PHP class library usage example for exporting excel data

本文实例讲述了PHP实现导出excel数据的类库用法。分享给大家供大家参考，具体如下：

今天一个项目要做一个PHP导出数据用excel保存，在网上找到一个本来是想用phpexcel的，后来发现太难了，就换了一个但导出的歌声是XML

类写的很简单，但很实用。只能简单的导出字符串和数字二种格式。

如果你有兴趣，你可以拿去扩充了，基本够用。

class Excel_XML
{
//定于私有变量，顶部标签
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\">";
//底部标签
private $footer = "</Workbook>";
//定于行数组
private $lines = array();
//设置编码
private $sEncoding;
//设置类型
private $bConvertTypes;
//设置sheet名称
private $sWorksheetTitle;
//构造函数
public function __construct(
 $sEncoding = &#39;UTF-8&#39;,$bConvertTypes = false,$sWorksheetTitle = &#39;Table1&#39;)
{
$this->bConvertTypes = $bConvertTypes;
$this->setEncoding($sEncoding);
$this->setWorksheetTitle($sWorksheetTitle);
}
//设置编码，在构造函数里面默认的事UTF-8格式
public function setEncoding($sEncoding)
{
$this->sEncoding = $sEncoding;
}
//设置excel的头
public function setWorksheetTitle ($title)
{
$title = preg_replace ("/[\\\|:|\/|\?|\*|\[|\]]/", "", $title);
$title = substr ($title, 0, 31);
$this->sWorksheetTitle = $title;
}
//增加行函数（关键函数）
private function addRow ($array)
{
$cells = ""; //设置每个单元为空
foreach ($array as $k => $v)
{
 $type = &#39;String&#39;; //默认类型是字符串
 if ($this->bConvertTypes === true && is_numeric($v)): //判断类型
 { $type = &#39;Number&#39;; }
 $v = htmlentities($v, ENT_COMPAT, $this->sEncoding);
 $cells .= "<Cell><Data ss:Type=\"$type\">" . $v . "</Data></Cell>\n";
}
 $this->lines[] = "<Row>\n" . $cells . "</Row>\n"; //写入数组
}
//增加数组
public function addArray ($array)
{
foreach ($array as $k => $v)
 {$this->addRow ($v);}
}
//导出xml
public function generateXML ($filename = &#39;excel-export&#39;)
{
$filename = preg_replace(&#39;/[^aA-zZ0-9\_\-]/&#39;, &#39;&#39;, $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;
}
}

原理很简单，就是把数据数组，读出来，再用XML的标签封上，在用php自带的header()函数告诉游览器，就可以了。

调用：

public function import()
{
 $data = array(
 1 => array ('学校名称',"队伍名称")
 );
 foreach($this->team as $key=>$value)
 {
  array_push($data,array($key, $value));
 }
 $xls = new Excel_XML('UTF-8', false, 'My Test Sheet'); //实例化函数
 $xls->addArray($data);
 $xls->generateXML('school'); //导出并设置名称
}

上面是的写一个导出方式。在游览器运行就已经导出数组$this->team 里面的键和值了。

希望本文所述对大家PHP程序设计有所帮助。
