废话不多说了,直接给大家贴代码了,具体代码如下所示:
<h插入操作</h <?php if(!isset($_POST['submit'])){ //如果没有表单提交,显示一个表单 ?> <form action="" method="post"> 国家:<input type="text" name="country" /> 动物名称(英文):<input type="text" name="animal" /> 动物名称(中文):<input type="text" name="cname" /> <input type="submit" name="submit" value="提交表单" /> </form> <?php } else { //如果提交了表单 //数据库连接参数 $host = "localhost"; $user = "root"; $pass = "zq"; $db = "phpdev"; // 何问起 hovertree.com //取得表单中的值,检查表单中的值是否符合标准,并做适当转义,防止SQL注入 $country = empty($_POST['country'])? die("请输入国家名称"): mysql_escape_string($_POST['country']); $animal = empty($_POST['animal'])? die("请输入英文名"): mysql_escape_string($_POST['animal']); $cname = empty($_POST['cname'])? die("请输入中文名"): mysql_escape_string($_POST['cname']); //打开数据库连接 $connection = mysql_connect($host, $user, $pass) or die("Unable to connect!"); //选择数据库 mysql_select_db($db) or die("Unable to select database!"); //构造一个SQL查询 $query = "INSERT INTO symbols(country, animal, cname) VALUE('$country', '$animal', '$cname')"; //执行该查询 $result = mysql_query($query) or die("Error in query: $query. ".mysql_error()); //插入操作成功后,显示插入记录的记录号 echo "记录已经插入, mysql_insert_id() = ".mysql_insert_id(); //关闭当前数据库连接 mysql_close($connection); } ?>
上面的代码用不同格式,不知道哪种格式更好
<h插入操作</h <?php if(!isset($_POST['submit'])){ //如果没有表单提交,显示一个表单 ?> <form action="" method="post"> 国家:<input type="text" name="country" /> 动物名称(英文):<input type="text" name="animal" /> 动物名称(中文):<input type="text" name="cname" /> <input type="submit" name="submit" value="提交表单" /> </form> <?php } else { //如果提交了表单 //数据库连接参数 $host = "localhost"; $user = "root"; $pass = "zq"; $db = "phpdev"; //取得表单中的值,检查表单中的值是否符合标准,并做适当转义,防止SQL注入 $country = empty($_POST['country'])? die("请输入国家名称"): mysql_escape_string($_POST['country']); $animal = empty($_POST['animal'])? die("请输入英文名"): mysql_escape_string($_POST['animal']); $cname = empty($_POST['cname'])? die("请输入中文名"): mysql_escape_string($_POST['cname']); //打开数据库连接 hovertree.com 何问起 $connection = mysql_connect($host, $user, $pass) or die("Unable to connect!"); //选择数据库 mysql_select_db($db) or die("Unable to select database!"); //构造一个SQL查询 $query = "INSERT INTO symbols(country, animal, cname) VALUE('$country', '$animal', '$cname')"; //执行该查询 $result = mysql_query($query) or die("Error in query: $query. ".mysql_error()); //插入操作成功后,显示插入记录的记录号 echo "记录已经插入, mysql_insert_id() = ".mysql_insert_id(); //关闭当前数据库连接 mysql_close($connection); } ?>
以上所述是小编给大家介绍的PHP表单数据写入MySQL数据库的代码 ,希望对大家有所帮助!

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.
