How to use phpexcel to read data and insert into database?
In order to read data from microsoft excel 2007 by codeigniter just create a helper function excel_helper.php and add the following in:
require_once APPPATH.'libraries/phpexcel/PHPExcel.php';
require_once APPPATH.'libraries/phpexcel/PHPExcel/IOFactory.php';
in controller add the following code to read spread sheet by active sheet
//initialize php excel first
ob_end_clean();
//define cachemethod
$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;
$cacheSettings = array('memoryCacheSize' => '20MB');
//set php excel settings
PHPExcel_Settings::setCacheStorageMethod(
$cacheMethod,$cacheSettings
);
$arrayLabel = array("A","B","C","D","E");
//=== set object reader
$objectReader = PHPExcel_IOFactory::createReader('Excel2007');
$objectReader->setReadDataOnly(true);
$objPHPExcel = $objectReader->load("./forms/test.xlsx");
$objWorksheet = $objPHPExcel->setActiveSheetIndexbyName('Sheet1');
$starting = 1;
$end = 3;
for($i = $starting;$i<=$end; $i++)
{
for($j=0;$j<count($arrayLabel);$j++)
{
//== display each cell value
echo $objWorksheet->getCell($arrayLabel[$j].$i)->getValue();
}
}
//or dump data
$sheetData = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
var_dump($sheetData);

$this->benchmark->mark('code_start');
//=== change php ini limits. =====
$cacheMethod = PHPExcel_CachedObjectStorageFactory:: cache_to_phpTemp;
$cacheSettings = array( ' memoryCacheSize ' => '50MB');
PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings);
//==== create excel object of reader
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
//$objReader->setReadDataOnly(true);
//==== load forms tashkil where the file exists
$objPHPExcel = $objReader->load("./forms/5000records.xlsx");
//==== set active sheet to read data
$worksheet = $objPHPExcel->setActiveSheetIndexbyName('Sheet1');
$highestRow = $worksheet->getHighestRow(); // e.g. 10
$highestColumn = $worksheet->getHighestColumn(); // e.g 'F'
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
$nrColumns = ord($highestColumn) - 64;
$worksheetTitle = $worksheet->getTitle();
echo "<br>The worksheet ".$worksheetTitle." has ";
echo $nrColumns . ' columns (A-' . $highestColumn . ') ';
echo ' and ' . $highestRow . ' row.';
echo '<br>Data: <table border="1"><tr>';
//----- loop from all rows -----
for ($row = 1; $row <= $highestRow; ++ $row)
{
echo '<tr>';
echo "<td>".$row."</td>";
//--- read each excel column for each row ----
for ($col = 0; $col < $highestColumnIndex; ++ $col)
{
if($row == 1)
{
// show column name with the title
//----- get value ----
$cell = $worksheet->getCellByColumnAndRow($col, $row);
$val = $cell->getValue();
//$dataType = PHPExcel_Cell_DataType::dataTypeForValue($val);
echo '<td>' . $val ."(".$row." X ".$col.")".'</td>';
}
else
{
if($col == 9)
{
//----- get value ----
$cell = $worksheet->getCellByColumnAndRow($col, $row);
$val = $cell->getValue();
//$dataType = PHPExcel_Cell_DataType::dataTypeForValue($val);
echo '<td>zone ' . $val .'</td>';
}

}
else

$val = $cell->getValue();

Using the PHPExcel library, the following code will do.
require_once dirname(__FILE__) . '/../Classes/PHPExcel/IOFactory.php';
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setReadDataOnly(true); //optional
$objPHPExcel = $objReader->load(__DIR__.'/YourExcelFile.xlsx');
$objWorksheet = $objPHPExcel->getActiveSheet();
$i=1;
foreach ($objWorksheet->getRowIterator() as $row) {
$column_A_Value = $objPHPExcel->getActiveSheet()->getCell("A$i")->getValue();//column A
//you can add your own columns B, C, D etc.
//inset $column_A_Value value in DB query here
$i++;
}
Using the PHPExcel library to read an Excel file and transfer the data into a database
// Include PHPExcel_IOFactory
include 'PHPExcel/IOFactory.php';
$inputFileName = './sampleData/example1.xls';
// Read your Excel workbook
try {
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);
} catch(Exception $e) {
die('Error loading file "'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage());
}
// Get worksheet dimensions
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
// Loop through each row of the worksheet in turn
for ($row = 1; $row <= $highestRow; $row++){
// Read a row of data into an array
$rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row,
NULL,
TRUE,
FALSE);
// Insert row data array into your database of choice here
}
Anything more becomes very dependent on your database, and how you want the data structured in it
if($query)
{
// try to export to excel the whole data ---
//initialize php excel first
ob_end_clean();
//--- create php excel object ---
$objPHPExcel = new PHPExcel();
//define cachemethod
ini_set('memory_limit', '3500M');
$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;
$cacheSettings = array('memoryCacheSize' => '800MB');
//set php excel settings
PHPExcel_Settings::setCacheStorageMethod(
$cacheMethod,$cacheSettings
);
$objPHPExcel->getProperties()->setTitle("export")->setDescription("none");
$objPHPExcel->setActiveSheetIndex(0);
// Field names in the first row
$fields = $query->list_fields();
$col = 0;
foreach ($fields as $field)
{
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field);
$col++;
}
// Fetching the table data
$row = 2;
foreach($query->result() as $data)
{
$col = 0;
foreach ($fields as $field)
{
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $data->$field);
$col++;
}
$row++;
}
$objPHPExcel->setActiveSheetIndex(0);
