php新人请求知道,关于post传递的问题
PHP post传递
因为是刚学PHP,所以有很多不懂的地方,所以还请热心的朋友指导下。
回复讨论(解决方案)
不能直接在php标签中写文本内容,要显示要么echo,要么写到标签之外
text.php是什么东西...
后台代码修改为
<?phpecho "Welcome to my world!";echo "Welcome," . $_POST['name'];echo "You are " . $_POST['age'] . " old .";
字符串用双引号或者单引号包裹

这样是对的, lz那个text.php是干什么的?
楼主说出你的疑问让我帮你解答一下。
4楼的方法是对的。
接收form过来的值,当然用$_POST。
而且在页面中,也是要用 例如:
<?=$_POST['a']?>
一个不错的参考代码:
<?php/** * 发送post请求 * @param string $url 请求地址 * @param array $post_data post键值对数据 * @return string * @edit by www.jbxue.com */ function send_post($url, $post_data) { $postdata = http_build_query($post_data); $options = array( 'http' => array( 'method' => 'POST', 'header' => 'Content-type:application/x-www-form-urlencoded', 'content' => $postdata, 'timeout' => 15 * 60 // 超时时间(单位:s) ) ); $context = stream_context_create($options); $result = file_get_contents($url, false, $context); return $result; } //使用方法 $post_data = array( 'username' => 'stclair2201', 'password' => 'handan' ); send_post('http://www.qianyunlai.com', $post_data); <?php /** * Socket版本 * 使用方法: * $post_string = "app=socket&version=beta"; * request_by_socket('chajia8.com', '/restServer.php', $post_string); */ function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30) { $socket = fsockopen($remote_server, $port, $errno, $errstr, $timeout); if (!$socket) die("$errstr($errno)"); fwrite($socket, "POST $remote_path HTTP/1.0"); fwrite($socket, "User-Agent: Socket Example"); fwrite($socket, "HOST: $remote_server"); fwrite($socket, "Content-type: application/x-www-form-urlencoded"); fwrite($socket, "Content-length: " . (strlen($post_string) + 8) . ""); fwrite($socket, "Accept:*/*"); fwrite($socket, ""); fwrite($socket, "mypost=$post_string"); fwrite($socket, ""); $header = ""; while ($str = trim(fgets($socket, 4096))) { $header .= $str; } $data = ""; while (!feof($socket)) { $data .= fgets($socket, 4096); } return $data; } ?> <?php /** * Curl版本 * 使用方法: * $post_string = "app=request&version=beta"; * request_by_curl('http://www.qianyunlai.com/restServer.php', $post_string); */ function request_by_curl($remote_server, $post_string) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $remote_server); curl_setopt($ch, CURLOPT_POSTFIELDS, 'mypost=' . $post_string); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERAGENT, "qianyunlai.com's CURL Example beta"); $data = curl_exec($ch); curl_close($ch); return $data; } ?>
表单里面是input name='name'
你在$_POST里面也要小写 $_POST['name']
可以这样
echo "welcome".
?>
welcome
you are years old
可以这样
<?phpecho "welcome".?>welcome <?php echo $_POST["name"];?><br />you are <?php echo $_POST['age'];?> years old
可以这样
<?phpecho "welcome".?>welcome <?php echo $_POST["name"];?><br />you are <?php echo $_POST['age'];?> years old
11楼的做法是比较好的做法,就是在HTML中插入php代码

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.
