本文实例讲述了php实现的操作excel类。分享给大家供大家参考，具体如下：

class Excel

{

static $instance=null;

private $excel=null;

private $workbook=null;

private $workbookadd=null;

private $worksheet=null;

private $worksheetadd=null;

private $sheetnum=1;

private $cells=array();

private $fields=array();

private $maxrows;

private $maxcols;

private $filename;

//构造函数

private function Excel()

{

$this->excel = new COM("Excel.Application") or die("Did Not Connect");

}

//类入口

public static function getInstance()

{

if(null == self::$instance)

{

self::$instance = new Excel();

}

return self::$instance;

}

//设置文件地址

public function setFile($filename)

{

return $this->filename=$filename;

}

//打开文件

public function Open()

{

$this->workbook=$this->excel->WorkBooks->Open($this->filename);

}

//设置Sheet

public function setSheet($num=1)

{

if($num>0)

{

$this->sheetnum=$num;

$this->worksheet=$this->excel->WorkSheets[$this->sheetnum];

$this->maxcols=$this->maxCols();

$this->maxrows=$this->maxRows();

$this->getCells();

}

}

//取得表所有值并写进数组

private function getCells()

{

for($i=1;$imaxcols;$i++)

{

for($j=2;$jmaxrows;$j++)

{

$this->cells[$this->worksheet->Cells(1,$i)->value][]=(string)$this->worksheet->Cells($j,$i)->value;

}

}

return $this->cells;

}

//返回表格内容数组

public function getAllData()

{

return $this->cells;

}

//返回制定单元格内容

public function Cell($row,$col)

{

return $this->worksheet->Cells($row,$col)->Value;

}

//取得表格字段名数组

public function getFields()

{

for($i=1;$imaxcols;$i++)

{

$this->fields[]=$this->worksheet->Cells(1,$i)->value;

}

return $this->fields;

}

//修改制定单元格内容

public function editCell($row,$col,$value)

{

if($this->workbook==null || $this->worksheet==null)

{

echo "Error:Did Not Connect!";

}else{

$this->worksheet->Cells($row,$col)->Value=$value;

$this->workbook->Save();

}

}

//修改一行数据

public function editOneRow($row,$arr)

{

if($this->workbook==null || $this->worksheet==null || $row>=2)

{

}else{

if(count($arr)==$this->maxcols-1)

{

$i=1;

foreach($arr as $val)

{

$this->worksheet->Cells($row,$i)->Value=$val;

$i++;

}

$this->workbook->Save();

}

}

}

//取得总列数

private function maxCols()

{

$i=1;

while(true)

{

if(0==$this->worksheet->Cells(1,$i))

{

return $i;

break;

}

$i++;

}

}

//取得总行数

private function maxRows()

{

while(true)

{

{

return $i;

break;

}

$i++;

}

}

//读取制定行数据

public function getOneRow($row=2)

{

if($row>=2)

{

for($i=1;$imaxcols;$i++)

{

$arr[]=$this->worksheet->Cells($row,$i)->Value;

}

return $arr;

}

}

//关闭对象

public function Close()

{

$this->excel->WorkBooks->Close();

$this->excel=null;

$this->workbook=null;

$this->worksheet=null;

self::$instance=null;

}

};

/*

$excel->WorkBooks->Close();

*/

$excel=Excel::getInstance();

$excel->setFile("D://kaka.xls");

$excel->Open();

$excel->setSheet();

for($i=1;$i<16;$i++ )

{

}

//$excel->editOneRow(2,$arr);

//print_r($excel->getAllData());

include_once('mail.class.php');

$smtpserver="smtp.yeah.net";

$message="你好";

//$message.="首页连接地址为：".$this->link_url."
