    php 将excel导入mysql

    2016-06-13 12:20:35原创280
    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

    复制代码 代码如下:


    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.'
    ';
    $res = mysql_query($sql);


    贴出其中包含的文件
