Excel
笔者由于工作需要,在OA系统中,需要将EXCEL文件的内容导入到数据库中,同时还需要将数据库中的内容导出到EXCEL文件中。笔者的OA是用PHP开发的,并且应用在WEB页面上,所以直接用PHP处理难度比较大。经过研究,笔者用DELPHI开发了一个ACTIVEX控件,来处理EXCEL文件的数据,然后将数据提交到服务器上,再保存到数据库中,轻松的实现了EXCEL文件数据的导入。导出没有用ACTIVEX控件,直接用PHP处理。方法是将数据直接生成CSV文件,因为CSV是逗号分隔的文本文件,并且可以直接用EXCEL打开处理,所以可以满足要求。 下面将实现的方法介绍一下。导入的页面代码: "人员编号", "FIELDNAME"=>"STUFFID", "FIELDTYPE"=>"A"), array ("CAPTION"=>"开始日期", "FIELDNAME"=>"BEGINDATE", "FIELDTYPE"=>"A"), array ("CAPTION"=>"结束日期", "FIELDNAME"=>"ENDDATE", "FIELDTYPE"=>"A"), array ("CAPTION"=>"合同内容", "FIELDNAME"=>"CONTRACTTEXT", "FIELDTYPE"=>"A"), array ("CAPTION"=>"备注", "FIELDNAME"=>"THISMEMO", "FIELDTYPE"=>"A"), array ("CAPTION"=>"服务器文件名", "FIELDNAME"=>"DOCFILE", "FIELDTYPE"=>"A"), array ("CAPTION"=>"文件类型", "FIELDNAME"=>"FILETYPE", "FIELDTYPE"=>"A"), array ("CAPTION"=>"本地文件名", "FIELDNAME"=>"FILENAME", "FIELDTYPE"=>"A"), array ("CAPTION"=>"文件扩展名", "FIELDNAME"=>"EXTNAME", "FIELDTYPE"=>"A")); //构造SQL语句,字段名部分 $strSQL = "INSERT INTO HR_WORKCONTRACT ("; $strTemp = ""; for ($i = 0; $i ExecSQL ($strSQL.$strTmp)) $do->SetObject ("ERR", "数据导入失败!"); else $do->SetObject ("ERR", "数据导入成功!"); //echo $strSQL.$strTmp; $strTmp = ""; } } } if (trim ($strTmp) != "") { $strTmp = substr ($strTmp, 0, strlen ($strTmp) - 2).";"; if (!$do->ExecSQL ($strSQL.$strTmp)) $do->SetObject ("ERR", "数据导入失败!"); else $do->SetObject ("ERR", "数据导入成功!");//echo $strSQL.$strTmp; } }?>劳动合同信息导入 导入数据的页面如下: 可以显示导入EXCEL文件的所有内容,并且可以手工选择要导入的数据,可以对数据进行临时的修改处理(修改过后数据以红颜色显示,以示区别)。 选择文件界面。可以选择本地硬盘上的EXCEL文件,包括XLS文件和CSV两种格式。
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.
