cách sử dụng phpexcel để đọc dữ liệu và chèn vào cơ sở dữ liệu?

Question

Tôi có ứng dụng php nơi tôi muốn đọc dữ liệu từ excel, Chèn vào cơ sở dữ liệu và sau đó tạo báo cáo pdf cho người dùng cụ thể. Tôi đã tìm kiếm trên internet rất nhiều nhưng không có gì cụ thể về cả hai thứ. nếu ai đó có thể cung cấp một hướng dẫn hoặc một cái gì đó, đó sẽ là một trợ giúp thực sự.

Answer 1

Sử dụng thư viện PHPExcel để đọc một tập tin Excel và chuyển dữ liệu vào một cơ sở dữ liệu

// 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 
} 

Bất cứ điều gì hơn trở nên rất phụ thuộc vào cơ sở dữ liệu của bạn, và làm thế nào bạn muốn dữ liệu có cấu trúc trong đó

Trong để đọc dữ liệu từ microsoft excel 2007 bởi codeigniter, chỉ cần tạo một hàm trợ giúp excel_helper.php và thêm vào sau trong:

 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;

Đây là một câu trả lời rất gần đây cho câu hỏi này từ file: 07reader.php

<?php 


error_reporting(E_ALL); 
ini_set('display_errors', TRUE); 
ini_set('display_startup_errors', TRUE); 

define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />'); 

date_default_timezone_set('Europe/London'); 

/** Include PHPExcel_IOFactory */ 
require_once '../Classes/PHPExcel/IOFactory.php'; 


if (!file_exists("05featuredemo.xlsx")) {

Answer 6

Sử dụng thư viện PHPExcel, đoạn code sau sẽ làm.

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++; 
}
