  1. I have trouble in modifying PHPExcel library. I have search through Google and search option here. But i cannot found the solution. I have successful in export all the column from my table into Excel. But the problem now is I want export only selected column to Excel file. Example : I have 3 checkbox (A,B,C) equivalent with column (A,B,C) from my database table . I want to export only column A so that I check only checkbox A. If I want export column B & C then I will check the checkbox B & C. I hope you guys can help me with this. Thank you !

  3. Hi guys, Im trying to make a webscrapper and im having a huge problem when retrieving huge amount of data. I have tried to increase the memory through PHP.ini but its still doesnt solve the problem. The webscrapper I want to make is to retrieve data from database journal and put it into an excel file. While it is working with small datasets, it will run out of memory when retrieving large datasets. Here is the code : x <?php function fetchRawData($url,$search,$currentpagenumber,$numpage,$numrecordtotalsofar) { if($currentpagenumber<$numpage) { //initialise curl $url = "http://ieeexplore.ieee.org/search/searchresult.jsp?queryText%3D".$search."&rowsPerPage=100&pageNumber=".$currentpagenumber."&resultAction=ROWS_PER_PAGE"; echo "<br>new url = ".$url."<br>"; $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,true); curl_setopt($ch,CURLOPT_FAILONERROR,true); curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true); // curl_setopt($ch,CURLOPT_TIMEOUT,50000); curl_setopt($ch,156,500000000); curl_setopt($ch,155,500000000); curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false); curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false); $data=curl_exec($ch); if(!$data) { var_dump(curl_getinfo($ch)); die(); } //parsing data $parsedData = array(); phpQuery::newDocumentHTML($data); $arrtitle = array(); $posttitle=1; if($currentpagenumber<2) { $numrecordsofar=1; } else { $numrecordsofar=$numrecordtotalsofar; } //get the title, author and year of publication foreach(pq("a") as $link) { $title = pq($link)->text(); if($title) { //use regular expression to get the relevant information if (preg_match("*articleDetails.jsp*", pq($link)->attr('href'))&&$gettitle<1) { if(!(preg_match("*View full abstract*", $title))) { $dummyvar=$numrecordsofar+$posttitle; array_push($arrtitle,$title); $countrecord++; $gettitle=1; } } } } //get the number of data foreach(pq("span") as $link) { $title = pq($link)->text(); if($title) { if (preg_match("*display-status results-returned*", pq($link)->attr('class'))) { $countnumberonly = preg_replace("*Results returned*", "", $title); $totalpageint = intval($countnumberonly); //calculate how many pages needed and record the current page $totalpageint = intval($totalpageint / 100)+2; } } } //initialise write to excel $objPHPExcel = new PHPExcel(); $objPHPExcel->getProperties()->setCreator("Maarten Balliauw") ->setLastModifiedBy("Maarten Balliauw") ->setTitle("PHPExcel Test Document") ->setSubject("PHPExcel Test Document") ->setDescription("Test document for PHPExcel, generated using PHP classes.") ->setKeywords("office PHPExcel php") ->setCategory("Test result file"); // Set active sheet index to the first sheet, so Excel opens this as the first sheet $objPHPExcel = PHPExcel_IOFactory::load("IEEE_Scrap.xlsx"); $objPHPExcel->setActiveSheetIndex(0); $objPHPExcel->createSheet(); $row = $objPHPExcel->getActiveSheet()->getHighestRow()+1; //get data from arrays for($j=0;$j<count($arrtitle);$j++) { if(isset($arrtitle[$j])) { $dummyvar=$numrecordsofar+$j; $objPHPExcel->getActiveSheet()->SetCellValue('A'.$dummyvar,$arrtitle[$j]); } else { $dummyvar=$numrecordsofar+$j; $globalIEEE[$tempcount+$j][0]="No Data"; $objPHPExcel->getActiveSheet()->SetCellValue('A'.$dummyvar,"No Data"); } } $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel); $objWriter->save('IEEE_Scrap.xlsx'); //close curl and phpexcel curl_close($ch); unset($ch); unset($objPHPExcel); unset($objWriter); $currentpagenumber++; $numrecordtotalsofar=$numrecordtotalsofar+$countrecord; set_time_limit(0); sleep(5); $rawHTML = fetchRawData($url,$search,$currentpagenumber,$totalpageint,$numrecordtotalsofar); return $data; } } ?> The logic is first I retrieve the data on a page then putting it into an array after parsing it then initalise phpexcel to write the data from the array into excel then unset cURL and phpexcel and then move on to next page. Sorry the code is a bit messy as I have tried so many modifications but still cant get it work. Please help me !
  4. Hello PhpFreaks! I'm trying to use Phpexcel to extract data from one excel sheet to be able to write it to a template excel sheet. But I can't seem to get the entire thing working. For example; taking the value of the cell "C4" in the excel Spreadsheet "Firstsheet.xls". And to write it to a new excel sheet, "Template.xls" in the cell "D2". I'm currently trying to use this: $objPHPExcel = PHPExcel_IOFactory::load("FirstSheet.xls"); $objPHPExcel2 = PHPExcel_IOFactory::load("Template.xls"); $objPHPExcel2->getActiveSheet()->setCellValue('D2',$objPHPExcel->getActiveSheet()->GetCell('C4')->getValue()); However, opening up two sources at the same time is seen as "bad coding"; a possible solution might be to either to open up the first excel sheet and store it to a multiple dimension array, close it. Then to open up the second sheet and access the data of the first sheet from the array. But I'm not really sure how to do so. -- This is my code so far, that needs fixing: Thanks, Nell
