PHP教程：PHP实现导出excel数据的类库用法示例

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(
 $sEncoding = 'UTF-8',$bConvertTypes = false,$sWorksheetTitle = 'Table1')
{
$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)
{
 $type = 'String'; //默认类型是字符串
 if ($this->bConvertTypes === true && is_numeric($v)): //判断类型
 { $type = 'Number'; }
 $v = htmlentities($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 = '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;
}
}

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
}
