $pdf-&gt;SetAuthor(PDF_CREATOR); $pdf-&gt;SetTitle('TCPDF Example'); // set default header data $pdf-&gt;SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE, PDF_HEADER_STRING); // set header and footer fonts $pdf-&gt;setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN)); $pdf-&gt;setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA)); // set default monospaced font $pdf-&gt;SetDefaultMonospacedFont(PDF_FONT_MONOSPACED); //set margins $pdf-&gt;SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT); $pdf-&gt;SetHeaderMargin(PDF_MARGIN_HEADER); $pdf-&gt;SetFooterMargin(PDF_MARGIN_FOOTER); //set auto page breaks $pdf-&gt;SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM); //set image scale factor $pdf-&gt;setImageScale(PDF_IMAGE_SCALE_RATIO); //set some language-dependent strings $pdf-&gt;setLanguageArray($l); // --------------------------------------------------------- // set font $pdf-&gt;SetFont('helvetica', '', 10); // add a page $pdf-&gt;AddPage(); $matter = &lt;&lt;&lt;EOD &lt;h1&gt;HTML Example&lt;/h1&gt; EOD; $pdf-&gt;writeHTML($matter, true, false, true, false, ''); // reset pointer to the last page $pdf-&gt;lastPage(); // --------------------------------------------------------- ob_flush(); //Close and output PDF document $pdf-&gt;Output('example_061.pdf', 'I'); //============================================================+ // END OF FILE //============================================================+ ?&gt; </code></pre>

    1. COCheck if your script is saved as UTF-8 with a BOM. If so, save it without a BOM (it should be a setting in your editor). If this is the case, you will see `0xFF 0xEF` bytes output at the very top of the response. Do this for all scripts involved, including the ones you are `require()`ing and any scripts that they `include()`/`require()`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
