本文實例講述了php實現的操作excel類。分享給大家供大家參考，具體如下：

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;

//構造函數

private function Excel()

{

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

}

//類入口

public static function getInstance()

{

if(null == self::$instance)

{

self::$instance = new Excel();

}

return self::$instance;

}

//設置文件地址

public function setFile($filename)

{

return $this->filename=$filename;

}

//打開文件

public function Open()

{

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

}

//設置Sheet

public function setSheet($num=1)

{

if($num>0)

{

$this->sheetnum=$num;

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

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

$this->getCells();

}

}

//取得表所有值并寫進數組

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;

}

//返回表格內容數組

public function getAllData()

{

}

//返回制定單元格內容

public function Cell($row,$col)

{

}

//取得表格字段名數組

public function getFields()

{

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

}

//修改制定單元格內容

}else{

}

}

//修改一行數據

}else{

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

{

$i=1;

foreach($arr as $val)

{

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

$i++;

}

$this->workbook->Save();

}

}

}

//取得總列數

private function maxCols()

{

while(true)

{

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

{

return $i;

break;

}

$i++;

}

//取得總行數

private function maxRows()

{

while(true)

{

{

return $i;

break;

}

$i++;

}

}

//讀取制定行數據

public function getOneRow($row=2)

{

if($row>=2)

{

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

{

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

}

return $arr;

}

}

//關閉對象

public function Close()

{

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

$this->excel=null;

$this->workbook=null;

$this->worksheet=null;

self::$instance=null;

}

};

/*

*/

$excel=Excel::getInstance();

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