This article introduces the method of configuring the PHP server and the specific steps to build the PHP environment. Friends in need can refer to it.
Contents of this section: PHP server configuration method, PHP environment setup steps. The specific steps are as follows: 1. Unzip the installation package to C:/PHP (you can unzip it anywhere, the most important thing is to remember the path) 2. Copy all files in the sapi and DLLS directories to the PHP/ directory 3. Copy php.ini-dist to the C:WINDOWS directory and change it to php.ini (the default is this, but it can be changed by using the system environment variables. The environment variables are in "My Computer-Properties-Advanced-System Variables ( path or create a phprc yourself. The content is (php.ini path))") 4. Copy php4ts.dll to the WINDOWS directory 5. Modify upload_tmp_dir = "c:/tmp/" and give permission to the TMP folder. 6. Modify extension_dir = "C:/PHP/extension/" 7. Remove the following: extension=php_mbstring.dll extension=php_curl.dll extension=php_dbase.dll extension=php_gd2.dll extension=php_iconv.dll extension=php_ldap.dll extension=php_msql.dll extension=php_zip.dll8. session.save_path = "C:/tmp/" 9. Next configure IIS: Open "Control Panel" --> "Administrative Tools" --> "Internet Information Services (IIS) Manager", select "Website", and open its "Properties" window Select the "Home Directory" page, click the "Configure" button under "Application Settings", click the "Add" button in the new window; enter in "Executable File" "C:phpsapiphp4isapi.dll (if this doesn't work for the first time, you can try the php-cgi.exe file)", enter ".php" in "Extension", select "Limit to (L)" in "Action", and Enter in the input box "GET,HEAD,POST,TRACE", click "OK". Next, select the "Document" page, click the "Add" button; enter "index.php" in the "Default Document Name" , click OK, and raise it to the highest level. You can also add commonly used PHP file names, such as: "default.phtml", "index.php3", etc. 10. Next, select "Web Service Extension" in "Internet Information Services (IIS) Manager", right-click and select "Add a new web service extension". Enter "php" in the "Extension (x)" in the pop-up dialog box, and add "C:phpsapiphp4isapi.dll" in the "Required File (E)" (if this does not work for the first time, you can try php-cgi. exe)", Select "Set extension status to Allow" and click "OK". 11. Switch to the dos window, enter the net stop iisadmin command, press Enter, answer yes, press Enter, enter net start w3svc, press Enter, and close the dos window. PHP configuration is completed. 12. Write a phpinfo(); ?> Save to the default site as index.php 13. Browse successfully! PHP configuration successful. After completing the above, you will be able to see the basic information of PHP through phpinfo();, pay attention to the content (Configuration File (php.ini) Path and extension_dir (path format c:php) path are what you want) After modifying PHP.INI, check phpinfo(); if there is no change, you need to enter net stop iisadmin in CMD, then enter net start w3svc, and finally check. php server environment setup and configuration (apache and iis two methods) How to build a php server environment Configuring php server environment under ubuntu php and mysql server configuration instructions php class to get server information An alternative way to obtain server-side information using php php code to get server information |

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.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
