1. PHPExcel implementation steps for writing to excel

First, you need to introduce the class file and the PHPExcel.php file .

1. Create a new Excel table (instantiate the PHPExcel class)

2. Create a sheet (built-in table) (createSheet() method, setActiveSheet() method, getActiveSheet() method)

3. Fill in data (setCellValue() method)

4. Save the file (PHPExcel_IOFactory::createWriter() method, save method)

2. PHPExcel implements reading Take the Excel operation steps

First you need to introduce the class file and the IOFactory.php file.

1. Instantiate the Excel reading object

2. Load the Excel file (load all, select load)

3. Read the Excel file (read all, load one by one) Row reading)

Use PHPExcel to write and read Excel files code:

<?php
 $dir = dirname(__FILE__); //找出当前脚本所在路径
 /*require $dir.&#39;\lib\PHPExcel_1.8.0_doc\Classes\PHPExcel.php&#39;; //添加读取excel所需的类文件
 $objPHPExcel = new PHPExcel();   //实例化一个PHPExcel()对象
 $objSheet = $objPHPExcel->getActiveSheet(); //选取当前的sheet对象
 $objSheet->setTitle(&#39;helen&#39;);   //对当前sheet对象命名
 //常规方式:利用setCellValue()填充数据
 $objSheet->setCellValue("A1","张三")->setCellValue("B1","李四"); //利用setCellValues()填充数据
 //取巧模式:利用fromArray()填充数据
 $array = array(
 array("","B1","张三"),
 array("","B2","李四")
 );
 $objSheet->fromArray($array); //利用fromArray()直接一次性填充数据
 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel,&#39;Excel2007&#39;); //设定写入excel的类型
 $objWriter->save($dir.&#39;/test.xlsx&#39;);*/ //保存文件
 //利用php读取excel数据
 require $dir.&#39;\lib\PHPExcel_1.8.0_doc\Classes\PHPExcel\IOFactory.php&#39;;
 $filename = $dir.&#39;\test.xlsx&#39;;
 $objPHPExcelReader = PHPExcel_IOFactory::load($filename); //加载excel文件
 foreach($objPHPExcelReader->getWorksheetIterator() as $sheet) //循环读取sheet
 {
 foreach($sheet->getRowIterator() as $row) //逐行处理
 {
  if($row->getRowIndex()<2) //确定从哪一行开始读取
  {
  continue;
  }
  foreach($row->getCellIterator() as $cell) //逐列读取
  {
  $data = $cell->getValue(); //获取cell中数据
  echo $data;
  }
  echo &#39;<br/>&#39;;
 }
 }
?>

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
