PHPExcel是个很强大的类库，以前只使用过它生成Excel文件，非常方便。
今天接到个项目要读取Excel的文件，以前也做过Excel转换写入数据库的工作，
不过相对简单一些，是转换成CSV格式再进行解析的。
首先下载PHPExcel类库。http://phpexcel.codeplex.com/
包含PHPExcel类库文件，如果不能确定文件类型的话可以使用PHPExcel_IOFactory::identify方法返回文件的类型，传递给该函数一个文件名就可以。
然后根据返回的文件类型创建该类型的读取对象，进行文件的load。
之后就可以进行数据的读取了，
具体代码如下所示：
/*
* 将excel转换为数组 by aibhsc
* */
require(ROOT_PATH . 'includes/PHPExcel.php');//引入PHP EXCEL类
function format_excel2array($filePath='',$sheet=0){
if(empty($filePath) or !file_exists($filePath)){die('file not exists');}
$PHPReader = new PHPExcel_Reader_Excel2007(); //建立reader对象
if(!$PHPReader->canRead($filePath)){
$PHPReader = new PHPExcel_Reader_Excel5();
if(!$PHPReader->canRead($filePath)){
echo 'no Excel';
return ;
}
}
$PHPExcel = $PHPReader->load($filePath); //建立excel对象
$currentSheet = $PHPExcel->getSheet($sheet); //**读取excel文件中的指定工作表*/
$allColumn = $currentSheet->getHighestColumn(); //**取得最大的列号*/
$allRow = $currentSheet->getHighestRow(); //**取得一共有多少行*/
$data = array();
for($rowIndex=1;$rowIndex<=$allRow;$rowIndex++){ //循环读取每个单元格的内容。注意行从1开始，列从A开始
for($colIndex='A';$colIndex<=$allColumn;$colIndex++){
$addr = $colIndex.$rowIndex;
$cell = $currentSheet->getCell($addr)->getValue();
if($cell instanceof PHPExcel_RichText){ //富文本转换字符串
$cell = $cell->__toString();
}
$data[$rowIndex][$colIndex] = $cell;
}
}
return $data;
}
使用方法：
$filePath = ROOT_PATH.'data/diamondStock.xlsx'; //钻石库存文件
$data = format_excel2array($filePath);
print_r($data);die;
输出结果示例：
