Slp to php graph8/13/2023 ![]() ![]() We may also want to style the header row ( ID, Season, etc). If fetchall is called without the option PDO::FETCH_ASSOC, the result set will actually contain two sets of identical data, one in associated array form, one in indexed form and will create duplicates in the Excel file when using fromArray. NOTE: When we use PDO to fetch the data, a simple $res = $q->fetchAll(\PDO::FETCH_ASSOC) call will force the returned result data set to contain an associated array only, without index. a cell reference to start the filling (from left to right, then up to down). ![]() a “filler” value in case the data is NULL ģ. $ews -> setCellValue ( 'a1', 'ID' ) // Sets cell 'a1' to value 'ID $ews -> setCellValue ( 'b1', 'Season' ). For structured data, most of which comes from an SQL select statement, we will use the fromArray method.For those headings, titles, other descriptive items, we will populate them one by one using setCellValue method.To populate a cell/cells, we have at least two options: The default name of this sheet is always “Worksheet” and we can change it with the setTitle method. So the 1st (and up to now the only) sheet will be Sheet Zero. The sheets in a workbook are always 0-indexed. To get the reference to a worksheet, we use: $ews = $ea -> getSheet ( 0 ) $ews -> setTitle ( 'Data' ) The worksheet is probably the object that we’ll manipulate the most: populating cells with data or formulas, applying styles, doing data filtering, inserting a chart, etc. There are some discrepancies in the mapping, but they are not too difficult for us to make the connection (e.g., “Authors” will be mapped to setCreator). The methods ( setXXXX) are quite self explanatory and map to the “Properties” dialog quite well. The properties shown in the above dialog will have corresponding setXXXX methods to set these properties, where XXXX is almost identical to the property names listed in the dialog: $ea -> getProperties ( ) -> setCreator ( 'Taylor Ren' ) -> setTitle ( 'PHPExcel Demo' ) -> setLastModifiedBy ( 'Taylor Ren' ) -> setDescription ( 'A demo to show how to use PHPExcel to manipulate an Excel file' ) -> setSubject ( 'PHP Excel manipulation' ) -> setKeywords ( 'excel php office phpexcel lakers' ) -> setCategory ( 'programming' ) The meta data is shown when we “Alt-Enter” an Excel file (or right click on that file and choose “Properties”): ![]() It has its own meta data to describe the file that we create. To instantiate an Excel file, we use: $ea = new \PHPExcel ( ) // ea is short for Excel ApplicationĪn Excel application instance usually is mapped to a physical Excel file. Other important terms may include: cell, range, etc. These are the two most important terms in Excel. The worksheet is the “canvas” we play with. Under normal circumstances, it will also contain a workbook with 3 (in Excel 2013, only 1) worksheets. When we click the icon to launch Excel, the Excel application starts. ![]()
