PHPExcel - How to make part of the text bold
How do you create a bold cell value using PHPExcel? I know I can use \n to add a carriage return within the text, but is there some kind of way to bold part of cell value? I also have tried using html formatting such as <b> or <strong> but it did not work.
Answer
You can bold part of the text in a cell using rich text formatting, as described in section 4.6.37 of the developer documentation.
$objRichText = new PHPExcel_RichText();
$objRichText->createText('This text is ');
$objBold = $objRichText->createTextRun('bold');
$objBold->getFont()->setBold(true);
$objRichText->createText(' within the cell.');
$objPHPExcel->getActiveSheet()->getCell('A18')->setValue($objRichText);
