php如何导出excel文件

最近想用php把自己的数据保存起来，并且是excel格式。

可以按一下方法：

第一步：写一个类文件（php-excel.class.php）

        public function __construct($sEncoding = 'UTF-8', $bConvertTypes = false, $sWorksheetTitle = 'Table1')

        {

        private function addRow ($array)

        {

            $cells = "";

                foreach ($array as $k => $v):

                        $type = 'String';

                        if ($this->bConvertTypes === true && is_numeric($v)):

                                $type = 'Number';

                        endif;

                        $v = htmlentities($v, ENT_COMPAT, $this->sEncoding);

                        $cells .= "<Cell><Data ss:Type=\"$type\">" . $v . "</Data></Cell>\n"; 

                endforeach;

                $this->lines[] = "<Row>\n" . $cells . "</Row>\n";

        }



        /**

         * Add an array to the document

         * @param array 2-dimensional array

         */

        public function addArray ($array)

        {

                foreach ($array as $k => $v)

                        $this->addRow ($v);

        }

         * @param string $filename Name of excel file to generate (...xls)

         */

        public function generateXML ($filename = 'excel-export')

        {

                // correct/validate filename

                $filename = preg_replace('/[^aA-zZ0-9\_\-]/', '', $filename);

        

                // deliver header (as recommended in php manual)

                header("Content-Type: application/vnd.ms-excel; charset=" . $this->sEncoding);

                header("Content-Disposition: inline; filename=\"" . $filename . ".xls\"");



                // print out document to the browser

                // need to use stripslashes for the damn ">"

                echo stripslashes (sprintf($this->header, $this->sEncoding));

                echo "\n<Worksheet ss:Name=\"" . $this->sWorksheetTitle . "\">\n<Table>\n";

                foreach ($this->lines as $line)

                        echo $line;



                echo "</Table>\n</Worksheet>\n";

                echo $this->footer;

        }



}



?>

第二步：调用实例（test.php）

<?php

// load library

require 'php-excel.class.php';



// create a simple 2-dimensional array

$data = array(

        array ('商户编号', '商户名称'),

        array('0001', '我是商户01'),

        array('0002', '我是商户02'),

        array('0003', '我是商户03'),

        array('0004', '我是商户04'),

        array('0005', '我是商户05'),

        array('0006', '我是商户06'),

        array('0007', '我是商户07'),

        array('0008', '我是商户08'),

        array('0009', '我是商户09'),

        array('0010', '我是商户10')

        );

// generate file (constructor parameters are optional)

$xls = new Excel_XML('UTF-8', false, 'My Test Sheet');

$xls->addArray($data);

$xls->generateXML('my-test');



?>

第三步：运行test.php 文件，就会自动保存。

注意：文件必须是UTF-8格式。

　　　my-test是你要保存的文件名称，这个文件名必须是英文才可以。
