HomeBackend DevelopmentPHP TutorialPHP连接MYSQL数据库实例代码_php实例

现在做的项目需要php连接mysql数据库,虽然之前学过,但是现在基本上都给忘了,之后通过查找相关资料找到了解决方法,下面小编把具体方法分享在脚本之家平台供大家学习。

具体代码如下所示:

<&#63;php
//设置字符集
header('Content-Type: text/html; charset=utf8');
//连接数据库
$link = mysql_connect("localhost","root","123456");
if(!$link){
echo '数据库连接失败...<br>';
exit(-1);
}else{
echo "数据库连接成功...<br>";
}
//选择一个数据库作为默认数据库
mysql_select_db('php_sjk');
//执行sql插入语句
$sql = "INSERT INTO zh VALUES (NULL,'王杰','123456')";
$cr = mysql_query($sql);
//判断是否插入成功
if(!$cr){
echo "数据插入失败。<br>";
}else{
echo "数据插入成功。<br>";
}
//执行sql查询语句
$sql = "select * from zh";
$cr = mysql_query($sql);
//得到返回的结果集,并循环输出
echo "数据展示:<br><br><br>";
while($a = mysql_fetch_row($cr)){
echo "{$a[0]}——{$a[1]}——{$a[2]}<br>";
}
//关闭数据库连接
mysql_close($link);
&#63;>

关于PHP连接MYSQL数据库的代码就给大家介绍这么多,欢迎大家收藏,谢谢!

PHP vs. Python: Understanding the DifferencesPHP vs. Python: Understanding the DifferencesApr 11, 2025 am 12:15 AM

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 It Dying or Simply Adapting?PHP: Is It Dying or Simply Adapting?Apr 11, 2025 am 12:13 AM

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: Adaptations and InnovationsThe Future of PHP: Adaptations and InnovationsApr 11, 2025 am 12:01 AM

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.

When would you use a trait versus an abstract class or interface in PHP?When would you use a trait versus an abstract class or interface in PHP?Apr 10, 2025 am 09:39 AM

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.

Explain the SPL SplFixedArray and its performance characteristics compared to regular PHP arrays.Explain the SPL SplFixedArray and its performance characteristics compared to regular PHP arrays.Apr 10, 2025 am 09:37 AM

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.

How does PHP handle file uploads securely?How does PHP handle file uploads securely?Apr 10, 2025 am 09:37 AM

What is the Null Coalescing Operator (??) and Null Coalescing Assignment Operator (??=)?What is the Null Coalescing Operator (??) and Null Coalescing Assignment Operator (??=)?Apr 10, 2025 am 09:33 AM

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.
