Jun 23, 2016 pm 02:04 PM

xx.php?id=123 

这里打开SQL里相关值,把里面原来的值显示出来 然后可以编辑 再保存到原来的ID下,这样的PHP页面要怎么写呢。想了半天不明白

SQL表

链接SQL文件如下

<?php$conn = @mysql_connect("localhost","用户","密码");if (!$conn){    die("连接数据库失败:" . mysql_error());}mysql_select_db("数据库名称", $conn);mysql_query("set names 'gb2312'");?>
Copy after login

链接SQL的PHP为 inc.php

查询显示和修改需要单独完成
查询

$link=@mysql_connect(LOCALLHOST,USER,PASS) or die('数据库连接失败!');mysql_select_db(DBNAME,$link);mysql_query('set name gb2312');$sql="select * from 表名";$result=mysql_query($sql,$link);echo '<table width="500">';while($row=mysql_fetch_assoc($result)){   echo '<tr>';   echo '<td>'.$row['id'].'</td>';         ......   echo '</tr>';}echo '</table>';mysql_free_result($result);mysql_close($link);
Copy after login

修改
在表单页面中,把想要修改的数据的ID传到编辑页面,在编辑页面点"修改"按钮后传到动做页面(执行上述连接数据库的操作,执行修改)

查询显示和修改需要单独完成
查询

$link=@mysql_connect(LOCALLHOST,USER,PASS) or die('数据库连接失败!'); mysql_select_db(DBNAME,$link); mysql_query('set name gb2312'); $sql=……
还是不怎么明白,来个类子吧,大神

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
