内含超强通用权限系统 queryphp发布1.0 beta版
目前添加入库验证和修改orm管理方式
ORM Fetch()取得数据后可以提取列
/*
*取得数据结果一列
*$key要取回的字段key
*$p表示 true 为数组形式
* false 为字符组合 $kk为字符间隔
* $kk 表示 取得当前数组里面的值作为字段key 如果$p为false
* 表示是间隔
*$user->getCol('uid',false);array()
*->fetch()->getCol("uid"); "33,22"
*$user->getCol("isMar",true,'uid'); $col[$row['uid']]=$row['isMar'];
*/
比如 我们取得数据如上面所示
$user->getRecord();如是上图数据
$user->getCol("名字");取得名字一列组成数组
array("0"=>"伍德里",
"1"=>"张三风",.......)
这样的数组
如果$user->getCol("序号",false);取得一列为字符串组装,注意第二个参数为false,默认为true,返回数组
$str="59,58,57,56.......";这样子,这样子可以使用->WhereIn("uid",$str)查询
如果这样子:$user->getCol("名字",true,"序号");这样取得数组为序号为键,名字为值
array("59"=>"伍德里",
"58"=>"张三风",
"57"=>"里斯".......);
csdn不给上图了

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.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
