How to import Excel data with PHPExcel

This article mainly introduces the method of importing Excel data into PHPExcel. It has certain reference value. Now I share it with you. Friends in need can refer to it.

1: Use composer to download phpoffice/phpexcel or Directly download the installation package

composer require phpoffice/phpexcel

二

1: Import data

Principle: Read the file and get the maximum row and column of the file. Then assemble the data and import it into the database.

Note: If your Excel file is encrypted, it cannot be read. I really wasted a lot of time on this. If anyone knows how to do it, Solved, please let me know. Thank you.

Let’s take a look at how to implement it

Implementation method

  public static function importExcel($file = '', $sheet = 0)
    {        
    $file = iconv("utf-8", "gb2312", $file);   //转码
        if (empty($file) OR !file_exists($file)) {            
        die('file not exists!');
        }        
        $objRead = new PHPExcel_Reader_Excel2007();   //建立reader对象
        if (!$objRead->canRead($file)) {            
        $objRead = new PHPExcel_Reader_Excel5();            
        if (!$objRead->canRead($file)) {                
        die('No Excel!');
            }
        }        
        $cellName = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q',
            'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'AA', 'AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'AH', 'AI',
            'AJ', 'AK', 'AL', 'AM', 'AN', 'AO', 'AP', 'AQ', 'AR', 'AS', 'AT', 'AU', 'AV', 'AW', 'AX', 'AY', 'AZ'];        $obj = $objRead->load($file);  //建立excel对象
        $currSheet = $obj->getSheet($sheet);   //获取指定的sheet表
        $columnH = $currSheet->getHighestColumn();   //取得最大的列号
        $columnCnt = array_search($columnH, $cellName);        
        $rowCnt = $currSheet->getHighestRow();   //获取总行数

        $data = [];        
        for ($_row = 1; $_row <= $rowCnt; $_row++) {  //读取内容
            for ($_column = 0; $_column <= $columnCnt; $_column++) {                
            $cellId = $cellName[$_column] . $_row;                
            $cellValue = $currSheet->getCell($cellId)->getValue();                
            $data[$_row][$_column] = $cellValue;
            }
        }        $return_data = [];        
        foreach ($data as $k => $v) {            
        if ($k > 1) {                
        $test = array_combine($data[1], $data[$k]);                
        array_push($return_data, $test);
            }
        }        
        return $return_data;
    }

//Lite version

 public static function importExcel($file = '', $sheet = 0)
    {        $file = iconv("utf-8", "gb2312", $file);   //转码
        if (empty($file) OR !file_exists($file)) {            
        die('file not exists!');
        }        $objRead = new PHPExcel_Reader_Excel2007();   //建立reader对象
        if (!$objRead->canRead($file)) {            
        $objRead = new PHPExcel_Reader_Excel5();            
        if (!$objRead->canRead($file)) {                
        die('No Excel!');
            }
        } 
        $obj = $objRead->load($file);  //建立excel对象
        $data =$obj->getSheet($sheet)->toArray();//获取为数组

        $return_data = [];        
        foreach ($data as $k => $v) {            
        if ($k > 0) {                
        $test = array_combine($data[0], $data[$k]);                
        array_push($return_data, $test);
            }
        } 
        return $return_data;
    }

Note that if the file is too large, PHP will take too long to read, we can set it.

 set_time_limit(0);//0代表永久
