php 连接mysql实例代码_MySQL
bitsCN.com
<?php <br />mysql_connect("localhost", "root","1981427") //连接位于localhost的服务器,用户名为root <br>?>
连接再选择数据库
<?php <br /><br>@mysql_select_db("test") //选择数据库mydb<br><br>?>
这样我们就可以实现连接到数据库了
可能碰到的问题
运行代码出现:Call to undefined function 'mysql_connect()'… 失败
这个提示function undefined是说没有mysql_connect()函数,
解决方法如下
将php_mysql.dll和libmysql.dll文件拷贝至c:winntsystem32中(我漏了libmysql.dll)
找到php.ini中的;extension=php_mysql,去掉前面的";" 重启服务器
好了万事具备了,现在我们就差一个简单的连接实例
例1
conn.php文件代码如下:
<?php <br />$conn = @mysql_connect("localhost", "root", "root") or die("数据库链接错误");<br>mysql_select_db("data", $conn);//data为数据库名称<br>mysql_query("set names 'GBK'"); //使用GBK中文编码;<br>?>
index.php文件代码如下:
<?php <br /> include("conn.php");//引入conn.php文件<br> $SQL="SELECT * FROM `table` order by id desc";<br> $query=mysql_query($SQL);<br> while($row=mysql_fetch_array($query)){<br>?>
显示数据内容:
=$row[user]?><br><br> }<br>?>
这样我们就实现的简单的php mysql连接并查询出我们需要的数据了。

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.

Arrays are linear data structures used to process data in programming. Sometimes when we are processing arrays we need to add new elements to the existing array. In this article, we will discuss several ways to add elements to the end of an array in PHP, with code examples, output, and time and space complexity analysis for each method. Here are the different ways to add elements to an array: Use square brackets [] In PHP, the way to add elements to the end of an array is to use square brackets []. This syntax only works in cases where we want to add only a single element. The following is the syntax: $array[] = value; Example

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,
