This article mainly introduces the method of large-scale data submission in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.
The example of this article describes the method of large-scale data submission in PHP JS. The specific implementation method is as follows:
<?php session_start(); ?> <?php if($_SESSION["login"] != "YES") { echo "<script languge=javascript> alert('您没有登录,无权访问,请先登录!'); location.href='index.php'</script>"; } ?> <!DOCTYPE html> <html> <!-- InstanceBegin template="/Templates/tmplet.dwt.php" codeOutsideHTMLIsLocked="true" --> <head> <meta http-equiv="Content-Type" content="text/html;

myform.focus(); return false; } if(myform.content.value == '') { alert ("短消息内容不能为空!"); myform.focus(); return false; } } function moveOption1(e1, e2){ try{ for(var i = 0; i < e1.options.length; i++){ if( e1.options[i].selected ){ var e = e1.options[i]; e2.options.add(new Option(e.text, e.value)); e1.remove(i); i = i - 1; } } document.myform.msgto.value=getvalue(document.myform.list2); } catch(e){} } function moveOption2(e1, e2){ try{ for(var i = 0; i < e1.options.length; i++){ if(e1.options[i].selected ){ var e = e1.options[i]; e2.options.add(new Option(e.text, e.value)); e1.remove(i); i = i - 1; } } document.myform.msgto.value=getvalue(document.myform.list2); } catch(e){} } function getvalue(geto){ var allvalue = ""; for(var i=0;i<geto.options.length;i++){ allvalue +=geto.options[i].value + ","; } return allvalue; } function moveAllOption1(e1, e2){ try{ for(var i = 0;i < e1.options.length; i++){ var e = e1.options[i]; e2.options.add(new Option(e.text, e.value)); e1.remove(i); i = i - 1; } document.myform.msgto.value=getvalue(document.myform.list2); } catch(e){ } } function moveAllOption2(e1, e2){ try{ for(var i = 0;i < e1.options.length; i++){ var e = e1.options[i]; e2.options.add(new Option(e.text, e.value)); e1.remove(i); i = i - 1; } document.myform.msgto.value=getvalue(document.myform.list2); } catch(e){ } } --> </script> <!-- InstanceEndEditable --> </head> <body> <p id="container"> <p id="head"> </p> <p id="menu"> <ul> <li id="first_li"><a href="group.php">发送短信</a></li> <li><a href="send_box.php">发件箱</a></li> <li><a href="recv_box.php">收件箱</a></li> <li><a href="mynumber.php">管理电话薄</a></li> <li><a href="autoreply.php">添加自动回复</a></li> <li><a href="autoreply_ctl.php">管理自动回复</a></li> <li><a href="toadmin.php">联系管理员</a></li> <li><a href="logout.php">注销</a></li> </ul> </p> <p id="crumbs"> 短信管理 >>> <!-- InstanceBeginEditable name="EditRegion3" --> 发送短信 <!-- InstanceEndEditable --> </p> <p id="main"> <!-- InstanceBeginEditable name="EditRegion1" --> <?php require_once('connecting.php');

The above is the detailed content of PHP large-scale data submission method. For more information, please follow other related articles on the PHP Chinese website!

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.

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.

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.

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.

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
