PHP and Nginx file upload size limit issue

PHP large file uploads occupy a lot of resources, so the upload size needs to be limited. The following are the three relevant parameters:

client_max_body_size
upload_max_filesize
post_max_size

For some nginx php websites , the size of the uploaded file will be limited by many aspects. One is the limitation of nginx itself, which limits the size of the file uploaded by the client. The other is the default settings in multiple places in the php.ini file.

So in order to solve the problem of uploading file size limit, many modifications must be made. A few places are listed below.

Solution:

1. Modify the /usr/local/nginx/conf/nginx.conf file, find client_max_body_size and set the following value to what you want. value. For example:

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 
     # 
     location ~ \.php$ { 
       root      /home/www/htdocs; 
       fastcgi_pass  127.0.0.1:9000; 
       fastcgi_index index.php; 
       fastcgi_param SCRIPT_FILENAME /home/www/htdocs$fastcgi_script_name; 
       include    fastcgi_params; 
   
       client_max_body_size 35m;    #客户端上传文件大小设为35M 
       client_body_temp_path /home/www/nginx_temp;    #设置临时目录 
     }

2. Modify the php.ini file

upload_max_filesize = 8M  
post_max_size = 10M  
memory_limit = 20M 
max_execution_time=300 
file_uploads = On #默认允许HTTP文件上传,此选项不能设置为OFF。
upload_tmp_dir =/tmp/www

When uploading large files, you will feel that the upload speed is slow. When it exceeds a certain time, it will report that the script execution exceeds 30 The second error is due to the max_execution_time configuration option in the php.ini configuration file. It indicates the maximum allowed execution time (seconds) of each script, and 0 indicates no limit. You can adjust the value of max_execution_time appropriately. Setting it to 0 is not recommended.

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.

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.
