This article introduces to students how to use the phpexcel plug-in to quickly implement the operation code for excel tables. Friends who need to know more about it are welcome to refer to it.
The first step is to extract the data from excel. Here I use an open source PHP excel class: phpexcel. Details of the project http://phpexcel.codeplex.com/.
I am currently using version phpexcel1.7.3. After decompression, there are a PHPExcel and PHPExcel.php file inside.
We mainly use that PHP file. See the file directory structure below
This version is said to support excel2007, but the xlsx I edited using 2007 cannot get support from this library. So I converted it to 2003. It feels very supportive.
The specific usage is introduced below:
The code is as follows |
Copy code |
代码如下 |
复制代码 |
require_once('./phpexcel1.7.3/PHPExcel.php');
$php_excel_obj = new PHPExcel();
$php_reader = newPHPExcel_Reader_Excel2007();
if(!$php_reader->canRead($file_name)){
$php_reader= new PHPExcel_Reader_Excel5();
if(!$php_reader->canRead($file_name)){
echo'NO Excel!';
}
}
$php_excel_obj = $php_reader->load($file_name);
$current_sheet =$php_excel_obj->getSheet(0);
|
require_once('./phpexcel1.7.3/PHPExcel.php');
$php_excel_obj = new PHPExcel();
代码如下 |
复制代码 |
$all_column =$current_sheet->getHighestColumn();
$all_row =$current_sheet->getHighestRow();
|
$php_reader = newPHPExcel_Reader_Excel2007();
if(!$php_reader->canRead($file_name)){
$php_reader= new PHPExcel_Reader_Excel5();
If(!$php_reader->canRead($file_name)){
echo'NO Excel!';
代码如下 |
复制代码 |
$all_arr = array();
$c_arr = array();
//字符对照表
for($r_i = 1; $r_i<=$all_row; $r_i++){
$c_arr= array();
for($c_i= 'A'; $c_i<= 'B'; $c_i++){
$adr= $c_i . $r_i;
$value= $current_sheet->getCell($adr)->getValue();
if($c_i== 'A' && empty($value) ) break;
if(is_object($value)) $value= $value->__toString();
$c_arr[$c_i]= $value;
}
$c_arr&& $all_arr[] = $c_arr;
}
|
}
}
$php_excel_obj = $php_reader->load($file_name);
$current_sheet =$php_excel_obj->getSheet(0);
|
The main function above is to initialize the relevant excel class and load the first excel sheet
The code is as follows |
Copy code |
$all_column =$current_sheet->getHighestColumn();
$all_row =$current_sheet->getHighestRow();
|
The above respectively obtains the maximum column value of the table (letter representation such as: 'G'), and the maximum number of rows (numeric representation)
The following will use a loop to read the data in excel into excel:
The code is as follows |
Copy code |
$all_arr = array();
$c_arr = array();
//Character comparison table
for($r_i = 1; $r_i<=$all_row; $r_i++){<🎜>
$c_arr= array();<🎜>
for($c_i= 'A'; $c_i<= 'B'; $c_i++){<🎜>
$adr= $c_i . $r_i;<🎜>
$value= $current_sheet->getCell($adr)->getValue();
If($c_i== 'A' && empty($value) ) break;
If(is_object($value)) $value= $value->__toString();
$c_arr[$c_i]= $value;
}
$c_arr&& $all_arr[] = $c_arr;
}

The following is a brief introduction to the write operation of phpexcel. This operation is often used to import data from the database into excel for easy display and more beautiful effects.
The code is as follows
代码如下 |
复制代码 |
require_once('./phpexcel1.7.3/PHPExcel.php');
$excel_obj = new PHPExcel();
$objWriter = newPHPExcel_Writer_Excel5($excel_obj);
$excel_obj->setActiveSheetIndex(0);
$act_sheet_obj=$excel_obj->getActiveSheet();
$act_sheet_obj->setTitle('sheet');
$act_sheet_obj->setCellValue('A1', '字符串内容');
$act_sheet_obj->setCellValue('A2', 26);
$file_name = "output.xls";
$objWriter->save($file_name);

require_once('./phpexcel1.7.3/PHPExcel.php');
$excel_obj = new PHPExcel();
$objWriter = newPHPExcel_Writer_Excel5($excel_obj);
$excel_obj->setActiveSheetIndex(0);
$act_sheet_obj=$excel_obj->getActiveSheet();
$act_sheet_obj->setTitle('sheet');
$act_sheet_obj->setCellValue('A1', 'String content');
$act_sheet_obj->setCellValue('A2', 26);
$file_name = "output.xls";
$objWriter->save($file_name);
Used to export mysql data to excel files using php, maybe it can be used as quick material:
function to_excel($sql,$excel_name)//The parameters are SQL statements and the exported excel file name
{
include_once('PHPExcel/Classes/PHPExcel.php');//Include class files
include_once('PHPExcel/Classes/PHPExcel/Writer/Excel2007.php');//Include class files
$objPHPExcel=new PHPExcel();//Create a new excel file class
$re=mysql_query($sql);//Execute SQL to get the data set
$i=1;
while($list=mysql_fetch_row($re))//Loop to get data row by row
{
$objPHPExcel->getActiveSheet()->setCellValue('A'.$i,$list[0]);//Write $list[0] in column A and row i of excel
$objPHPExcel->getActiveSheet()->setCellValue('B'.$i,$list[1]);//And so on
$objPHPExcel->getActiveSheet()->setCellValue('C'.$i,$list[2]);
$objPHPExcel->getActiveSheet()->setCellValue('D'.$i,$list[3]);
$objPHPExcel->getActiveSheet()->setCellValue('E'.$i,$list[4]); |
$objPHPExcel->getActiveSheet()->setCellValue('F'.$i,$list[5]);
$objPHPExcel->getActiveSheet()->setCellValue('G'.$i,$list[6]);
$objPHPExcel->getActiveSheet()->setCellValue('H'.$i,$list[7]);
$objPHPExcel->getActiveSheet()->setCellValue('I'.$i,$list[8]);
$i++;
}
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);//Instantiate the excel data object into an excel file object
$objWriter->save($excel_name.".xlsx");//Export and write to the current directory, named according to $excel_name
echo "OK! Exported as ".$excel_name;
}
?>
