PHPExcel使用的常用说明以及把PHPExcel整合进CI框架

excel的写入与生成操作：

读取excel

1. 导入一个Excel最简单的方法是使用PHPExel的IO Factory，调用PHPExcel_IOFactory类的静态法load，它可以自动识别文档格式，包括Excel2007、Excel2003XML、OOCalcSYLK、Gnumeric、CSV。返回一个PHPExcel的实例。

//加载工厂类include'PHPExcel/IOFactory.php';//要读取的xls文件路径$inputFileName = './sampleData/example1.xls';/** 用PHPExcel_IOFactory的load方法得到excel操作对象  **/$objPHPExcel = PHPExcel_IOFactory::load($inputFileName);//得到当前活动表格，调用toArray方法，得到表格的二维数组$sheetData =$objPHPExcel->getActiveSheet()->toArray(null,true,true,true);var_dump($sheetData);

1. 创建一个ExcelReader去加载一个Excel文档
如果你知道这个Excel文档的格式，可以建立一个相应的Reader去加载要读取的Excel文档。但是如果你加载了错误的文档类型，可会产生不可预知的错误。

$inputFileName = './sampleData/example1.xls';/** Create a new Excel5 Reader  **/$objReader = new PHPExcel_Reader_Excel5();//    $objReader = new PHPExcel_Reader_Excel2007();//    $objReader = new PHPExcel_Reader_Excel2003XML();//    $objReader = new PHPExcel_Reader_OOCalc();//    $objReader = new PHPExcel_Reader_SYLK();//    $objReader = new PHPExcel_Reader_Gnumeric();//    $objReader = new PHPExcel_Reader_CSV();/** Load $inputFileName to a PHPExcel Object  **/$objPHPExcel = $objReader->load($inputFileName);//得到当前活动sheet$curSheet =$objPHPExcel->getActiveSheet();//以二维数组形式返回该表格的数据$sheetData = $curSheet->toArray(null,true,true,true);var_dump($sheetData);

也可以用PHPExcel_IOFactory的createReader方法去得到一个Reader对象，无需知道要读取文件的格式。

$inputFileType = 'Excel5';//    $inputFileType = 'Excel2007';//    $inputFileType = 'Excel2003XML';//    $inputFileType = 'OOCalc';//    $inputFileType = 'SYLK';//    $inputFileType = 'Gnumeric';//    $inputFileType = 'CSV';$inputFileName = './sampleData/example1.xls';/**  Create a new Reader of the type defined in $inputFileType  **/$objReader = PHPExcel_IOFactory::createReader($inputFileType);/**  Load $inputFileName to a PHPExcel Object  **/$objPHPExcel = $objReader->load($inputFileName);//得到当前活动sheet$curSheet = $objPHPExcel->getActiveSheet();//以二维数组形式返回该表格的数据$sheetData = $curSheet->toArray(null,true,true,true);var_dump($sheetData);如果在读取文件之前，文件格式未知，你可以通过IOFactory 的 identify()方法得到文件类型，然后通过createReader()方法去穿件阅读器。$inputFileName = './sampleData/example1.xls';/**  确定输入文件的格式  **/$inputFileType = PHPExcel_IOFactory::identify($inputFileName);/** 穿件相对应的阅读器  **/$objReader = PHPExcel_IOFactory::createReader($inputFileType);/**  加载要读取的文件  **/$objPHPExcel = $objReader->load($inputFileName);

2. 设置Excel的读取选项
在使用load()方法加载文件之前，可以设置读取选项来控制load的行为.

2.1. ReadingOnly Data from a Spreadsheet File
setReadDataOnly()方法，配置阅读器不关注表格数据的数据类型，都以string格式返回

$inputFileType = 'Excel5';$inputFileName = './sampleData/example1.xls';/**  Create a  nwww.it165.netew Reader of the type defined in $inputFileType  **/$objReader = PHPExcel_IOFactory::createReader($inputFileType);/**  配置单元格数据都以字符串返回  **/$objReader->setReadDataOnly(true);/**  Load $inputFileName to a PHPExcel Object  **/$objPHPExcel = $objReader->load($inputFileName);$sheetData =$objPHPExcel->getActiveSheet()->toArray(null,true,true,true);var_dump($sheetData);

Reading Only Data from a SpreadsheetFile applies to Readers:

Excel2007 YES Excel5 YES Excel2003XML YES

OOCalc YES SYLK NO Gnumeric YES

CSV NO

2.2. ReadingOnly Named WorkSheets from a File
setLoadSheetsOnly(),设置要读取的worksheet，接受worksheet的名称作为参数。

/** PHPExcel_IOFactory */include'PHPExcel/IOFactory.php';  $inputFileType = 'Excel5';//  $inputFileType = 'Excel2007';//  $inputFileType = 'Excel2003XML';//  $inputFileType = 'OOCalc';//  $inputFileType = 'Gnumeric';$inputFileName ='./sampleData/example1.xls';$sheetname = 'Data Sheet #2'; echo 'Loading file',pathinfo($inputFileName,PATHINFO_BASENAME),' using IOFactory with a definedreader type of ',$inputFileType,'<br />';$objReader = PHPExcel_IOFactory::createReader($inputFileType);echo 'Loading Sheet"',$sheetname,'" only<br />';$objReader->setLoadSheetsOnly($sheetname);$objPHPExcel =$objReader->load($inputFileName);echo '<hr />';echo$objPHPExcel->getSheetCount(),' worksheet',(($objPHPExcel->getSheetCount()== 1) ? '' : 's'),' loaded<br /><br />';$loadedSheetNames =$objPHPExcel->getSheetNames();foreach($loadedSheetNames as$sheetIndex => $loadedSheetName) {    echo $sheetIndex,' -> ',$loadedSheetName,'<br />';}

如果想读取多个worksheet，可以传递一个数组

$inputFileType = 'Excel5'; $inputFileName = './sampleData/example1.xls'; $sheetnames = array('Data Sheet #1','Data Sheet #3'); /**  Create a new Reader of the type defined in $inputFileType  **/$objReader = PHPExcel_IOFactory::createReader($inputFileType); /**  Advise the Reader of which WorkSheets we want to load  **/$objReader->setLoadSheetsOnly($sheetnames); /**  Load $inputFileName to a PHPExcel Object  **/$objPHPExcel = $objReader->load($inputFileName);

如果想读取所有worksheet，可以调用setLoadAllSheets()。
