The first chart we are to create is a line chart showing the ups and downs of the scores in each game of the Lakers team and its opponent.Ĭreating a chart is a lengthy coding job, even with the support of a library.By Avantix Learning Team | Updated March 24, 2021Īpplies to: Microsoft ® Excel ® 2013, 2016, 2019 and 365 (Windows) PHPExcel can tap into almost all of these. Excel has a rich set of built-in charts for us to choose from. It is always nice to have a visual representation of our data, so the chart will come in handy. This means auto width calculation will not always work. The result is that this cell ( A1) is still squeezed. But, the setAutoSize method fails on this merged cell. The merging of A1 and B1 into A1 is also done correctly. The result shows that the font weight, font size, and alignment are correctly applied. For A1, I have applied the following style: $ews2 -> setCellValue ( 'a1', 'Lakers 2013-2014 Season' ) $style = array ( 'font' => array ( 'bold' => true, 'size' => 20, ), 'alignment' => array ( 'horizontal' => \PHPExcel_Style_Alignment :: HORIZONTAL_LEFT, ), ) $ews2 -> mergeCells ( 'a1:b1' ) $ews2 -> getStyle ( 'a1' ) -> applyFromArray ( $style ) $ews2 -> getColumnDimension ( 'a' ) -> setAutoSize ( true ) The % shown in cell B4 is set by the following code: $ews -> getStyle ( 'b4' ) -> getNumberFormat ( ) -> setFormatCode ( \PHPExcel_Style_NumberFormat :: FORMAT_PERCENTAGE ) If there is a chart, the G:G notation will fail, throwing an exception. This works fine when there is NO chart in the sheet. A lazy way of writing that formula is to use a range like G:G. NOTE: Please pay special attention to the cell reference ( G2:G91). The formula string is just like the one we will input in an Excel file to perform the necessary calculation. You see, it is no different from what we have done in the previous section. With the worksheet inserted, we can populate the cells in this worksheet as usual and apply styles. $location: the index of this worksheet.$ews2: the Excel worksheet instance that we are to insert.The addSheet method takes two parameters. To insert a new worksheet, we do: $ews2 = new \PHPExcel_Worksheet ( $ea, 'Summary' ) $ea -> addSheet ( $ews2, 0 ) $ews2 -> setTitle ( 'Summary' ) I always use a separate sheet to store the original data and at least one more sheet to display the summary and/or analytic information. If we save the file now – we will discuss saving later – we will see that the XLSX file is filled with the data and properly formatted:Īdding another sheet and inserting formulas Unfortunately, this does not support a range parameter, so we use a for loop to make this happen. There will be two routes defined: $app -> get ( '/', function ( ) use ( $app ) Index.php will be the entry point for our Silex application. Make sure the necessary dependencies are correctly specified in your composer.json file. Twig will be used as the template engine. The data is retrieved with a simple SQL statement: “ select * from lakers” (total 90 records, including 8 pre-season and 82 regular season games).Īlso, this demo uses Silex as the MVC framework. The data dump for this tutorial ( lakers.sql) has been uploaded to the repo associated with this article. Of course, we should have our database up and running. There are also 3 PHP extensions to be enabled: php_zip (which is essential to operate Office 2007 formats), php_xml and php_gd2 (optional, but required for exact column width auto-calculation). To use PHPExcel, we must have PHP version above 5.2.0. That Excel file will be populated with some additional analytic data and a chart also generated by PHP and Excel.A button that will export the data into an Excel 2013 file.A sheet showing the game information (date played, teams, score, win/lose status) of my favorite NBA team – LA Lakers, in its 2013-14 season.The lib we use here is called PHPExcel, a subset of PHPOffice, which can be cloned here. NOTE: There are a few PHP libraries that can provide Excel (and Office) file manipulations.

In this article, we will see how to use a PHPExcel library to provide an “Export to Excel” function in a web app so that the user can export the data into an Excel 2007/2013 file for further analysis. After my article “ How To Make Microsoft Word Documents with PHP” (using Interop capability under Windows), there were quite a few comments urging a pure PHP implementation, i.e., only using a universal PHP library to manipulate Office files.
