This article mainly introduces the implementation of PHP obtaining form data and HTML embedding PHP scripts. It has a certain reference value. Now I share it with you. Friends in need can refer to it.

PHP accepts HTML When the form submits information, the submitted data will be saved in the global array. We can call the system-specific automatic global variable array to obtain these values.

Commonly used automatic global variables are as follows:

1. GET method

Function: Get the data submitted by get method

Format: $_GET["formelement"]

2. POST method

Function: Get the data submitted by post method

Format: $_POST["formelement"]

##3. REQUEST method

Function: Get data submitted in any way. The $_REQUEST automatic global variable contains all GET, POST, COOKIE and FILE data, if you don’t care about the data source.

Format: $_REQUEST["formelement"]

Check box, list box (the name is in the form of an array For example: "select[]", just use $_POST["select"] when getting its value)

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>
</head>

<body>
<!--获取表单数据的两种方法-->
<!--post-->
<form method="post" action="8.3.php" name="form1">
 <table border="1" width="400" cellpadding="0" cellspacing="0">
 <tr>
  <td height="30"> 用户名:<input name="txtName" type="text" size="12">
  密码:<input name="txtPsd" type="password" size="12">
  <input type="submit" name="SubmitBtn" value="提交">
  </td>
 </tr>
 </table>
</form><br/>

<!--get URL的长度需要限定在1M范围内，否则会截取-->
<!--可以使用urlencode与urldecode对URL进行编解码-->
<form method="get" action="8.3.php" name="form2">
 <table border="1" width="400" cellpadding="0" cellspacing="0">
 <tr>
  <td width="400" height="30"> 订单号:<input name="txtFrame" type="text" size="12">
  <input type="submit" name="SubmitBtn">
  </td>
 </tr>
 </table>
</form>

<!--在Web页面中嵌入PHP脚本-->
<?php
  $strTxt = &#39;男&#39;;
?>
<input type="text" value="<?php echo "strTxt"; ?>">

</body>

<?php
  echo &#39;用户名: &#39;.$_POST["txtName"]." 密码：".$_POST[&#39;txtPsd&#39;];
  echo &#39;订单号:&#39;.$_GET["txtFrame"];
?>

</html>

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
