php数据导入导出之excel(csv文件)

来源：互联网发布：怎么注册淘宝网店编辑：程序博客网时间：2024/04/29 08:40

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

$_SERVER["PHP_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="POST">

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

<?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("Pragma: 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);
