本文实例讲述了PHP将Excel导入数据库及数据库数据导出至Excel的方法。分享给大家供大家参考。具体实现方法如下:
一.导入
导入需要使用能读取Excel的组件,网上也有比较好的组件,这里分享我使用的:下载 提取码:vxyn。(注意两个文件有引用关系)
<?php //传入要导入的Excel的文件名 function import_to_DB($filename) { require_once'reader.php'; $data = new Spreadsheet_Excel_Reader(); //创建读取Excel的对象 $data->setOutputEncoding('utf-8'); //设置读取Excel内容后输出的字符编码 $data->read("data/Excel/{$filename}.xls"); $db = mysql_connect('localhost', '用户名', '密码') or die("Could not connect to database."); //连接数据库 mysql_query("set names 'uft8'"); //输出中文 mysql_select_db('数据库名'); //选择数据库 error_reporting(E_ALL ^ E_NOTICE); for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) { echo $data->sheets[0]['cells'][$i][列数]; //这里可以把每一行相应列的值插到数据库中,如: /* $sql="insert "表名" values(对应项...)"; mysql_query($sql); 可加上错误判断 */ } ?>
总之,能够读出表格中每一行中的相应列$data->sheets[0][行][列]的值,插入操作就好办了。
二.导出
导出可以利用MIME协议轻松导出表格文件,不用依赖任何组件。按如下格式设置header即可导出Excel,同时浏览器进行下载
header('Content-type: text/html; charset=utf-8'); header("Content-type:application/vnd.ms-excel;charset=UTF-8"); //application/vnd.ms-excel指定输出Excel格式 header("Content-Disposition:filename=表格文件名.xls"); //输出的表格名称
完整代码如下:
<?php header('Content-type: text/html; charset=utf-8'); header("Content-type:application/vnd.ms-excel;charset=UTF-8"); header("Content-Disposition:filename=表格文件名.xls"); $conn = mysql_connect("localhost","root","数据库密码") or die("不能连接数据库"); mysql_select_db("数据库名", $conn); mysql_query("set names 'UTF-8'"); $sql="select * from 表名 where 条件"; $result=mysql_query($sql); echo "表头1\t表头2\t表头3\n"; while($row=mysql_fetch_array($result)){ echo $row[0]."\t".$row[1]."\t".$row[2]."\n"; } ?>
这里其实\t就是换格,\n就是换行。在一个网页中设置这个php文件的链接,当点击时浏览器会自动把传过来的流保存为Excel文件。
希望本文所述对大家的php程序设计有所帮助。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
