PHP directly modifies table content DataGrid function implementation code_php skills
Since it needs to be connected to Oracle, I personally feel that phpMyDataGrid is relatively easy to get started with in terms of secondary development and page style.
1. Create test database and tables
create database `guru`; USE `guru`; CREATE TABLE `employees` ( `id` int(6) NOT NULL auto_increment, `name` char(20) default NULL, `lastname` char(20) default NULL, `salary` float default NULL, `age` int(2) default NULL, `afiliation` date default NULL, `status` int(1) default NULL, `active` tinyint(1) default NULL, `workeddays` int(2) default NULL, `photo` char(30) default NULL, PRIMARY KEY (`id`) ) insert into `employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`) values (1, 'Ana', 'Trujillo',2000,45, '2005-05-13',1,1,10, '1.jpg'); insert into `employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`) values (2, 'Jennifer', 'Aniston',3500,23, '2004-10-22',1,0,0, '2.jpg'); insert into `employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`) values (3, 'Michael', 'Norman',1200,19, '2007-01-10',1,1,5, '3.jpg'); insert into `employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`) values (4, 'Vanessa', 'Black',6500,31, '2000-11-05',1,1,30, '4.jpg'); insert into `employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`) values (5, 'Michael', 'Strauss',3200,45, '2006-10-21',2,0,22, '5.jpg'); insert into `employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`) values (6, 'William', 'Brown',2300,21, '2001-03-10',3,1,10, '6.jpg'); insert into `employees` (`id`,`name`,`lastname`,`salary`,`age`,`afiliation`,`status`,`active`,`workeddays`,`photo`) values (7, 'Lucca', 'Normany',2800,36, '2006-10-02',3,1,20, '7.jpg');
2. Introduction to PHP program
phpMyDataGrid is mainly implemented through phpmydatagrid.class.php and dgscripts.js. The total size is less than 100kB, and it is a small software. I won’t go into detail about these two documents. Interested students can “pack them away” and go back to read them slowly. It mainly introduces how to use the software, that is, the example datagrid_for_mysql.php. Let’s take a look at the page diagram first:
Procedure explanation:
<?php include ("phpmydatagrid.class.php"); $objGrid = new datagrid; $objGrid->closeTags(true); $objGrid->friendlyHTML(); $objGrid->methodForm("get"); //连接数据库 $objGrid->conectadb("127.0.0.1", "root", "root", "guru");//加密字符串 $objGrid->salt("Myc0defor5tr0ng3r-Pro3EctiOn"); $objGrid->language("en"); //最后一列显示的功能键,从左向右功能为“新增键”、“编辑键”、“删除键”、“浏览键”。 $objGrid->buttons(true,true,true,true); //修改数值时产生的Form名称 $objGrid->form('employee', true); //可检索列名 $objGrid->searchby("name,lastname"); //需要读取的表 $objGrid->tabla("employees"); //索引值用于修改数据 $objGrid->keyfield("id"); //分页显示行数 $objGrid->datarows(20); //默认排序方式 $objGrid->orderby("name", "ASC"); //显示列设置,相关设置可参考phpmydatagrid.class.php $objGrid->FormatColumn("id", "ID Employee", 5, 5, 1, "50", "center", "integer"); $objGrid->FormatColumn("name", "Name", 30, 30, 0, "150", "left"); $objGrid->FormatColumn("lastname", "Last name", 30, 30, 0, "150", "left"); $objGrid->FormatColumn("age", "Age", 5, 5, 0, "50", "right");//自定义日期格式 $objGrid->FormatColumn("afiliation", "Afiliation Date", 10, 10, 0, "100", "center", "date:dmy:/");//编辑时可以自定义为<Select>模式 $objGrid->FormatColumn("status", "Status", 5, 5, 0, "60", "left", "select:1_Single:2_Married:3_Divorced"); //编辑时可以自定义为<CheckBox>模式 $objGrid->FormatColumn("active", "Active", 2, 2, 0,"50", "center", "check:No:Yes");//自定义货币显示形式 $objGrid->FormatColumn("salary", "Salary", 10, 10, 0, "90", "right", "money:€");//将数据以柱状图显示 $objGrid->FormatColumn("workeddays", "Work days", 5, 2, 0, "50", "right", "chart:percent:val:31"); $objGrid->checkable(); $objGrid->setHeader(); $objGrid->ajax('silent'); echo '<html> <head><title>PHPDataGrid</title></head> <body><div align="center"><br />'; //生成DataGrid $objGrid->grid(); echo '</div></body></html>';//关闭数据库连接 $objGrid->desconectar(); ?>
3. Based on Oracle introduction
To read Oracle, you mainly need to modify the function connecting to MySQL in phpmydatagrid.class.php to Oracle. This article is an Oracle connection through sqlrelay. Of course, you can also use the OCI8 module that comes with PHP (the efficiency is somewhat low ), after modification, save it as phporadatagrid.class.php and then call it in other programs (datagrid_for_oracle.php).
The above is the whole process of teaching you how to directly modify the table content of the DataGrid function in PHP, as well as the understanding of the database. I hope this article will be helpful to your study.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
