读取中文的xls、csv文件会有问题，网上找了下资料，发现PHPExcel类库好用，官网地址：http://phpexcel.codeplex.com/ 

1、读取xls文件内容

<?php
    //向xls文件写入内容
    error_reporting(E_ALL);
    ini_set('display_errors', TRUE);    
    include 'Classes/PHPExcel.php';            
    include 'Classes/PHPExcel/IOFactory.php';  
    //$data:xls文件内容正文
    //$title:xls文件内容标题
    //$filename:导出的文件名
    //$data和$title必须为utf-8码，否则会写入FALSE值
    function write_xls($data=array(), $title=array(), $filename='report'){
        $objPHPExcel = new PHPExcel();
        //设置文档属性，设置中文会产生乱码，待完善...
        // $objPHPExcel->getProperties()->setCreator("云舒")
                             // ->setLastModifiedBy("云舒")
                             // ->setTitle("产品URL导出")
                             // ->setSubject("产品URL导出")
                             // ->setDescription("产品URL导出")
                             // ->setKeywords("产品URL导出");
        $objPHPExcel->setActiveSheetIndex(0);
        
        $cols = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
        //设置标题
        for($i=0,$length=count($title); $i<$length; $i++) {
            //echo $cols{$i}.'1';
            $objPHPExcel->getActiveSheet()->setCellValue($cols{$i}.'1', $title[$i]);
        }
        //设置标题样式
        $titleCount = count($title);
        $r = $cols{0}.'1';
        $c = $cols{$titleCount}.'1';
        $objPHPExcel->getActiveSheet()->getStyle("$r:$c")->applyFromArray(
            array(
                'font'    => array(

                        'style' => PHPExcel_Style_Border::BORDER_THIN
                    )
                ),
                'fill' => array(

                )
            )
        );
        
        $i = 0;
        foreach($data as $d) {  //这里用foreach,支持关联数组和数字索引数组
            $j = 0;
            foreach($d as $v) {   //这里用foreach,支持关联数组和数字索引数组
                $objPHPExcel->getActiveSheet()->setCellValue($cols{$j}.($i+2), $v);
                $j++;
            }

        }
