PHP提取excel数据 - 导入MYSQL

PHP提取excel数据 - 导入MYSQL
2010年06月29日 星期二 下午 4:14
这里介绍一个直接将excel文件导入mysql的例子。我花了一晚上的时间测试，无论导入简繁体都不会出现乱码，非常好用。
PHP-ExcelReader,下载地址: http://sourceforge.net/projects/phpexcelreader
说明：
测试环境：MYSQL数据库采用utf8编码.导入EXCEL文档是xls格式,经过测试，xlsx 格式[excel 2007]也OK.
文中红色标注为需要注意的地方，请替换成你配置好的数据，如数据库配置等。运行http://localost/test.php实现导入。
以下是我贴出的详细代码，其中test.php为我写的测试文件，reader.php和oleread.inc文件是从上面提供的网址中下载的。
1. test.php

代码如下:

<?php
require_once './includes/reader.php';
// ExcelFile($filename, $encoding);
$data = new Spreadsheet_Excel_Reader();
// Set output Encoding.
$data->setOutputEncoding('gbk');
//”data.xls”是指要导入到mysql中的excel文件
$data->read('date.xls');
@ $db = mysql_connect('localhost', 'root', '1234') or
die("Could not connect to database.");//连接数据库
mysql_query("set names 'gbk'");//输出中文
mysql_select_db('wenhuaedu'); //选择数据库
error_reporting(E_ALL ^ E_NOTICE);
for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {
//以下注释的for循环打印excel表数据
/*
for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {
echo """.$data->sheets[0]['cells'][$i][$j]."",";
}
echo "n";
*/
//以下代码是将excel表数据【3个字段】插入到mysql中，根据你的excel表字段的多少，改写以下代码吧！
$sql = "INSERT INTO test VALUES('".
$data->sheets[0]['cells'][$i][1]."','".
$data->sheets[0]['cells'][$i][2]."','".
$data->sheets[0]['cells'][$i][3]."')";
echo $sql.'<br />';
$res = mysql_query($sql);
?>
