PHP 解析PHPExcel使用的常用说明以及把PHPExcel整合进CI框架的介绍
excel的写入与生成操作：
复制代码代码如下:
include 'PHPExcel.php';
include 'PHPExcel/Writer/Excel2007.php';
//或者include 'PHPExcel/Writer/Excel5.php'; 用于输出.xls的
include 'PHPExcel/IOFactory.php';//phpexcel工厂类
//创建一个excel
$objPHPExcel = new PHPExcel();
//保存excel—2007格式
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
//也可以使用
//$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, "Excel2007");
//或者$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel); 非2007格式
$objWriter- save("xxx.xlsx");
//直接输出到浏览器
$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
header("Pragma: html' target='_blank'>public");
header("Expires: 0″);
header("Cache-Control:must-revalidate, post-check=0, pre-check=0″);
header("Content-Type:application/force-download");
header("Content-Type:application/vnd.ms-execl");
header("Content-Type:application/octet-stream");
header("Content-Type:application/download");;
header('Content-Disposition:attachment;filename="resume.xls"');
header("Content-Transfer-Encoding:binary");
$objWriter- save('php://output');
//直接生成文件

//垂直居中
$objPHPExcel- getActiveSheet()- getStyle('A18')- getAlignment()- setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
设置column的border
$objPHPExcel- getActiveSheet()- getStyle('A4')- getBorders()- getTop()- setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

$objPHPExcel- getActiveSheet()- getStyle('E4')- getBorders()- getTop()- setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
设置border的color
$objPHPExcel- getActiveSheet()- getStyle('D13')- getBorders()- getLeft()- getColor()- setARGB('FF993300');
$objPHPExcel- getActiveSheet()- getStyle('D13')- getBorders()- getTop()- getColor()- setARGB('FF993300');
$objPHPExcel- getActiveSheet()- getStyle('D13')- getBorders()- getBottom()- getColor()- setARGB('FF993300');
$objPHPExcel- getActiveSheet()- getStyle('E13')- getBorders()- getTop()- getColor()- setARGB('FF993300');
$objPHPExcel- getActiveSheet()- getStyle('E13')- getBorders()- getBottom()- getColor()- setARGB('FF993300');
$objPHPExcel- getActiveSheet()- getStyle('E13')- getBorders()- getRight()- getColor()- setARGB('FF993300');
设置填充颜色
$objPHPExcel- getActiveSheet()- getStyle('A1')- getFill()- setFillType(PHPExcel_Style_Fill::FILL_SOLID);

$objPHPExcel- getActiveSheet()- getStyle('B1')- getFill()- setFillType(PHPExcel_Style_Fill::FILL_SOLID);
$objPHPExcel- getActiveSheet()- getStyle('B1')- getFill()- getStartColor()- setARGB('FF808080');
//加图片
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing- setName('Logo');
$objDrawing- setDescription('Logo');
$objDrawing- setPath('./images/officelogo.jpg');
$objDrawing- setHeight(36);
$objDrawing- setWorksheet($objPHPExcel- getActiveSheet());
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing- setName('Paid');
$objDrawing- setDescription('Paid');
$objDrawing- setPath('./images/paid.png');
$objDrawing- setCoordinates('B15');
$objDrawing- setOffsetX(110);
$objDrawing- setRotation(25);
$objDrawing- getShadow()- setVisible(true);
$objDrawing- getShadow()- setDirection(45);
$objDrawing- setWorksheet($objPHPExcel- getActiveSheet());
//处理中文输出问题
//需要将字符串转化为UTF-8编码，才能正常输出，否则中文字符将输出为空白，如下处理：
$str = iconv('gb2312', 'utf-8', $str);
或者你可以写一个函数专门处理中文字符串：
function convertUTF8($str)
{
if(empty($str)) return '';
return iconv('gb2312', 'utf-8', $str);
}

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。
复制代码代码如下:
//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。
复制代码代码如下:
$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。
复制代码代码如下:
$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。
复制代码代码如下:
$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
复制代码代码如下:
$inputFileType = 'Excel5';
$inputFileName = './sampleData/example1.xls';
/** Create a new 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);

返回数据：
复制代码代码如下:
array(8) {
[1]=
array(6) {
["A"]=
string(15) "Integer Numbers"
["B"]=
string(3)"123"
["C"]=
string(3)"234"
["D"]=
string(4)"-345"
["E"]=
string(3)"456"
["F"]=
NULL
}
[2]=
array(6) {
["A"]=
string(22) "Floating PointNumbers"

["B"]=
string(4) "#N/A"
["C"]=
string(7) "#DIV/0!"
["D"]=

}
}

["E"]=
float(-45.678)
["F"]=
float(56.78)
}
[3]=
array(6) {
["A"]=
string(7) "Strings"
["B"]=
string(5) "Hello"

}
}

Reading Only Data from a SpreadsheetFile applies to Readers:
Excel2007 YES Excel5 YES Excel2003XML YES
OOCalc YES SYLK NO Gnumeric YES
CSV NO2.2.ReadingOnly Named WorkSheets from a File
setLoadSheetsOnly(),设置要读取的worksheet，接受worksheet的名称作为参数。
复制代码代码如下:
/** 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
复制代码代码如下:
$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()。
