用Simple Excel导出xls实现方法

因为前几天写了篇文章，用php-excel-reader类导入excel内容，顺便说些excel导出问题，我用的是simple excel，一个很简单的导出xls类，特好用！
simple excel源码如下：

<?php 
/** 
* Simple excel generating from PHP5 
* 
* @package Utilities 
* @license http://www.opensource.org/licenses/mit-license.php 
* @author Oliver Schwarz <[e-mail]>

*/ 
class Excel_Xml 
{ 
private $header = "<?xml version=\"1.0\" encoding=\"%s\"?\>\n<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns:ss=\"urn:schemas-microsoft-com:office:spreadsheet\" xmlns:html=\"http://www.w3.org/TR/REC-html40\">"; 
private $footer = "</Workbook>"; 
private $lines = array(); 
private $sEncoding; 
private $bConvertTypes; 
private $sWorksheetTitle; 
public function __construct($sEncoding = 'UTF-8', $bConvertTypes = false, $sWorksheetTitle = 'Table1') 
{ 
$this->bConvertTypes = $bConvertTypes; 
$this->setEncoding($sEncoding); 
$this->setWorksheetTitle($sWorksheetTitle); 
} 
public function setEncoding($sEncoding) 
{ 
$this->sEncoding = $sEncoding; 
} 
public function setWorksheetTitle ($title) 
{ 
$title = preg_replace ("/[\\\|:|\/|\?|\*|\[|\]]/", "", $title); 
$title = substr ($title, 0, 31); 
$this->sWorksheetTitle = $title; 
} 
private function addRow ($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" . $cells . "</Row>\n"; 
} 
public function addArray ($array) 
{ 
foreach ($array as $k => $v) 
$this->addRow ($v); 
} 
public function generateXML ($filename = 'excel-export') 
{ 
$filename = preg_replace('/[^aA-zZ0-9\_\-]/', '', $filename); 
header("Content-Type: application/vnd.ms-excel; charset=" . $this->sEncoding); 
header("Content-Disposition: inline; filename=\"" . $filename . ".xls\""); 
echo stripslashes (sprintf($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; 
} 
} 
?>

使用php案例如下:

<?php 
/** 
* @author mckee 
* @blog www.phpddt.com 
*/ 
require_once 'excel.class.php'; 
$xls = new Excel_Xml('UTF-8',false,'测试'); 
$data = array( 
1 => array('名称','地址'), 
2 => array('php点点通','www.phpddt.com'), 
3 => array('百度','www.baidu.com') 
); 
$xls->addArray($data); 
$xls->generateXML('name4test'); ?>

导出结果如下图：
