利用PHP-ExcelReader实现PHP导入Excel数据[不通过CSV]
最近因項目需求，要實現將excel文件通過php頁面導入mysql數據庫中。在網上搜了很多這方面的資料，發現都是將excel文件另存為csv文件，然后從csv文件導入。這里介紹一個直接將excel文件導入mysql的例子。我花了一晚上的時間測試，無論導入簡繁體都不會出現亂碼，非常好用。
整理：leo 2007.12.21?凌晨
PHP-ExcelReader,下載地址:?http://sourceforge.net/projects/phpexcelreader
?
說明：
測試環境：MYSQL數據庫采用utf8編碼.導入EXCEL文檔是xls格式,經過測試，xlsx?格式[excel 2007]也OK.
文中紅色標注為需要注意的地方，請替換成你配置好的數據，如數據庫配置等。運行http://localost/test.php實現導入。
以下是我貼出的詳細代碼，其中test.php為我寫的測試文件，read.php和oleread.inc文件是從上面提供的網址中下載的。
?
1.????test.php
?
<?php
require_once 'reader.php';
?
// ExcelFile($filename, $encoding);
$data = new Spreadsheet_Excel_Reader();
?
// Set output Encoding.
$data->setOutputEncoding('gbk');
?
//”data.xls”是指要導入到mysql中的excel文件
$data->read('data.xls');
?
@ $db = mysql_connect('localhost', 'root', '123456') or
???????die("Could not connect to database.");//連接數據庫
mysql_query("set names 'gbk'");//輸出中文
mysql_select_db('mydb');???????//選擇數據庫
error_reporting(E_ALL ^ E_NOTICE);
?
for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {
//以下注釋的for循環打印excel表數據
/*
?for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {
????????????echo "/"".$data->sheets[0]['cells'][$i][$j]."/",";
???????????}
???????????echo "/n";
*/
//以下代碼是將excel表數據【3個字段】插入到mysql中，根據你的excel表字段的多少，改寫以下代碼吧！
????$sql = "INSERT INTO test VALUES('".
???????????????$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);
}
?
?>
?
