php数据转入转出

 

有时写程序时后台要求把大量数据导入数据库中，比如考试成绩、电话簿等一般都是存放在excel中的数据，这时我们可把excel导出成csv文件，然后通过以下程序即可批量导入数据到数据库中 上传cvs并导入到数据库中，测试成功（部分代码不规范，如PHP_SELF那里要改写成

代码:

<!-----=========================---->
$_SERVER["HP_SELF"] ）   PHP代码 <?php $fname = $_FILES['MyFile']['name']; $do = copy($_FILES['MyFile']['tmp_name'],$fname); if ($do) { echo"导入数据成功 "; } else { echo ""; } ?> <form ENCTYPE="multipart/form-data" ACTION="<?php echo"".$PHP_SELF.""; ?>" METHOD="OST">   导入CVS数据 <input NAME="MyFile" TYPE="file"> <input VALUE="提交" TYPE="submit"> </form> <? error_reporting(0); //导入CSV格式的文件 $connect=mysql_connect("localhost","a0530093319","123456") or die("could not connect to database"); mysql_select_db("a0530093319",$connect) or die (mysql_error()); $fname = $_FILES['MyFile']['name']; $handle=fopen("$fname","r"); while($data=fgetcsv($handle,10000,",")) { $q="insert into test (code,name,date) values ('$data[0]','$data[1]','$data[2]')"; mysql_query($q) or die (mysql_error());   } fclose($handle); ?>

用php将数据库导出成excel，测试完全成功 PHP代码

代码:

<!-----=========================---->
<?php $DB_Server = "localhost"; $DB_Username = "a0530093319"; $DB_Password = "123456"; $DB_DBName = "a0530093319"; $DB_TBLName = "member";   $savename = date("YmjHis"); $Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect."); mysql_query("Set Names 'gb2312'");   $file_type = "vnd.ms-excel"; $file_ending = "xls"; header("Content-Type: application/$file_type"); header("Content-Disposition: attachment; filename=".$savename.".$file_ending"); header("ragma: no-cache"); header("Expires: 0");   $now_date = date("Y-m-j H:i:s"); $title = "数据库名DB_DBName,数据表DB_TBLName,备份日期now_date";   $sql = "Select * from $DB_TBLName"; $ALT_Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database"); $result = @mysql_query($sql,$Connect) or die(mysql_error()); echo("$title "); $sep = " "; for ($i = 0; $i < mysql_num_fields($result); $i++) { echo mysql_field_name($result,$i) . " "; } print(" "); $i = 0; while($row = mysql_fetch_row($result)) { $schema_insert = ""; for($j=0; $j<mysql_num_fields($result);$j++) { if(!isset($row[$j])) $schema_insert .= "NULL".$sep; elseif ($row[$j] != "") $schema_insert .= "$row[$j]".$sep; else $schema_insert .= "".$sep; } $schema_insert = str_replace($sep."$", "", $schema_insert); $schema_insert .= " "; print(trim($schema_insert)); print " "; $i++; } return (true); ?>
