phpexcelreader读取excel自动生成表和字段
这个主要是采用phpexcelreader的功能实现,根据excel的文件名和excel第一行生成表名及字段,数据从第二行开始依次导入。



phpexcelreader下载地址 : http://sourceforge.net/projects/phpexcelreader/

下载下来有个 “phpExcelReader.zip”的压缩包。解压,我们需要的只有 Excel 文件夹的内容,首先把 “oleread.inc” 改为 “oleread.inc.php”

修改“reader.php”文件

修改第31行  require_once 'Spreadsheet/Excel/Reader/OLERead.php';
改为 ”   :     require_once 'oleread.inc.php';
                 第 261行 =&  改为 =  号就 OK 了

源码及示例文件,以及流程都在下载文件里!
本人php新手,错误之处还请谅解。

上传文件页面!

上传文件处理

<?phpif (! empty ( $_FILES ['upfile'] ['name'] )) {	if ($_FILES ['upfile'] ['error'] > 0) {		switch ($_FILES ['upfile'] ['error']) {			case 1 :				$errorMsg = "上传文件超过限制!";				break;			case 2 :				$errorMsg = "上传文件超过前台指定大小!";				break;			case 3 :				$errorMsg = "上传文件不完整!";				break;			case 4 :				$errorMsg = "没有上传文件!";				break;		}		echo $errorMsg;	} else {				if (! is_dir ( 'upload' )) {			mkdir ( 'upload' );		}				//判断文件格式是否正确		$imgType = array ('application/octet-stream' ,'application/vnd.ms-excel');		if (! in_array ( $_FILES ['upfile'] ['type'], $imgType )) {			echo $_FILES ['upfile'] ['type'] . "不符合文件类型";			exit ();		}				if (is_uploaded_file ( $_FILES ['upfile'] ['tmp_name'] )) {						$toFileName = 'upload/' . $_FILES ['upfile'] ['name'];			//移动临时文件到指定文件夹			if (move_uploaded_file ( $_FILES ['upfile'] ['tmp_name'], $toFileName )) {				$excelFileName = $toFileName;			} else {				echo "文件上传失败!";			}		} else {			echo "不是上传文件!";		}		}} else {	echo "请选择上传文件!";} ?>
