有時寫程序時後台要求把大量數據導入數據庫中，比如考試成績、電話簿等一般都是存放在excel中的數據，這時我們可把Excel導出成csv文件，然後通過以下程序即可批量導入數據到數據庫中
上傳cvs並導入到數據庫中，測試成功（部分代碼不規范，如PHP_SELF那裡要改寫成$_SERVER["PHP_SELF"] ）
PHP代碼
<?PHP
$fname = $_FILES['MyFile']['name'];
$do = copy($_FILES['MyFile']['tmp_name'],$fname);
if ($do)
{
echo"導入數據成功<br>";
} else {
echo "";
}
?>
<form ENCTYPE="multipart/form-data" ACTION="<?php echo"".$PHP_SELF.""; ?>" METHOD="POST">
<p>導入CVS數據 <input NAME="MyFile" TYPE="file"> <input VALUE="提交" TYPE="submit">
</p>
</form>
<?
error_reporting(0);
//導入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將數據庫導出成Excel，測試完全成功
PHP代碼
<?PHP
$DB_Server = "localhost";
$DB_Username = "root";
$DB_PassWord = "";
$DB_DBName = "ishop";
$DB_TBLName = "oi_mall_payment";
$savename = date("YmjHis");
$Connect = @MySQL_connect($DB_Server, $DB_Username, $DB_PassWord) or dIE("Couldn't connect.");
MySQL_query("Set Names 'gbk'");
$file_type = "vnd.ms-Excel";
$file_ending = "xls";
header("Content-Type: application/$file_type;charset=big5");
header("Content-Disposition: attachment; filename=".$savename.".$file_ending");
//header("Pragma: no-cache");
$now_date = date("Y-m-j H:i:s");
$title = "數據庫名:$DB_DBName,數據表:$DB_TBLName,備份日期:$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\n");
$sep = "\t";
for ($i = 0; $i < MySQL_num_fIElds($result); $i++) {
echo MySQL_fIEld_name($result,$i) . "\t";
}
print("\n");
$i = 0;
while($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);
$schema_insert .= "\t";
print(trim($schema_insert));
print "\n";
$i++;
}
return (true);
?>
