EXCEL文件导入MYSQL出错
在的表格很简单,就12列数据,要导入MYSQL
在网上找的代码,自己测试的文件和下载的文件都在一个文件夹里,
有四个文件1,data.xls 2.index.php 3,reader.php(下载的) 4,oleread.inc(下载的)
data.xls表格里数据
num,names,years,season,groups,colornote,colornum,price,types,sizes,materials,note
有两行记录
index代码如下
<?<br />require_once 'reader.php'; // ExcelFile($filename, $encoding); $data = new Spreadsheet_Excel_Reader(); // Set output Encoding. $data->setOutputEncoding('gbk'); <br />//”data.xls”是指要导入到mysql中的excel文件 <br />$data->read('data.xls'); <br />@ $db = mysql_connect('localhost', 'root', '123123') or <br />die("Could not connect to database.");//连接数据库 <br />mysql_query("set names 'gbk'");//输出中文 <br />mysql_select_db('test'); //选择数据库 <br />error_reporting(E_ALL ^ E_NOTICE); <br />for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {<br />//以下注释的for循环打印excel表数据 <br />/* <br />for ($j = 1; $j < = $data->sheets[0]['numCols']; $j++) { <br />echo "\"".$data->sheets[0]['cells'][$i][$j]."\","; <br />} <br />echo "\n"; <br />*/ <br />//以下代码是将excel表数据【3个字段】插入到mysql中, <br />//根据你的excel表字段的多少,改写以下代码吧! <br />$sql = "INSERT INTO test <br />(<br /> num,names,years,season,groups,colornote,colornum,price,types,sizes,materials,note<br />)<br />VALUES('". <br />$data->sheets[0]['cells'][$i][1]."','". <br />$data->sheets[0]['cells'][$i][2]."','". <br />$data->sheets[0]['cells'][$i][4]."','". <br />$data->sheets[0]['cells'][$i][5]."','". <br />$data->sheets[0]['cells'][$i][6]."','". <br />$data->sheets[0]['cells'][$i][7]."','". <br />$data->sheets[0]['cells'][$i][8]."','". <br />$data->sheets[0]['cells'][$i][9]."','". <br />$data->sheets[0]['cells'][$i][10]."','". <br />$data->sheets[0]['cells'][$i][11]."','". <br />$data->sheets[0]['cells'][$i][12]."')"; <br />echo $sql.'< br />'; <br />$res = mysql_query($sql); <br />} <br />?>
运行index.php报以下错误
Fatal error: Call to a member function read() on a non-object in D:\AppServ\www\aaee\index.php on line 4
------解决方案--------------------
第 4 行 $data->read('data.xls');
这和 $data 是在哪里实例化的?
显然你也太粗心了,从网上复制的代码也不认真整理一下
那句 $data = new Spreadsheet_Excel_Reader(); 不还在第二行的注释中吗?

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.
