本文实例讲述了thinkphp普通查询与表达式查询。分享给大家供大家参考。具体分析如下:
一、普通查询方式
a、字符串方式:
b、数组方式:
$data['username']='gege';
$arr=$m->where($data)->find();//传上一个数组进行查询,这种方式默认是and(并且)的关系
注意:如果使用or关系,需要添加数组值
$data['username']='gege';
$data['_logic']='or';//对数组添加_logic赋值为or(或者)关系
二、表达式查询方式
$arr=$m->where($data)->select();
/*
EQ 等于 //大小写没有关系
NEQ不等于
GT 大于
EGT大于等于
LT 小于
ELT小于等于
LIKE 模糊查询*/
$data['username']=array('like','%ge%');//like加通配符查询
$arr=$m->where($data)->select();//所有包含ge的都查询出来
//NOTLIKE不包含
$data['username']=array('notlike','%ge%'); //notlike中间没有空格
$arr=$m->where($data)->select();
//注意:如果一个字段要匹配多个通配符
$data['username']=array('like',array('%ge%','%2%','%五%'),'and');//如果没有第三个值and,默认关系是or关系
$arr=$m->where($data)->select();//或者(or)能查到其中一个值就行
//BETWEEN
$data['id']=array('between',array(5,7));
$arr=$m->where($data)->select();
//SELECT * FROM `tp_user` WHERE ( (`id` BETWEEN 5 AND 7 ) )
$data['id']=array('not between',array(5,7));//注意,not 和 between中间一定要有空格
$arr=$m->where($data)->select();
//IN
$data['id']=array('in',array(4,6,7));
$arr=$m->where($data)->select();
//SELECT * FROM `tp_user` WHERE ( `id` IN (4,6,7) )
$data['id']=array('not in',array(4,6,7));
$arr=$m->where($data)->select();
//SELECT * FROM `tp_user` WHERE ( `id` NOT IN (4,6,7) )
希望本文所述对大家的thinkphp框架程序设计有所帮助。

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.
