thinkphp3.2结合PHPExcel导出数据库里所有表的结构

thinkphp3.2结合PHPExcel导出数据库里所有表的结构,含注释
先看图


一、控制器代码如下：    public function out(){<br>         $sql="show tables";//读取库里所有的表<br> <br>         $result=M()->query($sql);<br> <br>         foreach ($result as $k => $v) {<br>             $k++;<br>             $_sql="SHOW FULL COLUMNS FROM ".$v['Tables_in_'.C('DB_NAME')];<br>             $data[][0]=array("表 {$k}.{$v['Tables_in_test']} 表",'','','','','','');<br>             $data[][1]=array("字段","类型","校对","NULL","键","默认","额外","权限","注释");<br>             $data[]=M()->query($_sql);<br>             $data[][]=array();<br>             <br>         }<br> <br>         //导入PHPExcel类库<br>         import("Org.Util.PHPExcel");<br>         import("Org.Util.PHPExcel.Writer.Excel5");<br>         import("Org.Util.PHPExcel.IOFactory.php");<br> <br>         $filename="test_excel";<br>         $headArr=array("ID","字段","类型","NULL","键","默认","额外","注释");<br>         $this->getExcel($filename,$headArr,$data);<br>     }<br> <br> <br>     private    function getExcel($fileName,$headArr,$data){<br>             //对数据进行检验<br>             if(empty($data) || !is_array($data)){<br>                 die("data must be a array");<br>             }<br>             $date = date("Y_m_d",time());<br>             $fileName .= "_{$date}.xls";<br> <br>             //创建PHPExcel对象，注意，不能少了\<br>             $objPHPExcel = new \PHPExcel();<br>             $objProps = $objPHPExcel->getProperties();<br>             <br>             //设置表头<br>             $key = ord("A");<br>             $column = 2;<br>             $objActSheet = $objPHPExcel->getActiveSheet();<br> <br>             foreach ($data as $ke => $row) {                <br>                 foreach($row as $key => $rows){ //行写入<br>                     $span = ord("B");<br>                     foreach($rows as $keyName=>$value){// 列写入<br>                         $j = chr($span);<br>                         $objActSheet->setCellValue($j.$column, $value);<br>                         $span++;<br>                     }<br>                     $column++;<br>                 }<br>             }<br>             <br>             $fileName = iconv("utf-8", "gb2312", $fileName);<br>             //设置活动单指数到第一个表,所以Excel打开这是第一个表<br>             $objPHPExcel->setActiveSheetIndex(0);<br>             header('Content-Type: application/vnd.ms-excel');<br>             header("Content-Disposition: attachment;filename=\"$fileName\"");<br>             header('Cache-Control: max-age=0');<br> <br>               $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');<br>             $objWriter->save('php://output'); //文件通过浏览器下载<br>             exit;<br>     }二、下载附件,把里面的文件及文件夹放到tp的核心目录 ThinkPHP\Library\Org\Util 下

三、数据库的配置项自行配置

四、访问out方法,就可以导出excel表了

五、想要更多的功能自行修改. OVER
