Import an Excel file

/** * Import Excel File * @param  string $file Excel file path * @return        array of contents of Excel file */function Import_excel ($file) {    / /Determine what format the file is    $type = PathInfo ($file);    $type = Strtolower ($type ["extension"]);    $type = $type = = = ' csv '? $type: ' Excel5 ';    Ini_set (' max_execution_time ', ' 0 ');    Loader::import (' Phpexcel.phpexcel ');     Determine which format to use    $objReader = Phpexcel_iofactory::createreader ($type);    $objPHPExcel = $objReader->load ($file);    $sheet = $objPHPExcel->getsheet (0);    Total number of rows obtained    $highestRow = $sheet->gethighestrow ();    Total number of columns obtained    $highestColumn = $sheet->gethighestcolumn ();     Iterate through the Excel file, read a line, insert a    $data =array ();    Reads data from the first line for    ($j =1; $j <= $highestRow; $j + +) {        //reads data from column A for        ($k = ' a '; $k <= $highestColumn; $k + +) {            //Read cell            $data [$j][]= $objPHPExcel->getactivesheet ()->getcell ("$k $j")->getvalue ();}    }    return $data;}

Array to XLS format Excel file

/** * Array to XLS format for Excel file * @param array $data need to generate arrays of Excel files * @param string $filename generated Excel file name * Sample data: $data = Array (NULL, all, (), Array (' Q1 ', ","), Array (' Q 2 ', ",", ","), Array (' Q3 ', ","), Array (' Q4 ', 30, 32, 0),);    */function Create_xls ($data, $filename = ' Simple.xls ') {ini_set (' max_execution_time ', ' 0 ');    Loader::import (' Phpexcel.phpexcel '); $filename =str_replace ('. xls ', ', $filename).

"    \t\r\n "; }}

Examples of Use:

Import principle:

The file to be imported is first uploaded to the server via the Thinkphp method, then the public import method is invoked according to the uploaded path, and the file path of Excel to be imported is as follows

Public Function Importuser () {        $data =import_excel ('./a.xls ');        Print_r ($data);        Exit;    }
